Abstract: Integration of an energy storage system (ESS) into a large-scale grid-connected photovoltaic (PV) power plant is highly desirable to improve performance of the system and overcome the stochastic nature of PV power generation.
When the day lighting conditions are fixed, the three relationships are directly related to the magnitude of Photovoltaic penetration. Obviously, ESS cannot store energy in condition (1). The PV energy storage system cannot (or just happens) to supply all peak load requirements. When it is in condition (2).
ESS is used as a tool to stabilize the fluctuation of photovoltaic output, and the charge and discharge control strategy of the energy storage system is designed based on the Nordic power quality standards in (Schnabel and Valkealahti, 2016).
Energy storage at a photovoltaic plant works by converting and storing excess electricity generated by the photovoltaic plant, and then releasing it when demand increases or production is reduced.
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.
This aligns with California's WAIRE Program, which incentivizes warehouses to adopt solar energy to reduce emissions and earn compliance points. Solar energy helps warehouses slash their electricity bills by generating clean power onsite. Many facilities report savings of 20–40% on their energy costs.
Energy storage requirements in photovoltaic power plants are reviewed. Li-ion and flywheel technologies are suitable for fulfilling the current grid codes. Supercapacitors will be preferred for providing future services. Li-ion and flow batteries can also provide market oriented services.
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 .
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.
