In this study, a HESS combin-ing gravity energy storage (GES) with high-power electrochemical energy storage is integrated into a hybrid energy system (PV/WIND) to balance supply and demand in a renewable energy power system. In a common application, when renewable energy sources such as wind and solar provide more energy than is immediately. . Advanced energy storage systems (ESS) are critical for mitigating these challenges, with gravity energy storage systems (GESS) emerging as a promising solution due to their scalability, economic viability, and environmental benefits. This paper proposes a multi-objective economic capacity. . Dear Reader, Renewable energy from wind and solar sources is now making a rapidly increasing contribution to global power supplies, with a growth rate of over 20% per year.
