PV plant intermittency mitigation using constant DC voltage PV and EV battery storage

The increasing presence of photovoltaic(PV) renewable power generation and plug-in hybrid electric vehicles (PHEV) in national infrastructure leaves utilities, PV-inverter and battery charger manufacturers searching for means to mitigate destabilizing effects of renewable intermittency and battery charging loads on traditional utility grids. Small amounts of battery storage can be interfaced to the PV-inverter system´s dc-link to effectively reduce the fast transient changes in PV output power, enabling a greater presence of grid-interactive PV generation and providing means of alleviating the grid from growing demands of battery charging loads.
