基于系统聚类法的含新能源电力系统分区策略
Partitioning Strategy for Power System Containing New Energy Based on Systematic Clustering Method
摘要
Abstract
To effectively evaluate the inertia distribution characteristics of a power system containing new energy,a par-titioning strategy based on the systematic clustering method is proposed.First,the difference between the inertia of the new energy unit and that of the synchronous unit is analyzed.Second,a node inertia response model is constructed to analyze the characteristics of factors related to the node inertia.Third,the principal component analysis method is used to reduce the dimension of dominant variables that affect the node inertia.After the dimensionality reduction,the sys-tematic clustering method is applied to cluster and partition the nodes.Finally,the regional inertia is obtained by sys-tem identification,and the spatial distribution of the inertia of the whole system is evaluated.An improved IEEE 10-ma-chine 39-node model is built in the simulation software,and results verify the rationality of the proposed partitioning strategy.关键词
