Abstract
Battery energy storage system based on droop control strategy is widely used in island power station to keep stable operation of the system.Considering factors such as random,excursion of battery characteristic curve and output disturbance of running points of battery storage equipments,there must be differences of state of charge (SoC)of paralleled battery en-ergy storage system in discharge process.Therefore,a kind of droop control strategy for SoC error suppression was proposed to remove SoC errors among different storage equipments in running process of paralleled storage equipments.Damages to stable operation of island power grid caused from SoC errors of paralleled battery energy storage system were analyzed under the condition of traditional droop control.Then,SoC was introduced into active droop factor to decease SoC errors of stor-age equipments with curve of e index and reduce impact on the system in process of error convergence.In addition,charac-teristic of differential equation of first order was combined to adjust accelerated factor in control strategy and speed up sup-pression on SoC errors among paralleled battery energy storage system.Simulation results verified veracity of this theory and effectiveness of this scheme.关键词
