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.
Fig. 3 shows a typical large scale PV plant configuration in absence of energy storage . PV panels are normally connected in series and parallel to form PV arrays. Each array can deliver a power of several hundred of kW up to few MW (direct current, DC).
Hence, the ES power rating should be, at least, 3% the maximum power the PV plant will deliver under normal conditions. Other countries such as Denmark or Mexico also specify this data (see Table 5). In terms of energy, the amount of time the PV power plant must provide under-frequency support is also commonly found in the Standards.
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.
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.
