摘　　要：提出了一种模型,分析微电网储能系统(energy storage system,ESS)的大小与经济效益之间的关系。以提高微电网的经济效益为目标,计算出ESS最佳大小。ESS越大,投资成本就会越高,但微电网的运行成本会随之下降。最佳ESS大小问题的研究,包括最大限度地减少了ESS的投资成本,以及微电网运行成本。建立一个包含ESS的实用模型,使用不同的运行策略,验证了最佳ESS大小的经济性和运行可靠性。A model,analysis of the relationship between the size of microgrid energy storage system （ESS） and its economic is presented.The goal is to improve the microgrid economic efficiency,and calculates the optimal size.The larger size of ESS,the investment costs will be higher,but the operating costs of microgrid will decline.The study of optimal ESS size,include minimizing investment costs,as well as microgrid operating costs.A useful ESS model,using different operating strategies,verify the economy and operation reliability of optimal ESS size is established.
