摘　　要：针对用户侧储能容量规划问题,分析用户侧典型负荷曲线提取方法的差异对储能容量配置结果的影响,考虑储能减少用户电量电费支出、降低配电站容量需求、延缓设备改造与扩容、节省耗煤量、减少污染物排放等直接、间接效益和储能全寿命周期成本的基础上,建立储能容量优化规划数学模型,并采用遍历算法结合非线性优化进行求解。以年负荷数据配置储能容量为基准,对比分析不同典型负荷曲线下储能容量配置的差异。结果表明：系统收益构成、电力市场政策、储能激励机制、负荷曲线特性等因素影响典型负荷曲线的选取,文中算例条件,以月度最大日负荷作为典型负荷曲线配置储能容量与实际结果具有较大的一致性。Aiming at the problem of energy storage capacity configuration in the user side,the effect of divergence of extraction method of typical load curve in user side on energy storage capacity configuration is analyzed.The mathematical model for optimal planning of energy storage capacity is established based on considering the direct and indirect benefits of energy storage,such as reduction of electricity bills for users,reduction of capacity requirements of distribution stations,delay of equipment modification and capacity expansion,savings of coal consumption,reduction of pollutant emissions etc whole life cycle cost of energy storage,and using the traversal algorithm and nonlinea roptimization to solve.Configuring energy storage capacity based on annual load data,the differences in energy storage capacity configuration under different typical load curves are compared and analyzed.The results show that system’s revenue structure,electricity market policies,energy storage incentives mechanism,load curve characteristics etc affect the selection of typical load curves.Based on example calculation condition,there is greater consistency with actual results for energy storage capacity configuration by taking monthly maximum daily load as typical load curve.
