摘　　要：为了有效利用分布式风电和开关设备,探索储能系统能给电网带来的最大运行价值,提出一种开关和储能系统协调规划模型。该模型以开关和储能设备的综合成本(包括投资和运行费用、网络损耗、缺电成本和电价收益)最小为目标,计及储能设备的充放电特性和网络安全约束。利用分段编码的遗传线性综合算法确定储能容量和开关位置。IEEE 33节点系统算例的求解结果表明,所提模型能提高系统可靠性和可再生能源利用率,保障系统安全运行。A model for the coordinated allocation of BESS and controllable switches in distribution network is developed to optimize the use of distributed wind generation and switch equipment and to explore the maximum operational value of BESS（Battery Energy Storage System）, which takes the minimum com- prehensive cost as its objective,including the investments ＆ operational costs of switches and BESS,the network loss and the load shedding loss,and considers the charging/discharging characteristics of BESS and the network security constraints. The energy storage capacity and the allocation of switches are calculated by the GALP（Genetic Algorithm with Linear Program） based on segmented encoding. The results of ease study for IEEE 33-bus system show that,with the proposed model,the reliability of BESS and the utilization of renewable energy are enhanced and the operational security of grid is guaranteed.
