Due to their intermittent features and poorer inertial response, distributed energy resources (DERs) such as photovoltaic (PV) systems and fuel cell systems have increased the complexity of the power system. This reorganization of the power system has a significant impact on the system's transient responsiveness, resulting in inter-area oscillations, less synchronised coupling, and power swings. Furthermore, the idea of being dispersed and generating electricity from many points in the electrical system exacerbates the transitory impact of DERs by introducing difficulties like reverse power flows. This technique proposed the effects of changing power system characteristics that are impeding large-scale DER integration. In addition, by introducing virtual inertia to inverter-based DERs in the electricity system, a method to enhance the system's inertial responsiveness is addressed. The suggested control increased the stability margin and allowed the system to follow its rated frequency. By increasing the rate of change of frequency, the injected synchronized active power to the system avoids the protective relays from tripping. The suggested system functioning is tested experimentally using the MATLAB 2015 simulation system on a sample power grid that includes generation, transmission, and distribution with solar pv and fuel cell system integration.
