摘　　要：大量分布式光伏接入配电网、引发了电压双向越限、波动和闪变等电能质量问题,影响了配电网的安全稳定运行。分布式储能响应速度快,能快速提供功率支撑,解决电能质量问题。将配电网络根据储能分布位置和节点间的电气距离划分为不同控制区域,以储能收益最大为目标函数,电压不越限为约束,设计了存在电压越限节点的区域的储能调压策略,最后在IEEE 33节点系统进行仿真,验证本方法在解决配电网电压越限问题上的有效性。A large number of distributed PV are connected to the distribution network,causing power quality problems such as bidirectional voltage out of limit,fluctuation and flicker,which affect the safe and stable operation of the distribution network.Distributed energy storage has fast response speed,can quickly provide power support,and solve power quality problems.In this paper,the distribution network is divided into different control areas according to the distribution location of energy storage and the electrical distance between nodes.With the maximum energy storage income as the objective function and the voltage not exceeding the limit as the constraint,the energy storage and voltage regulation strategy is designed for the area where there are voltage exceeding limit nodes.Finally,the simulation is carried out in the IEEE 33 bus system to verify the effectiveness of this method in solving the voltage exceeding limit problem of distribution network.
