Research on Virtual Power Plants Participating in Ancillary Service Market

Abstract

Under the “Double Carbon” strategy, the speed of new energy installation and grid connection has been continuously improved. In order to better absorb new energy power generation and ensure the safe and stable operation of the power system, it is urgent to provide ancillary service resources such as frequency regulation and peak shaving. The virtual power plant aggregates the distributed energy scattered in the power grid through advanced communication, computing, dispatching, market and other means, making it a “power generation system” that can be uniformly dispatched, and then follow the dispatching instructions and participate in the ancillary service market. Firstly, the relevant structure and development of virtual power plant is introduced. Secondly, the relevant types of virtual power plants participating in the ancillary service market are analyzed. Thirdly, the actual situation of virtual power plants participating in ancillary service markets for frequency regulation and peak shaving is compared and analyzed with reference to the market access conditions, compensation mechanism and allocation mechanism, which lays a theoretical foundation for different provinces to further improve the mechanism of virtual power plants participating in ancillary service markets. At last, according to China’s national conditions, suggestions on the construction of market mechanism for virtual power plants to participate in ancillary services are proposed.
