Are energy storage services economically feasible for PV power plants?

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.

Which technology should be used in a large scale photovoltaic power 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.

How much energy does a PV plant need?

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 terms of energy, it is required, at least, to provide full power during 9–30 min (see Table 5).

What support devices can be used in a large scale PV power plant?

In addition, there can be other supporting devices such as FACTS, capacitor banks or storage systems to provide grid support functions. As shown, large scale PV power plants have several generation units (generation unit = PV array + converter).
