1. Introduction. Increasing demand for energy and concerns about climate change stimulate the growth in renewable energy [1].According to the IRENA''s statistics [2], the world''s total installed capacity of renewable energy increased from 1,223,533 MW in 2010 to 2,532,866 MW in 2019, and over 80% of the world''s electricity could be supplied
Energy storage systems (ESSs) are recognized as one of the promising methods to address this challenge. For multi‐area power system planning problems, capacity allocations of RESs can vary considerably among areas accounting for the geographic diversities in RES generation and load patterns.

Reasonable optimization of the wind-photovoltaic-storage capacity ratio is the basis for efficiently utilizing new energy in the large-scale regional power grid.
Higher storage pressures generally require more energy for compression, potentially leading to increased greenhouse gas emissions if the energy source used for compression is carbon intensive. Despite fuel cells and electrolysers require the use of critical and transient metals, such as platinum and titanium, as well as rare-earth metals
Lithium-ion batteries are the most widely used type of batteries in energy storage systems due to their decreasing cost over the years. As of 2024, the average cost for lithium-ion batteries has dropped significantly to R2,500 per kilowatt-hour (kWh), making energy storage systems more financially viable and accessible for businesses.
