两区域重叠互联电力系统分散LQ最优控制方法的改进

Improved approach to decentralized LQ optimal control design for two-area overlapping interconnected power systems

利用系统包含原理的约束类条件和LQ最优控制算法,对两区域重叠互联电力系统提出了以两个单区域子系统为基础的分散控制,并基于稳定度设计策略及遗传算法对该方法加以改进.以两区域重叠互联电力系统19阶线性状态空间模型的负荷频率控制为例,给出了用该方法的设计仿真结果.

By means of the restriction conditions of the system inclusion principle and LQ optimal control algorithm,a decentralized control based on the two single-area subsystems is proposed for two-area overlapping interconnected power system .The method is improved by means of stability design and genetic algorithms.With the load-frequency control of 19-order linear statespace model for the two-area overlapping interconnected power system as an example,the simulation results for this method are presented.
