Solving multi objective ORPD problem using AIS based clonal selection algorithm with UPFC

الملخص EN

In this paper, a solution for the multi objective optimal reactive power dispatch problem by using an artificial immune system (AIS) based clonal selection algorithm was presented.

The proposed AIS based clonal selection algorithm uses cloning of antibodies and followed by hyper maturation to minimize the voltage stability index (L-index), voltage deviations at all load buses and the transmission real power losses by incorporating the multi type FACTS device namely the UPFC.

The proposed algorithm also uses concepts of non dominated sorting and crowding distance comparison procedures to solve the multi objective optimization problem.

Finally, a fuzzy decision maker strategy is applied to find the best compromise solution.

The algorithm was implemented and tested on two standard IEEE 30-bus and 57-bus test systems with UPFC.

The proposed results are compared with and without placing the UPFC by considering two objectives for optimization.
