基于改进加权Voronoi图算法的有源配电网变电站规划
Substation Planning of Active Distribution Network Based on Improved Weighted Voronoi Diagram Method
摘要
Abstract
Faced with the situation of large-scale access to distributed generator (DG) and various load characteristics, a substation planning method of active distribution network based on the improved weighted Voronoi diagram method is proposed.Firstly, load characteristics are introduced to the evaluation of DG capacity credit, and the influence of load and DG output characteristics on DG capacity credit is analyzed.Secondly, with the DG capacity credit taken into account, a substation planning model of the active distribution network is developed.Thirdly, two improved weighted Voronoi diagram methods are adopted to solve the model.By adjusting the weight according to the situation of power supply range expanding at each iteration, the hierarchical improvement of weighted Voronoi diagram method is archived.By steadily adjusting the weight according to the power supply range consistency of substation and DG, a directional improvement of the weighted Voronoi diagram method is archived.Finally, an example is used to show the scientific and practical merits of the proposed method.关键词
