1. Introduction. In recent years, the global power systems are extremely dependent on the supply of fossil energy. However, the consumption of fossil fuels contributes to the emission of greenhouse gases in the environment ultimately leading to an energy crisis and global warming [1], [2], [3], [4].Renewable energy sources such as
They can be classified into two main types: photovoltaic (PV) power plants and concentrated solar power (CSP) plants. Photovoltaic power plants convert sunlight directly into electricity using solar cells, while concentrated solar power plants use mirrors or lenses to concentrate sunlight and heat a fluid that drives a turbine or engine.
The intermittency of renewable energy sources makes the system unable to meet the load demand without possible loss of supply. Therefore, gravity energy storage system is integrated to the power plant to improve the system reliability by storing the surplus energy and delivering it back during peak demand periods.
Hydrogen energy storage is positioned in renewable energy systems differently from electrochemical energy storage, with a predominantly long-period, inter

Pumped-storage power plants are reversible hydroelectric facilities where water is pumped uphill into a reservoir. The force of the water flowing back down the hill is then harnessed to produce electricity in the same way as conventional hydroelectric plants. Their ability to store electricity makes them an effective tool to overcome the
Pumped Storage Power Plant Pumped Storage Power Plants are a special type of power- plants, which work as conventional hydropower stations for part of the time. In a hydroelectric power station water is stored behind a dam in a reservoir. This water has gravitational potential energy. the water runs down through pipes to turn the
Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location.
