摘　　要：针对独立海岛微网中分布式电源容量配置问题,建立计及设备初始投资成本、替换与维护成本、燃料成本、环境治理及缺电惩罚成本的微网经济性优化模型,考虑可再生能源装机容量比例、弃风光比例和供电可靠率等多种约束条件,并调用CPLEX软件中的MILP求解函数对建立的混合整数模型进行求解,分析比较了风光储、风光柴、光储柴、风储柴和风光储柴五种配置方案。最后通过灵敏度分析,定量考察供电可靠率、弃风光比例、燃料价格和储能电池SOC下限对优化结果的影响。To solve the capacity configuration of distributed generation in island standalone microgrid, this paper built an economic optimization model. This model takes equipment initial investment, replacement and maintenance cost, fuel cost, environment management cost, and electricity shortage penalty cost into account. And then it is solved by calling MILP solver of CPLEX, under various constraint conditions, such as renewable energy installation capacity proportion, dumped energy proportion, loss of power supply probability. Five configuration schemes are compared and analyzed. Finally, sensitivity analysis is used to investigate the effects of some system parameters on optimization results.
