The reactive power source planning problem has a significant influence on secure and economic operation in electric power systems. To achieve both goals, system maximum security and minimum cost in operation, reactive power planning is posed as a multiobjective optimisation problem in terms of mathematical language. In the paper, the authors present an effective algorithm based on hybrid expert system simulated annealing (ESSA) to circumvent the complicated planning problem. A more practical problem formulation with multiobjectives and constraints is presented. Then, ESSA is introduced to search the global optimal solution considering both quality and speed at the same time. Simulation cases are used to evaluate the proposed algorithm
