Underwater pressure storage system for wind and solar power plants (Case study: Caspian sea)

Energy storage is one of the essential technologies alongside renewable energy sources. Renewable energy sources such as wind and solar energy require energy storage systems due to their inherent uncertainty and dependence on environmental conditions. In this paper, an energy storage system based on underwater pressure is investigated. The implementation of this system is examined on the southern coast of the Caspian Sea. This simulation is carried out using MATLAB software. Two renewable energy power plants are designed and simulated. For the simulation of the power plants, a wind power plant is simulated using HOMER software. A solar power plant simulation is performed using PVsyst software. The results show that this energy storage method, considering the geographical conditions of the region, can meet the energy storage needs of the two power plants under consideration.
