Strategy Analysis of Virtual Power Plants Participation in Electric Power Market with Community Energy Internet

  Introduction  The paper aims to reduce the intermittent, random, uncontrollable effects of DERs capacity represented by wind and solar energy, and to participate in the competition in the power market, a community-based energy Internet model is proposed.

  Method  Considering a community-based energy Internet model consisting of a virtual power plant (VPP) cluster consisting of a wind farm, a photovoltaic power station, and a load, interconnecting a single VPP, and based on the balance of supply and demand within a single VPP, the surplus power game sharing through VPP clusters, and finally trading with the electricity market to achieve reverse sales.

  Results  The results we obtained demonstrate that the goal of maximizing the benefits of community-based energy Internet, and adding demand response (DR) to achieve the purpose of saving electricity for users.

  Conclusion  This work through the community energy Internet demonstration project, the VPP operation strategy model is proposed, and the feasibility of verifying the power generation strategy in different scenarios is established through the established benefits, which indicates the direction for the construction and transaction of the community energy Internet.
