摘要
在配电网发生计划停电的情况下,基于云储能的家庭微电网进入孤岛运行状态,考虑到云储能用户可用储能容量有限以及可再生能源出力的不确定性,提出应急能源管理策略以减小用户停电损失和用户不满意度。首先,将云储能分为供电储能和交易储能,供电储能的容量可以保证计划停电期间用户重要负荷的供电;其次,以减小用户停电损失和用户不满意度为目标建立应急能源管理模型,引入权重因子以衡量二者的重要程度,然后采用遗传算法对模型进行求解,得到的最优解即为用户的应急能源优化调度方案;最后,通过实验仿真对比验证了所提优化策略能够有效减小用户停电损失,同时降低用户不满意度。
In the case of planned power outage in the distribution network,the home microgrid based on cloud energy storage enters the island operation state.Considering the limited available energy storage capacity of cloud energy-storage users and the uncertainty of renewable energy output,the strategy of emergency energy management is proposed to reduce user’s power outage loss and user dissatisfaction.Firstly,the cloud energy storage is divided into power storage and transaction storage.The capacity of the power storage can ensure the power supply of user’s important loads during the planned power outage;Secondly,the emergency energy management model is established with the goal of reducing user power outage loss and user dissatisfaction,and the weight factors is introduced to measure the importance of the two.Then the genetic algorithm is used to solve the model,and the optimal solution is the optimal scheduling scheme for user’s emergency energy.Finally,it is verified through experimental simulation that the proposed optimization strategy can effectively reduce user power outage loss and user dissatisfaction.
