摘要：
Due to the fact that power fluctuation caused by wind power, photovoltaics and electric vehicle charging threatens the safe operation of microgrid, based on the relationship between electric throughput and the depth of charging and discharging in the whole life of lead carbon battery, an optimization strategy for path switching of charging and discharging mode controlled by operation balance index of double battery energy storage system (DBESS) is proposed, and a charging and discharging control strategy of DBESS based on the best depth of charging and discharging of lead carbon battery is proposed. Calculation results of the strategy proposed and traditional strategy are compared by using actual operational data of wind power, photovoltaics, double lead carbon battery energy storage system, lithium-ion electric vehicle charging and regular load. Results show that the proposed strategy can not only optimize the path of charging and discharging mode, but also break the restriction of state of charge consistency between beginning and end of the charging and discharging process in the DBESS, so that the available capacity can be increased to the most extent and the flexibility of the use of battery energy storage system can be enhanced. The rationality and validity of the proposed strategy are finally verified by charging and discharging saturability index and stability index of DBESS. © 2019 Automation of Electric Power Systems Press.
