Abstract: Vietnam’s economy is developing strongly, and the energy demand will increase rapidly. The development of smart grids significantly contributes to the transition to and sustainable development of energy from renewable sources, thereby improving the quality of the national power supply and promoting the economically and efficiently sustainable use of electricity. Thus, this is highly beneficial in reducing carbon emissions and other types of pollution. Additionally, the transportation industry is undergoing rapid electrification, as evidenced by the development of Electric Vehicles (EVs) and Metros in recent years. Integrating electric vehicles into the grid will enable two-way energy exchange, reactive power compensation and load balancing. However, the number of EVs participating in charging at a time will cause some conflicts, such as voltage and power loss at the nodes. Therefore, balancing the load demand and the generation source is a challenging task in planning operations. This paper presents a method to optimize island Microgrid (MG) operation with the participation of electric vehicles based on renewable energy sources. Optimisation techniques in intelligent resource forecasting and management algorithms are implemented in MATLAB to meet various requirements. The proposed Microgrid manages energy efficiency that adapts to the variability of Renewable Energy with improved efficiency.
