Different energy storage systems have been studied and developed over the last two decades. Most of the systems introduced were the electrical, chemical, electrochemical, thermal, and mechanical energy storage 9, 10, 11.
According to Heindl 21, the efficiency of the round-trip gravitational energy storage system can reach more than 80%. Gravity storage systems were studied from various perspectives, including design, capacity, and performance. Berrada et al. 22, 23 developed a nonlinear optimization model for cylinder height using a cost objective function.
However, these systems are highly affected by their design parameters. This paper presents a novel investigation of different design features of gravity energy storage systems. A theoretical model was developed using MATLAB SIMULINK to simulate the performance of the gravitational energy storage system while changing its design parameters.
When there is a need to recover the stored energy, the piston is allowed to descend by opening a valve, allowing water to flow through a hydraulic turbine and generate electricity. According to Heindl 21, the efficiency of the round-trip gravitational energy storage system can reach more than 80%.
Electrochemical energy storage modes, represented by batteries, can tolerate high peak fluctuations, whereas physical energy storage modes, represented by CAES, have lower response frequencies. As a result, the Fe battery only requires relatively soft power, resulting in a small peak power.
