This paper presents an algorithm for the selection of corrective control actions for bus voltage and generator reactive power in a power system. A genetic algorithm (GA) using linear approximation of load flow equations and a heuristic selection of participating controls were combined in a search method for the minimum number of control actions. The calculation time in this method was proven to be small enough to allow real-time application of the algorithm. The GA was compared with a integer programming-based solution method and showed a considerably reduced calculation time. The results show that the heuristic method of pre-selecting a set of control devices, together with the GA for finding the ultimate set of required control actions, produce a sufficient solution to the voltage/reactive power problem.
