Multi-Virtual Power Plant-Oriented Dynamic Aggregation Control Strategy Based on Hierarchical Partition and Multi-Layer Complementation

Abstract

Virtual power plant (VPP) is a new type of operation mode. It can effectively aggregate a large number of demand side resources and formulate effective dynamic aggregate control strategies to achieve power complemen-tation in different time and space of the power grid and improve the flexibility of power grid control and the economy of the system. From the perspective of power grid dispatching, this paper analyzed the characteristics of typical power grid demand response behavior, and proposed the demand response capability indexes and the classification and aggregation method of VPP. Then, a multi-source VPP regulation model was constructed, and the results supported the hierarchical and regional complementary regulation of VPP response resources. Finally, taking a park as a case, the rationality of VPP control strategy and the scientificity of multi-source VPP control were analyzed. The results show that the overall dynamic control strategy can guide the VPP to give full play to the demand response value in a scientific and reasonable way, and promote the stable load of power grid and the safe and stable operation of the system.
