Combined Heuristic and Evolutionary approach for Reactive Power Planning Problem

In this paper authors have used mixed heuristic and evolutionary technique for solving the reactive power problem. In doing so, power system control variables are treated as planning & dispatch variables. All the variables of the reactive power optimization problem do not involve cost. The variables which does not involve cost treated as dispatch variable and those involve cost are treated as planning variable. Heuristic method is used for installation of capacitor’s on weak buses and evolutionary programming approach is used for setting of transformer tap positions and reactive generations of the Generator’s.
