This project aims to demonstrate and assess the reliability, resilience, and energy efficiency of a DC microgrid serving two HIMB buildings. It will compare the efficiency of powering lighting, cooling, and plug loads with AC versus DC electricity during normal operations. A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. Enhancements include development of a renewable energy generation. . With the world's transformation to low-carbon energy, island microgrids are developing rapidly because they can save energy and reduce carbon. Island multi-energy microgrids include photovoltaics, a double-fed fan, a battery energy storage system, and AC and DC loads. However, microgrids with high. . In this paper, a mixed-integer non-linear programming model is proposed for modelling island microgrid energy management considering smart loads, clean energy resources, electric vehicles and batteries.
