An implementation scheme of coordinated automatic voltage control for provincial power networks

An implementation scheme of coordinated automatic voltage control (AVC) for provincial power network was discussed in this paper. Based on the sensitivity analysis, an optimal power flow(OPF) model for coordinated secondly voltage control(CSVC)was proposed. At the same time, a solving method, which can consider different constraints, was provided. Finally, the results of central bus voltage calculation and the conclusion of power network loss analysis based on the model of coordinated control were derived. The results indicate that the model of coordinated voltage control can improve the economic profit and security of power network.
