The Lecture is:

Virtual Energy Storage Operation of PV Systems for Frequency Support



The still increasing penetration of renewable energy systems challenges the stability of the grid. Accordingly, towards the integration of more electronics- or inverter-based renewable generation systems, including photovoltaic (PV) systems, many advanced grid supportive functions have been developed. In recent years, relevant and stringent requirements have been released to guide the grid integration of solar PV systems. Such inverter-based systems have a distinct difference, i.e., low inertia or non-inertia systems, compared to the conventional synchronous generators, potentially leading to frequency instabilities. To tackle the frequency stability issue, many efforts like virtual synchronous generator control and the integration of energy storage have been made in recent years. Among those, a flexible active power control scheme is gaining much attention, when compared with the integration of energy storage. In this talk, the active power control strategies for PV systems will be briefly reviewed, and then, the focus will be put on the power reserve control for PV systems. This enables the PV systems to operate as virtual energy storage units that can flexibly and cost-effectively provide grid frequency support, enhancing the grid integration of PV systems.



Prof. YANG Yongheng (SM’17) received the B.Eng. degree in Electrical Engineering and Automation from Northwestern Polytechnical University, China, in 2009 and the Ph.D. degree in Energy Technology (power electronics and drives) from Aalborg University, Denmark, in 2014.
He was a postgraduate student with Southeast University, China, from 2009 to 2011. In 2013, he spent three months as a Visiting Scholar at Texas A&M University, USA. Since 2014, he has been with the Department of Energy Technology, Aalborg University, where he became a tenured Associate Professor in 2018. In January 2021, he joined Zhejiang University, China, where he is currently a ZJU100 Professor with the Institute of Power Electronics, College of Electrical Engineering. His current research interests include the grid-integration of photovoltaic systems and control of power converters, in particular, the mechanism and control of grid-forming power converters and systems.
Prof. YANG was the Chair of the IEEE Denmark Section (2019-2020). He is an Associate Editor for several IEEE Transactions/Journals. He is a Deputy Editor of the IET Renewable Power Generation for Solar Photovoltaic Systems. He was the recipient of the 2018 IET Renewable Power Generation Premium Award and was an Outstanding Reviewer for the IEEE TRANSACTIONS ON POWER ELECTRONICS in 2018. He received the 2021 Richard M. Bass Outstanding Young Power Electronics Engineer Award from the IEEE Power Electronics Society (PELS). In addition, he has received two IEEE Best Paper Awards. He is currently the Secretary of the IEEE PELS Technical Committee on Sustainable Energy Systems and a Council Member of the China Power Supply Society.
