摘要

为有效聚合电网需求侧资源,合理、高效利用电网资源,提出基于分布式k-means的电网需求侧资源动态聚类算法.通过基于置信半径的分布式k-means算法聚类采集到的电网需求侧资源数据,在模糊C均值进化神经网络中,以聚类得到的电网需求侧资源数据为输入向量,输出电网需求侧资源场景,依据场景存在概率,以电网侧资源日均峰谷差最小、DG消纳程度最高与日均负荷波动率最小为目标函数,以电网需求侧资源曲线波动率与负荷互补为约束条件,构建电网需求侧资源多场景聚类模型,经动态改变惯性因子(DCW)粒子群算法求解模型后,实现电网需求侧资源多场景聚类.试验结果表明:该方法可实现电网需求侧资源动态聚类,应用该方法聚类不同场景电网需求侧资源时的日负荷率较低,聚类效果较好,可满足实际电力需求侧资源动态聚类工作的需要.

Abstract

In order to effectively aggregate power grid demand side resources and make rational and efficient use of power grid resources, a dynamic clustering algorithm of power grid demand side resources based on dis-tributed k-means is proposed. The collected power grid demand side resource data are clustered by the distrib-uted k-means algorithm based on the confidence radius. In the fuzzy mean evolutionary neural network, the power grid demand side resource data obtained by clustering is used as the input vector to output the power grid demand side resource scenario. According to the scenario existence probability, the daily average peak valley difference of power grid side resources is the smallest taking the maximum consumption degree and the minimum daily average load fluctuation rate as the objective function and the complementarity of power grid demand side resource curve fluctuation rate and load as the constraint conditions, a multi scene clustering model of power grid demand side resources is constructed. After the model is solved by dynamically changing the inertia factor (DCW) particle swarm optimization algorithm, the multi scene clustering of power grid de-mand side resources is realized. The experiment results show that this method can realize the dynamic cluste-ring of power grid demand side resources. When this method is used to cluster power grid demand side re-sources in different scenarios, the daily load rate is low, the clustering effect is good, and can meet the needs of dynamic clustering of power demand side resources.
