Abstract

Virtual power plant(VPP) is the idea of using other devices or scheduling policies to balance the energy of power system. While maintaining the stable operation of the system , and it is also necessary to improve the economy and environmental protection of the power grid system. This method can aggregate distributed energy resource (DER) for stable transmission to the public grid without reforming the power grid, and provide fast response auxiliary services. It is an effective method for DER to join the power market, reduce the risk of imbalance of its lonely operation in the market, and obtain the benefits of scale economy. Demand response (DR) provides a critical channel for the demand side to interact with the power grid in a flexible manner. In this paper, a control strategy of VPP with temperature controlled loads considering user comfort is proposed. Firstly, a single air source heat pump loads model is established, and then a large number of air source heat pump loads are aggregated to establish a VPP model considering the user comfort constraints as the output boundary. Finally, a case simulation analysis of a distributed distribution network system in a certain area is carried out, and the effectiveness of the model is verified, which provides a new technical way for VPP modeling based on loads response.
