摘　　要：以包含风、光、柴、储4种分布式电源的并网型微电网为研究对象,建立以经济性、环保性和供电可靠性为单个评价指标的多目标函数模型,并采用层次分析法(AHP)确定权重。综合考虑分布式电源(DG)的出力和安全性约束,设计关于并网型微电网的2种调度策略。讨论蓄电池充放电的深度和次数对寿命的影响,利用加权吞吐量法建立蓄电池寿命评价模型。采用改进的布谷鸟搜索算法(ICS)优化求解。在2种调度策略下进行算例对比,验证ICS算法的优越性以及调度策略对于蓄电池寿命的影响。The grid-connected microgrid,which includes wind,light,diesel and storage,is taken as the research object.A multiobjective function model with economy,environmental protection and power supply reliability as single evaluation index is established,and the analytic hierarchy process(AHP)is used to determine the weight.Considering the output and security constraints of distributed generation(DG),two scheduling strategies for grid-connected microgrids are designed.The effects of the depth and times of charge and discharge on the battery life are discussed,and the weighted throughput method is used to establish the battery life evaluation model.An improved cuckoo search(ICS)algorithm is used to optimize the solution.The advantage of ICS algorithm and the influence of scheduling strategy on battery life are verified by comparing the two scheduling strategies.
