基于汇聚效应的风电集群接入与区域电网协调规划研究
Coordinated planning of wind farm cluster access and regional grid based on convergence effect
摘要
Abstract
One of the important reasons for the difficulty of wind power dissipation is the inconsistency between wind power cluster access planning and regional grid access.On the one hand,the access capacity and access mode of wind power are mutually coupled with the main grid and the layout and operation mode of conventional power sources,which affect the o-verall economy and the effect of wind power dissipation;on the other hand,the whole power fluctuation characteristic of wind power cluster is different from that of single wind farm,which affects the planning.In this paper,the operation con-straints of unit start-up and shut-down are considered to minimize the sum of investment cost,operation cost,abandoned wind cost and lost load cost,based on the relationship between"zero-output probability of wind farm cluster"and"con-vergence capacity",a mixed integer model for coordinated planning of wind farm cluster access and regional grid is estab-lished by simulating the convergence process of wind farm clusters of different scales.And the optimal overall planning scheme is realized under the condition of maximum wind power and system security.Finally,an example is given to illus-trate the effectiveness of the proposed model and method.关键词
