Fuzzy linear programming approach to the reactive power correction in electrical power systems

In the planning and operating of an electric power system, the voltage magnitudes of the buses are desired within acceptable limits during different operations. The reactive power correction may be used to keep voltages within its limits. In this study a fuzzy linear programming approach is proposed to solve the problem which is to determine the amount of reactive power correction installed in the candidate load buses to maintain voltage levels of all load buses. The proposed approach in which the objective function and the constraints are modeled by fuzzy sets is applied to an example system and the results are given.
