含风电场的电力系统动态关键输电断面分析
Dynamic Key Power Transmission Sections of Power Systems Integrated with Wind Farms
摘要
Abstract
Accessing of large-scale wind farms to high voltage power transmission grids will have greater effect on electric en-ergy transmission and distribution,it is necessary to study key power transmission sections considering output characteristics of wind farms. By means of bringing dispatching plan into power grid analysis and introducing probability distribution func-tions of wind speed and load forecast errors to describe uncertain factors in the system,a kind of automatic analysis algo-rithm for power grid division and key power transmission sections based on probabilistic load flow (PLF)analysis and com-plex network theory is proposed to establish an analysis model for dynamic key power transmission sections for considering flexibility of power grid dispatching operation. On the basis of PLF analysis,power transmission betweenness considering uncertain factors is presented for line identification. And then,based on analysis for small world characteristics of power grids,Girvan Newman algorithm is used for power grid division clustering so as to find out key power transmission sections and sort their importance. Simulation calculation on CEPRI 36 node system integrated with wind farms verifies effectiveness and practicability of this model and algorithm as well as explains features of power transmission sections of power systems in-tegrated with wind farms.关键词
