Research Interests

Zhong is the Max McGraw Endowed Chair Professor in Energy and Power Engineering and Management at �Ӱ�ԭ�� Institute of Technology and the founder and chief executive officer of . Before moving to the United States in 2014, Zhong established a distinguished academic career in the United Kingdom, culminating in his appointment as Chair Professor of Control and Systems Engineering at the University of Sheffield and in the formation of the foundational SYNDEM architecture and VSM technology framework. At Sheffield, he established a $5M+ research laboratory dedicated to the control of energy and power systems, with support from organizations including Rolls-Royce, National Grid, National Instruments, Texas Instruments, Siemens, ALSTOM, Turbo Power Systems, Chroma, Yokogawa, OPAL-RT, and others. A researcher, educator, inventor, and entrepreneur, he integrates systems science, control theory, power electronics, power systems, hardware engineering, and technology translation. His body of work—including four research monographs, more than 250 peer-reviewed publications, and a patent portfolio comprising eight U.S. patents and 17 foreign patents, with seven inventions protected in both U.S. and foreign jurisdictions—has reshaped how power-electronic grids are conceived, controlled, coordinated, and implemented, addressing one of the defining global challenges of the twenty-first century: creating stable, coordinated, and resilient energy systems that advance energy freedom and equity.

SYNDEM: A Field-Defining Architecture for Power-Electronic Grids

�ܳ�DzԲ�’s most transformative contribution is his invention of SYNDEM—a field-defining architecture that integrates synchronization principles in the natural sciences with democracy concepts in the social sciences—as detailed in his sole-authored and . Democratization gives many participants freedom, but not the common physical rule needed for stable coordination or consensus—a limitation illuminated by ’s . SYNDEM supplies that rule by making the synchronization mechanism of synchronous machines, which has underpinned power-system operation for more than a century, the common physical law for heterogeneous conventional and power-electronic resources.

Under SYNDEM, conventional and renewable generation, network converters, energy storage, electric vehicles, and, critically, flexible loads are unified within a common framework and can equally participate in voltage and frequency regulation according to their capacity. This creates a backward-compatible universal interface through which power-electronic resources can work with the existing synchronous-machine-based grid, while supply-, network-, and demand-side converters become active participants in system stability. Flexible loads can provide continuous primary frequency and voltage response instead of only binary load shedding, mobilizing flexibility and stored energy already present in motors, vehicles, storage, and other devices.

SYNDEM also separates physical coordination from digital supervision. Synchronization and low-level stability arise through electrical interaction without depending on continuous high-speed communication or a central controller, providing a communication-independent layer of decentralized cyber-physical grid security against external telecommunications disruption or manipulation; digital systems remain essential for monitoring, management, markets, and optimization, and can provide optional supervisory set-points. Through energy bridges, SYNDEM enables local systems to black-start, regulate voltage and frequency, merge, island, recover, resynchronize, and reconnect autonomously—supporting scalable self-organization while containing disturbances and reducing cascading-failure risk.

Pioneering and Field-Shaping Virtual Synchronous Machine Technologies

To implement SYNDEM, Zhong pioneered VSM technologies that enable power-electronic converters to behave as grid-forming synchronous machines. Earlier VSM approaches such as VISMA used synchronous-machine models to generate current references, leaving the converter as a controlled current source dependent on an existing grid voltage. Recognizing that power systems are organized around voltage sources, Zhong invented by embedding synchronous-machine equations directly into converter-voltage generation. The synchronverter was the first practical, experimentally validated voltage-controlled VSM—a grid-compatible voltage source capable of forming its own waveform and regulating active and reactive power—and redefined the field. The seminal synchronverter paper ranks among the three most-cited non-survey papers in the 44-year history of IEEE Transactions on Industrial Electronics, with nearly 4,000 Google Scholar citations as of June 29, 2026.

