Energy Optimal Management of Microgrid with High Photovoltaic Penetration

For microgrid with high photovoltaic penetration, the optimized energy management strategy can not only improve the microgrid benefits effectively, but also ensure the safety and stability of island microgrid. This paper establishes a multi-objective energy optimization model of the microgrid with high photovoltaic penetration based on the photovoltaic operation and maintenance costs, the energy storage system operating life loss, the thermal power environmental pollution and governance costs, the electricity trading from grid, and the fine for controllable load shedding. Then obtain energy optimal management strategy by particle swarm algorithm with inertial weight factor. Finally, the proposed energy optimal management system is verified on a typical microgrid by simulation.
