Optimization method of VSC-MTDC network for offshore wind farms cluster considering voltage stability constraints
摘要
Abstract
The offshore wind farms will toward into the deep sea and clustering direction,voltage source converter based multi-terminal direct current(VSC-MTDC)shows advantages for long-distance,large-scale offshore wind power system,it is necessary to research the optimization method of VSC-MTDC network for offshore wind farm cluster.Considering that the aggregation effect of wind farms cluster will affect the capacity of electrical equipment and the influence of the voltage sta-bility of point of common coupling(PCC)on the access capacity of large-scale wind power.This paper derives a PCC voltage stability index,introduces the concept of"N+"criterion to configure the capacity of electrical equipment,and proposes an optimization method of VSC-MTDC network of offshore wind farms cluster considering voltage stability con-straints and"N+"criterion.The improved NSGA Ⅱ algorithm is used to analyze the offshore wind farms cluster.The ex-ample results show that the capacity allocation according to"N+"criterion has the best economic efficiency,and the PCC voltage stability constraint can improve the voltage stability of the PCC,although it will increase the investment.关键词
