A microgrid is a small-scale power system unit comprising of distributed generations (DGs) (like photovoltaic (PV), wind turbine (WT), fuel cell (FC), micro gas turbine (MGT), and diesel generator), energy storage (like batteries), and loads piled in close proximity to each other.
Multi-objective energy management in a microgrid incorporating PEVs entails the optimization of multiple competing objectives, including minimizing energy expenses, mitigating greenhouse gas emissions, and guaranteeing a dependable and resilient power provision 29, 30, 31.
Microgrids of renewable energy sources (RES) and energy storage (ES) units synchronize their power generation with changing load needs while considering each microgrid’s available power after meeting its local demand. Microgrids may prioritize stored energy and optimize RES generation during low-demand times.
