Generator rescheduling for congestion management with incorporation of wind farm using Artificial Bee Colony algorithm

Abstract

Power system congestion is a major problem for independent system operator (ISO) in a deregulated environment as it violates system security and cost. So it is an important task for ISO to maintain congestion free power system. In this paper generator rescheduling technique has been adopted with incorporation of wind farm in the system. Present work is three folded. Firstly location of wind farm is selected based upon power transfer distribution factor (PTDF). Secondly generator sensitivity factor (GSF) has been determined to reduce number of participating generator in congestion management. Thirdly selected generators have been rescheduled using Artificial Bee Colony (ABC) optimization techniques to mitigate transmission congestion. The proposed method is applied on IEEE 39 bus New England test system.
