Cover Story: Recently, hybrid multi-energy systems have been receiving great attention as a promising option to meet the multi-energy demand of residential end-users. The design problem of such systems is challenging due to the large number of degrees of freedom in the design and operation phases, so the system as a whole must be optimized. The study presents a methodology for optimal design from the economic and energetic perspectives of multi-energy nano-grids operating in grid-connected and islanded modes. View this paper.
