Distributed Cooperative LFC Protocols for Regulation Synchronization for Networked Multi-area Power Grid Networks

In this paper, we propose consensus based distributed cooperative LFC schemes for leader-less networked multi-area power grid network systems in the presence of uncertainty. The LFC schemes design combine local states with the states of the neighboring area with directed communication topology. We propose two distributed cooperative LFC schemes. First, robust LFC schemes are designed by assuming that the bounds of the uncertainty associated with the power network dynamics are available. Then, we remove the demand of the bound on the uncertainty from LFC schemes by designing robust adaptive learning algorithm. Robust adaptive control terms uses to deal with the presence of uncertainty associated with the power networks and external fault disturbance. Lyapunov and graph theory uses to show that the proposed distributed cooperative design can reach an agreement with control areas and solve regulation synchronization problem. Analysis shows that the state of the control areas can reach an agreement and ensure both finite-time and asymptotic consensus property. Evaluation results on a four-area interconnected power grid networks are presented to show the effectiveness of the proposed consensus based distributed LFC algorithm for real-time applications.
