They open up new paths to a carbon-free, dependable, and resilient electric system. DC Microgrids are becoming more prevalent as power electronic converter technology advances. Today and in the future, higher fuel prices, deregulation, and environmental constraints present more opportunities for the use of renewable energy sources (RES) in power systems. A micro grid idea is necessary to integrate renewable energy sources into the electrical system. As a result, this proposed system has a micro grid control mechanism involving solar (PV), battery energy storage systems (BESS)and wind. To begin, voltage control alternatives for an island micro grid are investigated using hierarchical control approaches. Furthermore, the cost and electricity generated by renewable sources are calculated. Finally, this study presents an energy management system for micro grid functioning. In grid-connected mode, MATLAB and Arduino programming are used to find the lowest cost of electricity generation and power availability. The simulation results indicate that the suggested solutions are close to being accurate and efficient. The corresponding hardware model has been implemented. Index Terms— first environmental constraints, energy management, cost effective. I. INTRODUCTION Because of the growing concern about sustainability and energy consumption, governments, academics, and investors are becoming more interested in renewable generating, resulting in an increase in the number of renewable power systems integrated into present electrical grids. Renewable energy penetration, on the other hand, is hampered by its variability and intermittency, prompting the development of Microgrids powered by renewable power sources. These decentralised power systems, whether grid-connected or islanded, are thought to be the most viable approach for boosting clean energy penetration in the future, and have gained increasing relevance in recent years because to their widespread availability and low production costs. As the use of solar power expands, so does the need to improve the quality of the energy produced. Renewable energy technologies are becoming increasingly the most cost-effective way to build new capacity in an increasingly diverse world and areas, and they are typically the most cost-effective way to build when there is new grid-connected capacity and sufficient resources available. Costs have been driven down by the rapid adoption of renewable energy generation technology and strong learning rates. Renewables are predicted to become extremely competitive with fossil fuels in countries across the world as a result of this trend, and the most cost-effective option in a growing number of markets. Renewables contributed for 72 percent of new capacity additions globally in 2019 indicating their productivity and competitiveness. Renewable energy's cost competitiveness has hit new heights, with 56 percent of new utility-scale capacity costing less than the cheapest new coal option.
