PROJECT TITLE :
Decentralized Optimal Frequency Control in Autonomous Microgrids
For frequency regulation and accurate active power sharing in self-sufficient microgrids, this study presents a decentralised, optimal secondary controller. There is no need for a Communication network with this ideal controller. The linear quadratic regulator (LQR) method, in contrast to most previous research, introduces a systematic approach to secondary controller design based on a quadratic cost function. Power calculation filter cut-off frequency dictates the design approach. The key advantages of this approach are its decentralisation, simplicity, optimality based on a quadratic cost function, and straightforward design procedure. It is not necessary to use an event-driven or time-dependent procedure to restore frequency immediately after a disturbance occurs with the proposed method. The effectiveness of the proposed controller has been demonstrated in experiments.
