Solar Organic Rankine Cycle (ORC)-based power generation plants leverage solar irradiation to produce thermal energy, offering a highly compatible renewable technology due to the alignment between solar irradiation temperatures and ORC operating requirements. Their superior performance compared to steam Rankine cycles in small-scale applications makes them particularly relevant within the smart grid and microgrid contexts. This study explores the role of ORC in peer-to-peer (P2P) energy trading ...
