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。
Aiming at the influence that the high penetration rate of distributed power sources brings to the stable operation of the distribution network,a method was proposed to analyze the coordination and optimization of voltage and reactive power on the demand side by adding demand response.Based on the models of interruptible and translatable loads,etc.,a voltage and reactive power coordination and optimization model for distribution networks was established.The second-order cone method was used to linearize the original mixed-integer nonlinear model,and a mixed-integer second-order cone programming model was established.The effects of voltage and reactive power and the stability of the electrical network before and after the demand response were analyzed.The results showed that the model could effectively absorb distributed energy,improve energy efficiency,reduce system operating costs,and significantly improve voltage.
