摘　　要：居民用户配置共享储能可以降低储能的配置成本,提高储能带来的套利收益。针对目前居民用户共享储能配置存在的容量冗余问题,提出一种考虑容量削减的居民用户共享储能优化配置方法。首先,以全体居民用户在共享储能全寿命周期内的净收益最大为目标构建共享储能优化配置模型,获取居民用户的充/放电策略;其次,运用统计学原理,对该充/放电策略进行分析,计算居民用户同时充/放电的概率;再次,引入削减比例系数对共享储能初步配置结果进行修正,通过对居民用户的同时充/放电概率进行约束,以计及运行风险成本的共享储能配置成本最小为目标确定最优的削减比例系数;最后,通过算例进行验证,结果表明,所提的共享储能可在传统共享储能的基础上进一步缩减储能配置规模,减少共享储能的配置成本。Shared energy storage equipment on the residential user side can effectively reduce the cost of energy storage and increase the benefits of energy storage equipment.To solve the problem of capacity redundancy in the shared energy storage configuration on the residential user side,this study proposes an optimal method for residential shared energy storage that considers capacity reduction.First,shared energy storage is preliminarily optimized to maximize the net income of all residents in the entire life cycle of energy storage,and the initial charging and discharging strategies of residential users are obtained.Second,the probability of simultaneous charging and discharging for residential users is calculated by analyzing the charging and discharging strategies using statistical principles.Third,a reduction factor is introduced to modify the preliminary allocation results of the shared energy storage.By constraining the simultaneous charging and discharging probabilities of residential users,the minimum allocation cost of shared energy storage,considering the risk cost,is taken as the objective to obtain the optimal reduction factor.Finally,the simulation reveals that the proposed shared energy storage system can further reduce the scale and cost of shared energy storage compared to traditional shared energy storage.
