An economical operation strategy of multi-energy virtual power plant in a distribution network

The overproduction of renewable energy resources (RES) has led to increased stability problems in power systems. Technological development and validation of sector coupling, multi-energy systems, and power-to-X are underway to address this issue. Power-to-heat (P2H) is a possible solution that can be adopted rapidly by the power industry. Use of P2H can be more economical than using only electrical power resources to solve problems in distribution systems. In this study, we propose an operation strategy for a multi-energy virtual power plant (MEVPP) with distributed energy and P2H resources. When stability problems occur, an MEVPP adjusts the resource operating schedule according to grid constraints. The proposed strategy is verified by case studies based on an IEEE-33 bus system using SGSim.
