The generator excitation system adjustment coefficient determines the reactive power control features of the generator. Reasonable setting of the excitation system adjustment coefficient can improve the reactive power support capacity of the generator to the regional power grid. In this paper, we propose a reactive power optimal planning model, which takes into account the generator excitation system adjustment coefficient, fully exploit the reactive power voltage control capacity of the generator in the reactive power optimal planning and utilize the Benders decomposition algorithm to work out an optimized solution. Results of grid simulation show that the proposed method can improve the grid voltage level and reduce the comprehensive operating costs of the power grid.
