Considering the randomness of wind power 证了该方法的有效性。 generation, a chance-constrained programming based capacity 关键词：微网；混合储能；机会约束规划；模糊控制 configuration method and a corresponding model for hybrid energy storage system (HESS), in which the constraints of both 0 引言 power output of an HESS and state of charge (SOC) are 由于能源危机和环境约束，微网越来越引起人们 considered and the minimum cost of HESS is taken as 关注，根据美国电力可靠性解决方案协会定义，微 objective, are proposed. The proposed model is solved by genetic algorithm and the relation between the confidence 网的特点是功率 10MW 以下，由多种分布式发电单 degree of wind power fluctuation that does not overstep a 元、储能单元、负荷及控制装置组成。由于微能源具 certain interval and the cost of optimal configuration of HESS 有随机性和间歇性，因此孤岛状态下微网的能量平衡 is obtained, thus a quantitative basis to appropriately 是微网的核心问题之
