摘要:: 针对分布式电源的高渗透率对配电网的稳定运行带来的影响，提出通过加入需求响应来分析需求侧对电压无功协调优化的方法。根据可中断可转移负荷等模型建立了计及需求响应的配电网电压无功协调优化模型；并采用二阶锥方法将原始混合整数非线性模型线性化，建立混合整数二阶锥规划模型；分析需求响应前后对电压无功及电网络稳定的作用。结果表明：建立的模型可有效消纳分布式能源，提高能源利用率，降低系统运行成本并对电压有明显的改善作用。

Abstract:: Aiming at the influence of the high penetration rate of distributed power generation on the stable operation of distribution network, a method of analyzing the coordination and optimization of voltage and reactive power on the demand side by adding demand response is proposed. Based on the models of interruptible and transferable loads, a distribution network voltage and reactive power coordination optimization model considering demand response is established; and the original mixed integer nonlinear model is linearized by the second-order cone method, and a mixed integer second-order cone programming model is established ; Analyze the effects of demand response on voltage reactive power and grid stability before and after. The results show that the established model can effectively accommodate distributed energy, improve energy utilization, reduce system operating costs and significantly improve voltage.
