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.
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.
Then, 3 winding transformers are in charge to step up the LV to a medium voltage (MV) level and to deliver the generated power to the PV plant collection grid. This internal grid collects and transmits the generated power to the external grid, where a power transformer steps up the MV to high voltage (HV) level.
The reliability and efficiency enhancement of energy storage (ES) technologies, together with their cost are leading to their increasing participation in the electrical power system .
The active power requirement can reach levels up to 10% of the PV power plant nameplate capacity. This means MW-scale during 30 min. In contrast, the response time is relatively slow (15–30 s). In this case, Li-Ion is the ideal ES technology. Its power, energy and response time capacities comply with the requirements.
