Contingency constraint corrective rescheduling with the presence of wind farm

This paper describes the impact of wind generation to enhance the power system security level following a line contingency. In this formulation, fixed speed wind turbine generating unit (FSWTGU) is used. A contingency analysis (CA) and ranking process is used to determine the most severe contingency considering line overloads and bus voltage limit violations. The optimal power flow (OFF) model and contingency constraint optimal power flow (CCOPF) model with FSWTGU are developed. The FSWTGU is modelled as PQ bus in investigating its impact on power system security analysis. An artificial bee colony (ABC) based optimization algorithm is used for solving the OFF model. The proposed algorithm was tested on IEEE-30 bus system. In order to validate the results obtained, the same CCOPF has been solved without the presence of wind farm. The obtained results show the effectiveness of wind farm to enhance the security margin of power system.
