Distribution of Optimum Reactive Power in the Presence of Wind Power Plant and considering Voltage Stability Margin using Genetic Algorithm and Monte Carlo methods

Abstract

Network reactive power resources are important factors affecting voltage stability that somehow can have effect on safety margin of system voltage stability. In this study, question of relationship between distribution of optimum reactive power and voltage stability margin in presence of wind power plant has been performed. For this reason, to minimize the reactive power costs due to the synchronous generator, synchronous condenser and the capacitor bank and also given the importance maximization the voltage stability margin and considering equality and inequality constraints, has been used from a nonlinear programming method. In here, problem by using Genetic Algorithm in order to minimize cost of reactive power and with considering the voltage stability margin based on Monte Carlo simulation method. In MATLAB software has been optimized. Problem simulation over 30-bus network has been solved for two state low load and full load and with two scenarios was run and analyzed.
