Optimal Energy for Grid-Connected Microgrid with Battery Swapping Station and Wind Photovoltaic and Energy Storage

In this paper, an optimal dispatch strategy, which can take into account the period division of time of use, the output power of renewable energy sources (RES) and replacement demand for batteries, is proposed. On this basis, by optimizing the battery swapping station (BSS) load in each period, an optimization model is established to minimize the power interaction between microgrid and the distribution network. An optimization algorithm is developed based on the well-established particle swarm optimization (PSO) and penalty function method to solve the power dispatch model. The proposed approach is demonstrated through an existing microgrid.
