In the context of solar power plants, thermal energy storage (TES) systems have drawn a lot of interest as a means of reducing the intermittent nature of solar energy and enhancing overall system efficiency. Through a thorough investigation, this paper seeks to determine the efficiency of TES systems in solar power plants.The paper starts out by discussing numerous TES innovations, such as sensible heat storage, latent heat storage, and thermochemical storage, that are frequently used in solar power plants. Examining each technology's advantages and disadvantages while taking into account elements like thermal efficiency, cost, and system integration.The research then investigates how TES systems affect solar power plant performance. It looks at how TES devices can improve solar energy utilisation by storing extra thermal energy produced during high solar radiation times and delivering it during low or no solar radiation periods. It is evaluated how the impact will affect grid integration, power output stability, and overall system efficiency.Additionally, it is assessed whether installing TES systems in solar power plants will be financially viable. Cost factors are examined, including capital expenditures, ongoing maintenance costs, and possible revenue from increased system performance. The potential for TES systems to support grid stability and energy market participation is also covered in the report.The usefulness of thermal energy storage devices in solar power plants is thoroughly examined in this research. The findings show that TES systems have the potential to overcome the intermittent nature of solar energy and boost the general effectiveness and financial feasibility of solar power generation. The results open the way for the broad use of TES systems in solar power plants and contribute to continuing research and development efforts in the area of renewable energy integration.
