The use of energy storage systems (ESS) in PV power plants allow an optimal performance in all PV systems applications. For power plants oriented to the self-consumption, ESS allows minimize the exchange with the grid, increasing the percentage of energy used from photovoltaic generation.
Li-ion and flow batteries can also provide market oriented services. The best location of the storage should be considered and depends on the service. Energy storage can play an essential role in large scale photovoltaic power plants for complying with the current and future standards (grid codes) or for providing market oriented services.
Nonetheless, it was also estimated that in 2020 these services could be economically feasible for PV power plants. In contrast, in , the energy storage value of each of these services (firming and time-shift) were studied for a 2.5 MW PV power plant with 4 MW and 3.4 MWh energy storage. In this case, the PV plant is part of a microgrid.
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.
In addition, considering its medium cyclability requirement, the most recomended technologies would be the ones based on flow and Lithium-Ion batteries. The way to interconnect energy storage within the large scale photovoltaic power plant is an important feature that can affect the price of the overall system.
In the review , the focus is put on the intermittence issue of roof-top PV power plants and the use of energy storage systems for avoiding reverse power flows. In , a study of a hybrid PV storage power plant for power dispatching is performed.
