BESS Techno-economic challenges to support wind energy: Mind mapping and correlation matrix

This paper proposes a compact approach to perform a preliminary techno-economic feasibility study to decide the technology and size of Battery Energy Storage System (BESS) that is suitable to particular application(s). A detailed mind matrix is proposed to provide a high-level vision of the incorporated technoeconomic challenges and questions within the process, where 38 issues are expansively considered. Afterwards, a prioritization scheme is presented to evaluate the benefits and required capacity of BESS integration aiming to mitigate the complexity of such study. A simplified costing model is also discussed to highlight the main factors that judge the financial value of the BESS. This paper provides spotlight on the key knowledge gaps and research areas that could be of interest to industry and academic stakeholders.
