This article proposes an economic model predictive algorithm for optimal load frequency control, in which both the frequency regulation and economic load dispatch (ELD) are considered, in interconnected power systems. Two-layer hierarchical control can be achieved through one level by EMPC. An economic stage cost function, including ELD and frequency regulation, which can be written in general convex form, is optimized by the controller. The distributed way is utilized to realize the control of large-scale power systems. Each subsystem-based controller works cooperatively with neighboring subsystems to achieve system-wide control performance. Asymptotic stability of the system is guaranteed by the proper terminal cost function. The efficiency and advantages of the proposed method are manifested by the simulation.

基于分布式经济MPC的网络电力系统最优负荷频率控制

本文提出了一种用于最优负载频率控制的经济模型预测算法，该算法考虑了互连电力系统中的频率调节和经济负载分配（ELD）。EMPC可以通过一级来实现两层分层控制。控制器可以优化经济阶段成本函数，包括ELD和频率调节，这些函数可以用一般的凸形形式编写。利用分布式的方式来实现对大型电力系统的控制。每个基于子系统的控制器都与相邻子系统协同工作，以实现系统范围的控制性能。适当的终端成本函数可确保系统的渐近稳定性。仿真结果表明了该方法的有效性和优势。
