Implementation of an electrical energy storage system in an existing small hydropower plant

The subject of this paper is the implementation of battery energy storage system (BESS) to the automated control of a small hydropower plant (SHPP). The system is based on the principle of evacuation of electrical energy to storage modules and vice versa, under certain conditions. The principle of an automated system is to automatically transfer the generated and stored energy to the grid at specified times, and store it in the redundant system at other times. The system is used both for commercial storage and for balancing a group of small power plants as needed.
