Abstract: OPTIMAL REACTIVE POWER DISPATCH USING EVOLUTIONARY TECHNIQUES This paper present the application of evolutionary techniques for solving the problem of optimal reactive power dispatch for a single operational point and for a given time interval. This problem could be formulated mathematically as a nonlinear, non smooth, mixed-integer, multi-objective optimization problem. The main objective deals with the minimization of the real power losses and improving the voltage profile across the transport system keeping the control variables in their operational limits. There has been presented theoretical aspects about optimal power flow problems, the Newton – Raphson load flow algorithm and has been presented in detail three evolutionary techniques (genetic algorithms, particle swarm optimization and differential evolutionary algorithm) used for fulfilling the objectives. The three algorithms were implemented in Matlab. Initial it was made a comparison between the three techniques applied on three mathematical functions. After these simulations the best two techniques were chosen (particle swarm optimization and differential evolutionary algorithm) to solve the problem of optimal reactive power dispatch, using four test networks (IEEE 30, Nordic 32, IEEE 118 and IEEE 300). For the problem of optimal reactive power dispatch for a given time interval taking into consideration the number of operations between two successive hours was chosen differential evolutionary algorithm, algorithm tested and validated also on a real electric network (Romanian 220kV and 400 kV network). In conclusion differential evolutionary algorithm has proved that he is a simple but powerful tool for power system optimization problems with nonlinear objectives and constraints and that he is capable of solving the problem of optimal reactive power dispatch for a single operational point and for a given time interval with limiting the number of operations between two successive hours.
