Volume : III, Issue : VIII, September - 2013 A Multi Objective Differential Evolution approach for optimal Reactive Power and Voltage Control D.Godwin Immanuel , G. Selva Kumar And C.Chritober Asir Rajan Published By : Laxmi Book Publication Abstract : Reactive power and voltage control is very essential for the proper operation and control of power system. This paper presents an efficient Differential Evolution approach to solve multi objective and multi constrained reactive power and voltage control problem. The objective functions are minimization of real power losses, minimization of voltage deviation and minimization of voltage stability index for the most vulnerable bus. In this approach the generator voltages, the transformer tap changers and the switchable VAR sources are taken as the control variables to get the optimal solution. The effectiveness of the proposed system has been tested in standard IEEE 30 bus test system it satisfies all the equality and inequality constraints and successful results have been obtained.