Building on this breakthrough, Zhong drove successive generations of VSM technology. His 2014 paper on demonstrated an inherent synchronization mechanism through electrical interaction without measuring grid frequency or using a dedicated phase-locked loop, eliminating the separate synchronization unit then widely regarded as necessary. By making synchronization intrinsic to converter control, this work is setting a new industry norm for converter-dominated power systems. He also identified and corrected three fundamental weaknesses of conventional droop control and invented for accurate proportional power sharing and tight voltage and frequency regulation despite component mismatches. He then developed to enable the parallel operation of converters with different impedance characteristics. By revealing the , he provided a mathematical foundation for inherent self-synchronization and established universal robust droop control as a second-generation VSM technology. The self-synchronization paper ranks among the top 30 most-cited non-survey papers in the 40-year history of IEEE Transactions on Power Electronics, with 1,350+ Google Scholar citations as of June 29, 2026; the robust-droop control paper had more than 1,100 Google Scholar citations as of the same date.

�ܳ�DzԲ�’s , “Virtual Synchronous Machines: A Unified Interface for Grid Integration,” synthesized the synchronverter and related developments into a coherent framework. It ranked among the magazine’s two most-cited and two most-popular papers as of June 2026 and was recognized as its Top Paper of 2016. His subsequent advances introduced bounded voltage and frequency, impedance shaping, current limiting, and reconfigurable inertia and damping.

Together, this sustained sequence of inventions and field-shaping scholarship transformed VSMs from a machine analogy into a robust, interoperable, and scalable technology family that enables the SYNDEM architecture.

Scalable Mathematical Foundations for System-Level Stability

As lead author, Zhong established scalable mathematical foundations for passive converter control and network-wide stability in converter-dominated power systems. The developed a port-Hamiltonian framework that makes grid-tied or islanded converters behave as VSMs and renders the closed-loop system passive without assuming constant frequency, voltage, or loads. The integrated port-Hamiltonian systems theory with fundamental circuit theory to develop compact, scalable modeling and control frameworks for converter-dominated power systems with an arbitrary number of converters, passive controllers and loads, and meshed passive transmission and distribution lines. Both the controlled converters and the resulting systems are passive and input-to-state stable, showing that local passivity and stability guarantees can be composed across the network for SYNDEM grids of arbitrary scale.

Global Field Leadership: Institutional Transformation and Policy Impact

Soon after inventing the synchronverter in 2008, while based in the United Kingdom, Zhong launched a global initiative to build worldwide technical and institutional momentum around the emerging VSM direction. Through more than 200 invited lectures in more than 20 countries and sustained engagement with universities, research centers, utilities, industry, and public institutions, he advanced the SYNDEM architecture and its enabling VSM technologies from foundational invention and research into a global engineering direction. The initiative unfolded through complementary pathways: technical and institutional transformation culminating in utility-scale demonstration in China; multidisciplinary field building, policy engagement, and federal technology development and validation in the U.S., followed by convergence with major national research priorities; regulatory translation in Great Britain; and global standardization through IEEE Std 2988-2024.

The clearest . During his earlier UK-based career, after inventing the synchronverter in 2008, Zhong introduced and championed VSM technology through dozens of lectures in China, convinced State Grid of VSM technology’s importance and secured State Grid funding for a dedicated collaborative project between the China Electric Power Research Institute (CEPRI) and the University of Sheffield, and led the dedicated VSM project team at CEPRI beginning in 2012. Zhong moved to the U.S. in August 2014, and the UK-based collaboration later concluded after the project was completed. The technical and institutional foundation he had established proved decisive in State Grid’s subsequent decision to designate VSM technology as one of its Ten Key Science and Technology Innovation Projects and undertake a utility-scale VSM demonstration. His invention, advocacy, program initiation, and technical and institutional leadership converted an original research direction first into State Grid’s institutional commitment and then, through State Grid’s independent implementation and commissioning, into , with by the implementing organizations.

