Optimal Reactive Power Dispatch Problem Solved By Using Flower Pollination Algorithm

In this paper, a new nature inspired and efficient algorithm based on flower pollination is proposed for solving the optimal reactive power dispatch (ORPD) problem. The proposed algorithm is simple, easy to implement and with less number of parameter to be tuned. ORPD is an important power system optimization problem for improving the stability of the system. Loss minimization objective based ORPD is considered in this paper. Generator bus voltages, transformer tap settings and var output of SVCs are taken as the design variables in the problem. The proposed algorithm is implemented in the standard IEEE-30 bus system and results are compared against the recent literatures. Three different cases are taken for the loss minimization objective. The comparisons show that the algorithm performs better than the other algorithms in terms of solution quality.
