Abstract
High integration of wind power generation is expected into electric power grid to meet the energy sustainability and security requirement supported by federal policies and state renewable portfolio standards. However, the presence of such renewable sources in the transmission and distribution networks need to be analyzed by sufficient system impact studies to ensure reliability of power supply. The associated influence of these technologies can easily affect the existing volt/VAr management schemes. Advanced wind generator units are capable of providing additional volt/VAr support to the grid due to their advanced power electronic interfaces. These can be operated in power factor control mode, voltage control mode and voltage regulating mode. Recent research and utility case studies have justified the need for additional VAr support in the network during normal and emergency operating conditions. Different management schemes must be formulated in order to v operate the transmission and distribution systems to meet their unique goals based on the operational objectives, network topologies and control mechanism. As a part of this work, coordinated volt/VAr management schemes are developed for the transmission and distribution network. Based on the lessons learnt from the Western Electricity Coordinating Council Regional Transmission Expansion Planning project, coordinated volt/VAr schemes are developed that optimize the transmission system loadability considering the voltage stability margin and utilizing Flexible AC Transmission System devices and wind generators reactive power capability.
