Customer ServiceHaas et al. (2022) examined the significance of electricity storage options and their economic feasibility within the context of the growing share of variable renewable technologies in electricity generation . The primary focus was on evaluating the overall welfare impact of integrating renewable sources and storage on future market design.
Integrating energy storage within power system models offers the potential to enhance operational cost-effectiveness, scheduling efficiency, environmental outcomes, and the integration of renewable energy sources.
Technologies Electricity storage can be considered as a key element in future decarbonized power systems as a result of the increasing use of renewable resources. Fuchs et al. (2012) raised awareness by revealing the functions of electricity storage systems and the strengths and weaknesses of different storage technologies .
The influence of energy storage on investment is contingent upon various factors such as the cost of storage technologies, the availability of government incentives, the design of market mechanisms, the share of generation sources, the infrastructure, economic conditions, and the existence of different flexibility options.
At the consumption level, the use of fossil fuel technologies for power generation results in more carbon emissions. Energy storage enables the seamless integration of intermittent renewable sources like solar and wind into the power grid. As a result, this fosters environmental conservation initiatives while also guaranteeing stable power quality.
Through simulation, it was found that the cost-effectiveness of energy storage depends remarkably on both the round-trip efficiency and power-to-energy ratio of the battery storage, highlighting their importance. A comprehensive evaluation and design of ESS software tools were conducted by Nguyen and Byrne (2021) .