A complementary institutional and policy pathway unfolded in the U.S. Years before grid-forming technologies became a consortium-scale U.S. federal research category, Zhong had already articulated the underlying direction and begun building U.S. institutional momentum through his global initiative. An early U.S. component of the initiative was a that he initiated in October 2010 and undertook in 2012–2013. He visited and delivered lectures on the architecture and its enabling VSM technologies at three NSF-established Engineering Research Centers: Center for Power Electronics Systems (CPES), Future Renewable Electric Energy Delivery and Management Systems Center (FREEDM), and Center for Ultra-wide Area Resilient Electric Energy Transmission Networks (CURENT); one NSF Industry–University Cooperative Research Center: Grid-Connected Advanced Power Electronic Systems (GRAPES); two U.S. national laboratories: National Renewable Energy Laboratory (NREL) and Oak Ridge National Laboratory (ORNL); and approximately 20 leading U.S. universities. In September 2013, , autonomous voltage and frequency regulation, and no central coordination. After moving to the U.S., he progressively advanced this direction through technical synthesis, policy engagement, multidisciplinary field building, federal technology development, and global standardization. His invited, sole-authored 2016 cover story framed VSMs as In 2017, Michael Pesin, then Deputy Assistant Secretary at the U.S. Department of Energy, invited Dr. Zhong to DOE headquarters for focused technical discussions on SYNDEM and VSM technologies and stated, “Sooner or later, this will be deployed worldwide.” In 2018, the SYNDEM architecture and VSM technologies were cited in the bringing their implications for grid resilience and energy independence into the congressional record.

In early 2019, Zhong initiated and secured NSF support for and chaired a , held at �Ӱ�ԭ�� Tech from October 31–November 1, 2019. It convened the control, power-electronics, and power-systems communities and attracted from government agencies, regulatory commissions, utilities, industry, research organizations, and universities. The NSF also awarded a , active from September 2019–August 2020. In November 2019, DOE announced an award to Syndem for a project led by Zhong . The project began in February 2020. Together, these NSF- and DOE-supported initiatives demonstrate his leadership in convening the field, advancing a center-scale research vision, and developing communication-network-independent autonomous power systems.

In December 2020, while �ܳ�DzԲ�’s DOE project was underway, DOE issued a funding opportunity . On January 22, 2021, Zhong , and on March 31, 2021, DOE invited him to present “Next-Generation Smart Grids: Autonomous Power Systems” to policymakers and senior engineering leaders, including C. D. Mote Jr., former President of the National Academy of Engineering.

In August 2021—13 years after he invented the synchronverter, eight years after IEEE Spectrum featured his proposal for completely self-controlled power systems with millions of active participants, and five years after his 2016 cover story framed VSMs as —DOE selected and funded to develop universal guidelines for seamless integration of inverter-based resources. Nearly another four years later, in January 2025, DOE’s Advanced Research Projects Agency–Energy announced the to advance grid coordination, protection, real-time control, stability, and resilience.

These landmark federal initiatives demonstrate that a unified interface for grid integration and the associated needs for interoperability, automatic damping and inertia, autonomous synchronization, coordinated control, and grid stability—an engineering direction Zhong had articulated and advanced for many years through the SYNDEM architecture and its enabling VSM technologies—subsequently emerged as major U.S. federal research priorities. This chronology underscores his engineering foresight and the enduring significance of the direction he defined and pioneered.

Great Britain served both as the original base of his global initiative and, later, as a distinct pathway of regulatory impact. Through sustained engagement with National Grid Electricity System Operator, now the National Energy System Operator, and participation in its VSM Expert Group, Zhong contributed to the technical foundation for , which established a specification for grid-forming capability.

Taken together, these complementary pathways within the global initiative Zhong started while based in the United Kingdom—the State Grid pathway in China, the field-building and NSF–DOE pathway in the United States, the grid-code pathway in Great Britain, and the global standardization achieved through his initiation of and leadership of its development—demonstrate his sustained global field leadership.

Validating SYNDEM Across Scales: Hardware and Field Demonstrations

The global initiative was grounded in engineering proof. Zhong validated SYNDEM and its enabling VSM technologies across physical systems, field tests, commercial operation, and independent utility-scale demonstration.

