Abstract:

The autonomous operation of photovoltaic-based microgrids is strongly reliant on the integration of energy storage systems, notably Hybrid Energy Storage Systems (HESS) that include super capacitors. However, the lack of rotational inertia in PV-HESS power systems can cause undesirable frequency oscillations in reaction to changes in load demand or rapid swings in irradiance levels. This paper presents a control paradigm for PV-HESS systems based on a Virtual Synchronous Generator (VSG) controller. VSG controllers aid in increasing system inertia and facilitating frequency regulation in microgrids. Simulations were run on the Matlab/Simulink platform with varied load circumstances and irradiance levels.

Keywords:

Microgrid, PV, HESS, VSG, Lack of inertia.
