[PDF Version]Battery Energy Storage Systems (BESS): PCS is essential in large-scale battery energy storage systems where it converts the stored DC power into AC for grid use. These systems help balance intermittent energy generation from solar and wind with demand on the grid. Renewable Energy Integration: PCS is also used in solar and wind power systems.
When there is a great shortage of electricity supply on the generation side, the energy storage devices act as a power source, converting the stored energy into electrical energy to be fed back into the power system.
Between the DC batteries and the electrical grid, the PCS serves as an interface. How does a PCS work? To achieve the bidirectional conversion of electric energy, a power conversion system is a component connected between the energy storage battery system and the power grid.
Therefore the ESS capacity can be allocated reasonably to restrain the power fluctuation of the PV station and improve the stability of the power system. Hence, The ESS is optimized used. Figure 16.13. Grid-connected control strategy of energy storage system based on additional frequency control.

There are a few reasons why it makes sense to buy an energy storage system to complement your PV system: With a PV storage system, you can use your electricity generated by the photovoltaic more effectively. For example, surplus electricity produced during the day can be stored and used in the evening when less solar energy is available.
Slotting energy storage into an existing system can also reduce the need to build additional generation assets if existing transmission or distribution assets might be hard-pressed to meet increases or changes in demand.
Energy storage assets can augment any number of resources in an electricity system, including complementing the intermittent generation of renewable assets, responding to fluctuations in grid demand, helping meet peak demand, or reducing the need for generators to increase their output.
Energy storage can also serve as a backup if power generation is interrupted, boosting the reliability and resilience of the system, and helping to reduce the negative environmental impacts of increased energy demand through the support of renewables, a reduced need for generation, and avoiding peaking.
A PV energy storage system is a battery that is charged as soon as the production of PV electricity is higher than the consumption. More precisely, this means that the solar radiation hits the photovoltaic system, which generates direct current.
A photovoltaic energy storage system is always worthwhile if you produce more electricity with your PV system during the day than you consume, as this allows you to increase your own consumption.
