Abstract ：To deal with the concept of direct solvable harmonic power flow with the optimal configuration of PMU, a new algo- rithm based on niche genetic algorithm and Tabu search is presented. The hybrid optimization algorithm takes niche genetic algo- rithm for main part, controls prematurity and solves the lack of diversity; uses TSR operator in crossover to improve local search ability and convergence speed. The effectiveness and contrast between the hybrid algorithm and the other two traditional meth- ods are verified. The results show that this hybrid algorithm can find the optimal solution, and provide understanding of the diversity and improve the optimization efficiency, has broad application prospects.
