The Integration of Photovoltaics and Energy Storage: A Game
Photovoltaics (PV) refers to the technology that converts sunlight directly into electricity using solar panels. Energy storage systems, on the other hand, store excess energy
PV technology integrated with energy storage is necessary to store excess PV power generated for later use when required. Energy storage can help power networks withstand peaks in demand allowing transmission and distribution grids to operate efficiently.
Knowing this amount of time and the required storage power, the energy storage capability can be easily obtained (P t). To sum up, from PV power plants under-frequency regulation viewpoint, the energy storage should require between 1.5% to 10% of the rated power of the PV plant.
Assuming the power from the PV system is entirely consumed by the building's electricity demand without considering the energy loss, the PV system can theoretically account for 33.9 % of the building's annual electricity demand.
As a solution, the integration of energy storage within large scale PV power plants can help to comply with these challenging grid code requirements 1. Accordingly, ES technologies can be expected to be essential for the interconnection of new large scale PV power plants.
