Impact of wind power generation on ATC calculation with uncertain equal load

Available transfer capability (ATC) is very important for system operators for a fair and transparent electricity market. There are many methods to calculate and to improve the ATC value in the power system. Due to green energy focus across the globe, renewable energy integration to the system to improve the ATC value need to be established. Lots of literature have been published on wind power integration to improve ATC value using active power support. During highly loaded conditions, reactive power plays an important role. In this paper, active as well as reactive power of wind turbine generation for ATC calculation has been considered. The reactive power limit has been considered based on the capability curve of the wind turbine generator. Real-time wind speed data for wind power output calculation are taken. The impact analysis of wind power generation on ATC variation under normal as well as contingency cases has been carried out. The effectiveness of the proposed method is tested on the IEEE-30 bus system.
