Among the different electrical energy storage technologies, Carnot batteries are promising options with low specific cost that do not suffer from geographical limitations and power-capacity coupling. In addition to power balancing, this approach can also be unique for multi-vector management. A comprehensive evaluation (thermodynamic design exergoenvironmental exergoeconomic evaluations), comparison, multi-objective optimization of four battery configurations based on solar-electric a geothermal source is presented. Geothermal simultaneously improve thermodynamic environmental performances battery. The main structure all obtained PV captured thermal source. Brayton, heat pump, flash, organic Rankine cycle (ORC) units periodically integrated. outcomes point out discharging process an ORC unit flash-heat pump (F-HPC)-based charging makes more optimal heat-to-power efficiency. Moreover, regenerative-Brayton (R-BC) has higher investment rate compared (in process). When integrating geothermal, third configuration (R-HPC/R-BC) experiences greatest improvement (5.3-fold) due increase in received

ABSTRACTPEMFC (the proton exchange membrane fuel cell) is an extremely effective energy converter system that generates electricity through electrochemical reactions. Optimizing the design of PEMFC stacks important for their proper utilization and construction. In current essay, we present a novel strategy estimating optimal model parameters cell utilizing COSA (Combined Owl Search Algorithm), improved metaheuristic algorithm. We compared performance against other published methods, comprising COA, TLBO, BH, original OSA, BBO by employing them in three different cost functions. The results show achieved minimum error values to algorithms all case studies, with 0.01, 1.20, 0.93 BCS 500W PEMFC, NedStackPS6, SR-12 500 W stack models, respectively. Our proposed approach could be utilized optimize kinds cells integrated optimization strategies improve its upcoming efficiency. Future work can focus on simplifying algorithm structure reduce complexity during process. Overall, provides tool achieving more efficient stacks.KEYWORDS: Model parametersestimationproton cellSR-12 W, 500W, NedStackPS6combined owl search AcknowledgementsThis research was supported key scientific project Hunan Province "Research Virtual Anchor Technology Based Generative Adversarial Network era intelligent Media", number: 22A0703.Disclosure statementNo potential conflict interest reported author(s).Additional informationNotes contributorsKeke YuanKeke Yuan born Hunan, China, 1982.
