Title
Multi-Level Power-Imbalance Allocation Control for Secondary Frequency Control in Power Systems.
Abstract
This paper focuses on secondary frequency control of large-scale power systems. First a centralized and a consensus control based distributed control law are presented, then a multi-level control law, named Multi-Level Power-Imbalance Allocation Control (MLPIAC), for the large-scale power systems partitioned into more than one region. The centralized and distributed control law are applied within each region and over the regions respectively. Besides restoring nominal frequency with a minimized control cost, MLPIAC also considers the transient behavior of the system after a disturbance. We present a control strategy different from the one applied in the Power-Imbalance Allocation Control (PIAC), which also enhances the transient behavior of the frequency through an accelerated convergence of the control inputs eliminating overshoots in MLPIAC. In the level of the distributed control over the regions, the consensus of the marginal costs can be accelerated through a single parameter. Furthermore, because the number of regions is smaller than that of nodes, MLPIAC is more effective to obtain the minimized cost than the purely distributed control law. The asymptotic stability of MLPIAC is proven using the Lyapunov method and the performance is evaluated through simulations.