He established the world’s first 100-percent-power-electronics-based SYNDEM smart-grid testbed, in which eight heterogeneous physical VSM nodes were connected to a common AC bus and collectively regulated voltage and frequency without ICT-based low-level coordination. Presented in his , featured by and , and documented in his , it provided architecture-level physical proof that a fully converter-based grid could coordinate autonomously under SYNDEM.

Validation then advanced from an autonomous integrating solar, wind, storage, and utility-grid interaction to with solar panels, batteries, and the utility grid under grid-connected and islanded conditions, as part of a . At system scale, , comprising 108 physical power converters, provides infrastructure for system-level validation, resilience research, and workforce development.

The autonomous operation of Syndem’s five commercial VSM units further demonstrates repeatable SYNDEM behavior, including black-start, voltage and frequency regulation, grid detection, self-synchronization and connection, islanding, and resynchronization and reconnection.

Validation also reached utility scale. The technical and institutional foundation Dr. Zhong established during his U.K.-based career as part of his global initiative proved decisive in . In 2017, State Grid, the world’s largest utility, , comprising 59 wind turbines totaling 118 MW, 24 photovoltaic inverters totaling 12 MW, and two five MW station-level VSM units. Reported at the time as the world’s largest VSM demonstration, of the broader VSM direction that Zhong had pioneered and defined, with field measurements demonstrating critical virtual inertia (synthetic inertia) and robust fault ride-through capabilities in the transmission-connected project.

Global Standardization of VSM Technologies: IEEE Std 2988-2024

Zhong initiated and chaired the working group that developed it from ideation through publication. Completed nine months ahead of schedule with 97 percent approval, it became the first global standard dedicated to virtual synchronous machines. It defines their fundamental principles and essential and optional functions for single-unit, multi-unit, islanded/off-grid, and grid-tied operation, providing a common framework for standardizing power-electronic converters across applications, integrating distributed energy resources at scale, and advancing energy freedom and access.

affiliated with GE, Siemens, Hitachi, ABB, Eaton, Schneider Electric, NERC, EPRI, ERCOT, MISO, Southern California Edison, National Grid, Energinet, and CLP Power Hong Kong. Their participation demonstrates that VSM technologies have moved beyond an academic specialty into a shared engineering framework spanning manufacturers, research and reliability organizations, system operators, and utilities. Approved in 2024 and published in 2025, IEEE Std 2988-2024 institutionalized VSM technologies globally, carrying �ܳ�DzԲ�’s work from pioneering invention and field-shaping scholarship through physical validation and utility-scale demonstration into global technical consensus and engineering practice.

Commercialization and Engineering Translation

Zhong has translated successive generations of VSM technology into engineering practice through two distinct commercialization routes. During his UK-based career, the synchronverter patent family was licensed to for commercialization of first-generation VSM technology. Synvertec subsequently attracted public and private support from Horizon GreenTech Ventures, Israel Electric Corporation, the Israeli government, and the European Union’s Horizon 2020 program, creating an independent commercialization pathway for the foundational invention.

In 2017, Zhong founded in the greater Chicago area to develop and commercialize later-generation VSM technologies, including second-generation VSMs based on universal robust droop control, and to extend SYNDEM into products, manufacturing, field validation, education, licensing, and partnerships. Syndem has carried out technology development and validation through four federally supported projects, completed DOE-supported field tests involving 20 VSM-equipped converters, and established in-house capabilities to design, test, and manufacture converters up to 20 kW. As an industry partner in a DOE-supported project led by Binghamton University and involving Brookhaven National Laboratory, Syndem manufactured and delivered 30 VSM units.

Syndem’s reconfigurable and reprogrammable Smart Grid Research and Educational Kits have been adopted by institutions in more than 10 countries, while its VSM products have been sold to customers in three countries. Cumulative product sales exceeded $1.6 million as of June 2026. In March 2026, for joint marketing, integration, and sales, combining real-time simulation and hardware-in-the-loop testing with VSM products and reconfigurable physical hardware to provide an end-to-end pathway from modeling to experimental validation.

