Economic Analysis of Regional Microgrids Participating in Electricity Market

Nowadays, in developed megacities, more and more distributed power sources and electric vehicles are connected to microgrids. This article proposes a regional microgrid consisting of a combined heat and power system and a series of plug-in electric vehicles. Its main purpose is to provide auxiliary services and fully utilize renewable energy by integrating PEVs into fast response storage to improve the energy utilization and economic benefits of the system. The parking lot will gather to form a cluster of power electronic equipment and sign bilateral contracts with CHP to participate in regulating the electricity market. Propose an improved crow algorithm to solve the problem. Numerical simulation of the algorithm shows that if regional microgrids participate in electricity market regulation, the economic value per megawatt significantly increases and the total profit increases.
