Application Scenarios of Energy Storage in Power Systems


By integrating photovoltaic energy storage systems, it is possible to achieve complete self - generation and self - consumption of electricity.
 
Without an energy storage system, the electricity demand at night still has to be met by purchasing power from the grid.
By integrating an energy storage system with the photovoltaic (PV) system, households can ensure that their electricity needs, both during the day and at night, are met by their own PV generation, thus saving on electricity bills.
 
Residential energy storage can effectively deal with power outages and improve the quality of electricity consumption for residents.

Residential energy storage systems are generally defined as systems with a load power of ≤ 20kW and an energy storage capacity of ≤ 40kWh. These systems utilize lithium - ion battery technology and energy sources such as photovoltaics. Through an inverter, the electricity generated by the photovoltaic system is stored in the battery, and the energy stored in the battery is released when needed.
For example: the energy storage system stores solar energy in the battery during the day for use on days with poor weather or when there is a power grid failure. After the battery is fully charged, the excess solar energy is used to power the load. In some areas, this excess energy can be automatically sold to the grid. When there is insufficient power, electricity can also be automatically purchased from the grid
