关键词电压无功优化控制地区电网集散协调控制混合遗传算法 I Abstract The power system has grown rapidly in recent years, which adds plexity of control. At the same time, users require better voltage quality and adequate security. In addition, economic issues have to be considered for the power system itself. Thus, the control of a power system is a multi-objective global optimization problem that requires more effective and robust strategies. The main task we should face now is to make a way out of how to enhance the control level in the existing conditions, to improve the voltage quality, and to make the power system operated under the optimal state. The basic concept and principle are introduced systemically. After reviewing kinds of schemes for voltage and reactive power control (VQC), a scheme and its model of optimal coordinated-correlative control for the regional power system is developed based on the home actuality of VQC. The scheme has a two-level structure, which can neatly realize optimal coordinated control and can disperse the responsibilities of control. When it is permitted by the conditions, a scheme of centralized optimization may be used, for it can realize global optimal control theoretically. The corresponding idea and the frame for regional power system are provided with the model.
