Decomposition-Coordination Research of Reactive Power Optimization for Provincial Grid
Automatic voltage control receives more attention because of the need for total optimization of power grid.The realization of AVC needs coordination and unification of subarea control in the same voltage grade and interlayer control of different voltage grade.According to the characteristics of subarea control and interlayer control of AVC,the reactive power optimization based on the principle of decomposition coordination in provincial grid is proposed to better improve the astringency of algorithm,calculation speed and disposal of discrete variables.
