dc.description.abstractThe widespread integration of converter-fed renewable energy sources (RESs) and supported by energy storage systems (ESSs), along with their associated challenges, is causing a pressing need to reconsider the operation of distribution networks. Microgrids (MGs) appear as a practical solution to accommodate these RESs and ESSs. This thesis conducts an in-depth analysis of the design and modeling of a generic MG that integrates RESs and ESSs, incorporating a fuzzy logic controller (FLC)-based energy management system (EMS). The MG operation is evaluated in both grid-connected and islanded modes. A frequency analysis reveals that the point of common coupling (PCC) frequency is controlled within the operational range of ± 0.3 Hz, according to IEEE Standard I547. This control is achieved using a combination of battery and supercapacitor ESS in both operational modes. A comparative evaluation of Proportional Integrator (PI) v/s Proportional Resonant (PR) controllers for current controllers for the MG to reduce the amount of total harmonic distortion (THD) at PCC is conducted. Dynamic testing of MG is also conducted under various loading conditions, encompassing small-, medium-, and large-signal changes. The results prove that the PCC voltages are effectively kept within the typical range of ± 0.05 pu through the FLC-based EMS.
