摘要

针对未来规划区域面临大规模分布式电源（DG）接入的情况

提出了一种基于DG置信容量评估的有源配电网变电站选址定容方法。首先

从可靠性的角度出发

综合考虑变电站主变压器故障及DG出力的时序特性

根据DG接入前后可靠性指标不变的原则

引入了一种DG置信容量评估方法

然后结合加权Voronoi图算法

提出了一种含DG的变电站选址定容方法。最后

通过对实际算例的对比分析

验证了所提方法的有效性和实用性。

Abstract

In light of the future situation of large-scale access to distributed generators

a substation optimization method for siting and sizing based on the capacity credit evaluation of the distributed generator (DG) is proposed. First

based on the principle that the reliability of the system remains unchanged before and after DG’s access

a capacity credit evaluation method for DG is proposed from the reliability perspective

which takes the transformer fault and the temporal property of DG’s power supply into consideration. Furthermore

with reference to the weighted Voronoi diagram method

a substation siting and sizing method with DG taken into account is proposed. In the end

both the effectiveness and practicability of the proposed method are verified through comparison and analysis of calculation examples. This work is supported by National Natural Science Foundation of China (No. 51477116).
