A hydropower station with a control reservoir can be likened to a battery for the electrical system; storing water is storing energy. If requested by the system, it is possible to increase generation within minutes.
Adding battery capacity to the system facilitates better matching of the generation and price of hydropower plants. The increase in generation in hydropower plants with increasing installed power storage may be the reason for the increase in profits to some extent. The increased storage capacity also allows for a greater generation of hydropower.
In terms of profit and hydropower planning, a medium-proportion battery was found to be the most suitable. Increased variability in hydropower generation results from the installation of an energy storage system. 1. Introduction
