Hybrid Tabu search-simulated annealing method to solve optimal reactive power problem

Reactive power optimization problem has a substantial inspiration on secure and economic operation of power system. In this work we utilized Hybridized Tabu Search-Simulated Annealing (HTSSA) algorithm to solve reactive power problem. At first both the algorithm separately solved the reactive power problem, then hybridization has been done and the hybridized algorithm has been utilized to solve the reactive power problem. Detailed comparisons have been done between three modes. The validity of the proposed algorithm has been tested in standard IEEE 30 bus system. And the results show the proposed algorithm HTSSA efficiently solved the reactive power problem. Simulation results clearly show that real power loss considerably reduced and voltage profiles also within the limits.
