摘　　要：由于电力系统在低谷负荷时段的负载水平较低,容易出现潮流拥挤、低电量击穿问题,影响系统的稳定性和安全性。为此,提出基于和声搜索的高需求响应低谷负荷过载控制方法。根据配电网拓扑结构,利用和声搜索算法,求解电信号潮流量的具体数值。提取符合和声搜索算法识别需求的信号参量,将低谷负荷解耦处理,构造过载负荷向量,联合相关电量负荷信号,确定低谷负荷过载行为的控制条件,设计高需求响应低谷负荷过载控制方法。实验结果表明,所提方法高需求响应低谷负荷量不超过3.8 kW·h,不会造成低电量击穿问题,能够较好地维护电力系统的稳定运行。Due to the low load level of the power system in the off⁃peak load period,the problems of power flow congestion and low power breakdown are easy to occur,which affect the stability and security of the system.Therefore,a high demand response off⁃peak load overload control method based on harmonic search is proposed.Based on the topology of the distribution network,the harmonic search algorithm is used to solve the specific value of the electrical signal tidal flow.Extract the signal parameters that meet the identification requirements of the harmony search algorithm,decouple the low valley load,construct the overload vector,combine the relevant electricity load signals,determine the control conditions of the low valley load overload behavior,and design the high demand response low valley load overload control method.The experimental results show that the high demand response and low valley load of the proposed method do not exceed 3.8 kW·h,which will not cause the problem of low power breakdown,and can better maintain the stable operation of the power system.
