Another theoretical mechanical stored energy concept is called the gravity power storage system. Unlike the hydraulic rock storage system described in Abschn. 9.3.2.1, the dimensions of the gravity power system are small. The storage principle is also slightly different, since it uses the same principle as the power tower system (Abschn. 9.3.2.3 ).
Mechanical storage systems work on the basis of storing available and off-peak excessive electricity in the form of mechanical energy. Once the demand for electricity power overcome the available energy supply, the stored energy would be release to meet with the energy demand.
Operating principle of a gravity power type mechanical energy storage facility during charging and discharging [ 123] A flexible seal is required to build up pressure without allowing the water to mix. Since the piston moves very slowly, friction at the seal is assumed to be negligible.
Hence, mechanical energy storage systems can be deployed as a solution to this problem by ensuring that electrical energy is stored during times of high generation and supplied in time of high demand. This work presents a thorough study of mechanical energy storage systems.
Mechanical energy storage systems are very efficient in overcoming the intermittent aspect of renewable sources. Flywheel, pumped hydro and compressed air are investigated as mechanical energy storage. Parameters that affect the coupling of mechanical storage systems with solar and wind energies are studied.
The most commonly used systems to store mechanical energy are pumped hydroelectric storage and flywheels [14, 15], while some of the other systems are that of hydraulic accumulators, compressed air, springs, and gravitational potential.
