摘　　要：为应对分布式能源波动性大、抗干扰能力较弱的问题,探索以分布式能源供电为主的独立微网综合资源配置意义重大。建立了含可中断负荷的独立微网综合资源规划优化模型,将可中断负荷的最大调用容量和分布式电源装机容量同时进行优化规划,以更好地发挥可中断负荷在独立微网中的作用,提高微网运营经济性;应用聚合机组模型等多种线性化建模方法将所建立的模型线性化,调用CPLEX求解器的混合整数线性规划法对线性化后的模型进行求解;通过仿真计算验证了所建立模型和采用方法的正确性,并从计算结果中得出可再生能源占比较高的独立微网中可控电源和可中断负荷的容量规划策略。In order to cope with the problems of high volatility and weak anti-interference ability of distributed energy sources,it is significant to explore the integrated resource allocation of independent microgrids mainly powered by distributed energy sources.An integrated resource planning optimization model for independent microgrids containing interruptible loads is established,and the maximum calling capacity of interruptible loads and the installed capacity of distributed generation are optimized and planned at the same time,so as to better play the role of interruptible loads in independent microgrids and to improve the economics of microgrid operation;multiple linearization modeling methods,such as the aggregated unit model,are applied to linearize the established model,and the mixed-integer linear optimization method of the CPLEX solver is called to solve the linearized model.The correctness of the established model and the adopted methods are verified through simulation calculations,and the capacity planning strategies for controllable power sources and interruptible loads in independent microgrids with a high share of renewable energy are derived from the calculation results.
