What is the function of Energy storage converter?
The energy storage converter performs several important functions, including:
Converting DC to AC power: Many energy storage systems store energy in the form of DC power, which is not compatible with the AC power used by the electrical grid. The energy storage converter converts DC power to AC power, allowing it to be fed back into the grid.
Maintaining grid stability: The energy storage converter is designed to regulate the flow of energy between the energy storage system and the grid, ensuring that the system does not overload the grid or disrupt its stability.
Balancing power supply and demand: The energy storage converter can also be used to help balance power supply and demand on the grid, by feeding excess energy back into the grid during times of high demand and storing energy during times of low demand.
Monitoring system performance: The energy storage converter provides information on the performance of the energy storage system, including energy usage, battery status, and other important metrics.
