摘　　要：提出一种基于混储/柴的专家协调控制系统和算法。目的是在研究混合储能和微网中可调度单元在相同容量下,与传统单一储能和其他调度单元策略对比,以最大化微电网整体运行经济性和延长储能寿命。模型对比传统含单一储能协调控制策略,拟定负荷波动指标,将微网调度分为上层决策和下层实时调度,求解微网可调度单元的合理组合运行方式。采用费用折算耦合微网运行成本、环境效益和储能寿命量化为单目标函数,结合分阶段优化算法和自适应遗传算法求解。通过对实际算例分析,验证了该方法能有效提高电池使用效率,延长寿命,同时提高微网整体运行的经济性。A new coordinated operation expert system and algorithm of hybrid energy storage and dispatchable generation is proposed. The purpose is to maximize the operating economy and prolong the battery＇s lifetime, compared with the conventional cooperation model of single energy storage and dispatchable unit. Considering the running characteristics of hybrid energy storage and diesel generator, the dispatching of microgrid can be divided into upper level decision and lower real-time scheduling, then the reasonable combination operation mode of dispatchable unit is calculated. Depending on the equivalent cost, the microgrid operation costs, environmental benefit and energy storage life of quantitative are converted to a single objective function. Then improved hierarchical heuristic method and employed adaptive genetic algorithm（AGA） are used to optimize the power resources. The example shows that the system can effectively improve the efficiency of battery, prolong battery＇s life and enhance the microgrid operation economy.
