With the increasing penetration of photovoltaic (PV) generation, challenges have arisen in terms of grid stability due to lack of inertia and damping. The photovoltaic virtual synchronous generator (PV-VSG) was implemented to solve these issues by using a combination of maximum power point tracking (MPPT) and VSG. This article proposes an improved voltage-controlled GFM-PV which implements VSG control with MPPT limit (MPPTL). In the proposed method, PV power is reserved to provide a power buffer for virtual inertia and primary frequency modulation. The proposed control strategy provides grid forming without any energy storage devices. Virtual inertia evaluation is experimentally implemented by a comparison between the proposed MPPTL GFM-PV and the conventional grid following inverter with battery storage system (GFL-BESS) in a 165-kVA microgrid system that contains a 125-kVA diesel synchronous generator.
