Abstract
In a Micro-Grid (MG), substantial-frequency fluctuations are caused by the sporadic nature of Renewable Energy Sources (RESs). Conventional Integral controllers are incapable of delivering adequate performance against the widely varied operating conditions. Hence, in this paper, the Fuzzy Logic-based Integral controller & Superconducting Magnetic Energy Storage (SMES) unit are incorporated in isolated MG to mitigate the frequency control issues. As a result of rapid changes in load and the discontinuous nature of RESs, frequency oscillations are produced, which are dampened by SMES units. The simulations are done in MATLAB / Simulink software. The results of the simulation reveal that the LFC system with a Fuzzy logic-based Integral controller and SMES unit has greater dynamic performance when compared to other LFC systems (with & without SMES unit using conventional Integral controller).
