| 摘 要： | 电力系统电压控制是维持系统电压水平的重要环节.文中基于模型预测控制理论和方法,利用分解协调法及辅助问题原理构造了分布式电压协调控制模型,实现了电压预测控制模型及结构的分解,使全局集中的优化问题转化为若干个只需本区域系统模型及数据的可分布式协调求解的子优化问题,有效降低了优化问题的求解规模,提高了计算和控制的灵活性及安全性.仿真结果表明,该方法能有效地控制系统电压,防止电压失稳,获得与集中电压预测控制相似的控制效果.

| Abstract: | Voltage control of power systems is one of the key links in maintaining the power system voltage level.Based on the model predictive control(MPC) theory and method,a distributed control model and structure are obtained by employing the decomposition-coordination technology and the auxiliary problem principle to realize the decoupling of the mathematical model and structure of voltage predictive control.Thus the global centralized optimization problem is decomposed into some sub-problems that are only relate... |
