Fuzzy-Based Distributed Cooperative Secondary Control with Stability Analysis for Microgrids

This research suggests a novel distributed cooperative control methodology for secondary controller in islanded microgrids (MGs). The proposed technique not only brings back the frequency/voltage to its reference values, but also maintains precise active and reactive power-sharing among generation (DG) units by means of sparse communication system. Due dynamic behaviour (DSC), stability issues are great concern networked MG. To address this issue, analysis is undertaken systematically, utilizing small-signal state-space linearized model considering DSC loops parameters. As creates new oscillatory modes, an intelligent fuzzy logic-based parameter-tuner enhancing system stability. Accurate tuning parameters can develop functioning system, which increases MG greater extent. Moreover, performance offered method proved conducting widespread simulation several case scenarios MATLAB/Simscape platform. addresses nature supporting plug-and-play functionality, working even fault conditions. Finally, convergence comparison study shown.
