Under the guidance of the policy of "carbon peaking and carbon neutrality", the power grid presents a green and low-carbon development trend. The random output characteristic of distributed generation leads to frequent voltage fluctuations and serious harmonic pollution; Electric vehicles and controllable loads increase the peak-valley difference of power grid and the difficulty of regulation and control. As independent individuals, distributed energy sources such as distributed generation, electric vehicles, energy storage and controllable loads are small in scale and scattered in layout, which pose challenges to the operation, maintenance, protection and dispatching of power grid. Therefore, the concept of virtual power plant came into being. By deploying advanced measurement technology, information and communication technology and regulation control technology in resource nodes such as distributed generation, energy storage, EVs and controllable load, as well as joint coordinated control, the system has realized the optimal allocation of distributed generation, demand response resources and other resources in the virtual power plant, and for the external power grid, it is embodied as a unified power consumption and generation cluster to deeply tap the regulation potential of various internal resources.
Virtual Power Plant Control and Management System
he solution is for customers including electric power companies, load aggregators, virtual power plant aggregators, energy storage operators and charging operators, and can be applied to the aggregation of distributed energy resources such as distributed PV, distributed wind turbines, energy storage, electric vehicles, gas turbines and controllable loads.
