Power and Energy Rating Considerations in Integration of Flow Battery with Solar PV and Residential Load

Integration of renewable energy sources such as solar photovoltaic (PV) generation with variable power demand systems like residential electricity consumption requires the use a high efficiency electrical system battery. In present study, integration has been studied using vanadium redox flow battery (VRFB) storage specific focus on sizing and capacities components. Experiments have carried out seven-day simulated insolation load characteristics 1 kW VRFB stack amounts electrolyte volume. Several scenarios scale factors. Battery response, in terms its power, state charge efficiency, monitored each run. Results show that rating should be based peak charging while volume expected daily discharge through The PV source itself sized at about 25% more than average load. ability to design power-to-energy ratio makes it particularly attractive for PV-load integration.
