从输电阻塞角度建立的风电场容量可信度模型
Wind-farm capacity-credit model considering transmission congestion
摘要
Abstract
Both reliability and transmission congestion should be considered when a wind farm is connected to a power system.Nevertheless,wind-farm capacity credit (CC)is defined currently considering reliability only.In this work,we proposed a wind-farm CC definition based on transmission congestion,built a CC model taking into account the random failures of power system components (generating units,transmission lines and transformers)using Monte Carlo technique,and proposed a solution algorithm of CC model using the bisection method.We also proposed wind power congestion indices to describe the contribution of a wind farm incorporated into a power system to alleviating transmission congestion.The case studies on a modified IEEE-RTS indicate that the proposed method is effective and feasible.The results show that for a power system,alleviation of transmission congestion is related to the wind-farm location,the combination of CC and wind power congestion indices can evaluate the effectiveness and economical efficiency of a wind farm in alleviating transmission congestion.关键词