Together, the Synvertec and Syndem routes demonstrate sustained translation from foundational invention through licensing, federally supported development, field testing, manufacturing, customer delivery, international sales, and an expanding engineering ecosystem. The two routes remain technically and institutionally distinct: Synvertec pursued commercialization of licensed first-generation VSM (synchronverter) technology, while Syndem develops later-generation VSM technologies. Syndem’s operations are also institutionally separate from �ܳ�DzԲ�’s academic activities at �Ӱ�ԭ�� Tech.

Global Field Building: Education and Workforce Development

Zhong has built a global community around SYNDEM and VSM technologies through sustained international lecturing, scholarly resources, hands-on education, technical training, competitions, workshops, and mentorship. He has delivered more than 200 invited lectures in more than 20 countries, including 26 plenary and keynote talks, and has been appointed a distinguished lecturer by the IEEE Control Systems, Power Electronics, and Power and Energy Societies. He has authored four research monographs and organized 14 workshops and tutorials at major international conferences. He developed reconfigurable and reprogrammable SYNDEM Smart Grid Research and Educational Kits to enable hands-on education and research; the kits have been adopted by institutions in more than 10 countries.

He established VSM as one of the two topics of the , attracting 12 proposals from six countries and culminating in hardware testing by seven finalist teams and an 80-plus-person workshop. He also led a that convened more than 130 participants from government, industry, utilities, research organizations, and universities.

During his UK-based career, Zhong mentored doctoral students who received the IET Control and Automation Doctoral Dissertation Award and Chinese National Awards for Outstanding Students Abroad, including one Grand Prize. He also founded and led the EPSRC-supported , which attracted more than 200 members and helped lay the groundwork for today’s , with many former members now leading in academia and industry.

Media Recognition and Public Engagement

Across more than a decade, professional reporting and public commentary have traced �ܳ�DzԲ�’s work from architectural vision to present-day grid urgency. In 2013, IEEE Spectrum—IEEE’s flagship publication—introduced his proposal for with millions of active participants, while SmartGridNews.com described the emerging concept as a IEEE Spectrum later presented in 2017. Canary Media described synchronverter technology as a potential Keith Schneider, a veteran New York Times correspondent, compared the invention to the kind of breakthrough that helps move an industry from one era to the next and identified it as a technical route toward a more distributed and participatory energy system. In 2025, IEEE Spectrum published an editorially selected feature article led by Zhong, explaining .

Zhong has actively translated complex power-system ideas for public officials, regulators, utilities, investors, and the wider public. He has authored articles for American City & County and Impact, contributed to IEEE Smart Grid, delivered a distinguished lecture at the Institute of Public Utilities Grid School, and participated in a Science News Radio Network interview. He has also used LinkedIn to explain technical advances, field tests, educational platforms, standards, and technology adoption, with a recent post reaching approximately 60,000 impressions as of June 2026. As a semifinalist in the $1 million NYSERDA 76West Clean Energy Competition, he presented the technology directly to public and investor audiences, extending its reach from scientific and professional communities into entrepreneurship and public understanding.

Interdisciplinary Thinking Across Fields and Scales

�ܳ�DzԲ�’s work combines rare interdisciplinary breadth with sustained technical depth across fields and engineering scales. Beginning as a practicing hardware engineer and expanding into software development, he combined hands-on implementation with rigorous theory and built deep expertise in systems science, control theory, power electronics, and power systems. He connected these fields across scales—from circuits, converters, and control algorithms to network-wide stability and power-system architecture—and across domains by merging synchronization principles in the natural sciences with democracy concepts in the social sciences. This integrative thinking enabled him to build a coherent body of work that connects mathematical foundations and converter-level inventions with the SYNDEM architecture, hardware implementation and field validation, international standards, institutional transformation, education, and commercialization.
