However, most re-newable sources, excluding large hydro, have zero or negligible rotational inertia, which is critical to stabilizing the power system after contingency. Therefore, this paper proposes a droop-based inertia emulator to reduce the rate of change of frequency and. . Inertia in power systems refers to the energy stored in large rotating generators and some industrial motors, which gives them the tendency to remain rotating. The tested system consists of a Photovoltaic (PV) based VSG that is connected to a 9-Bus grid and the simulation. . Energy storage systems (ESSs) can be used to mitigate this problem, as they are capable of providing virtual inertia to the system. This paper proposes a novel analytical approach for sizing ESSs to provide inertial support to the grid and maintain frequency stability in presence of RERs. This. . Integration of clean energy sources reduces the inherent rotational inertia, making the system precarious and susceptible to various disturbances.
