Abstract A mathematical formulation considering both medium and low voltage optimal reactive power compensations is built for the distribution networks. A solution method based on genetic algorithm is then proposed. The formulation and the solution method can deal with multiple load levels. The capacitor sizes and their number of banks are optimized simultaneously. In order to evaluate configurations of the compensating capacitors, a procedure to simulate the switching on/off of each capacitor is designed. The candidate places for compensation are selected based on sensitivity analysis and the loss reduction index of per unit investment. The searching space of the proposed method is greatly reduced by choosing effective candidate places first. Numerical tests show the effectiveness of the proposed method.
