摘要

针对目前在配电网光伏消纳能力评估过程中不能全面考虑电力系统中负荷特性多样化对光伏消纳能力影响的不足,提出一种考虑负荷运行中的实际情况,光伏消纳模拟与概率评估的方法。首先采用支持向量机-随机森林算法对负荷数据进行清洗,再采用改进谱聚类算法对不同类型的负荷特性进行聚类分析,然后基于场景分析法选取不同负荷的类型曲线作为节点处负荷数据,最后基于蒙特卡洛模拟法和均匀抽样法进行光伏消纳方案随机模拟与消纳能力近似评估。基于IEEE 33节点系统算例分析,对有无考虑负荷特性的抽样结果进行对比,有效验证了所述方法的适用性。

Abstract

In view of the shortcomings that the influence of the diversification of load characteristics on the photovoltaic absorption capacity of the power system cannot be fully considered in the process of evaluating the photovoltaic absorption capacity of the distribution network, a method of photovoltaic absorption simulation and probability evaluation considering the actual situation in load operation is proposed. Firstly, the support vector machine-random forest algorithm is used to clean the load data, and then the improved spectral clustering algorithm is used to cluster the different types of load characteristics. Furtherly, the type curves of different loads are selected as the load data at nodes based on the scenario analysis method. Finally, based on the Monte Carlo simulation method and the uniform sampling method, the stochastic simulation of the photovoltaic absorption scheme and the approximate evaluation of the absorption capacity are carried out. Based on the example analysis of IEEE33 node system, the sampling results considering the load characteristics are compared, which effectively verifies the applicability of the proposed method.
