ABSTRACT: Electrical energy plays a significant role in society since it maintains a high standard of living and stable economic development. Electric energy consumption has been gradually increasing in recent history, and this need is expected to increase more in the future. The majority of power today is generated by the combustion of fossil fuels, and there are considerable worries about the associated emissions. Renewable energy sources emerged as a feasible substitute for ecologically damaging ones. However, renewable energy sources have significantly unpredictable environmental circumstances when it comes to power generation and cannot be immediately integrated into the existing electrical system. The increased usage of renewable energy systems in recent years has increased the necessity of establishing microgrids. Energy is used where it is produced in microgrids. As a result, transmission and line losses are reduced to zero. At the same time, the micro grid model eliminates the negative impacts of commercial plants that disturb electricity standards, and more efficient and dependable grids are frequently built. A micro-grid is a grouping of micro-sources with a load and an optional energy device inside a certain area. The microgrid is normally operated in one of three modes: autonomous, non-autonomous, or dual. A micro-grid should generate and control its own energy in an independent operation. In this study, control applications on microgrids and the hierarchical control approach applied for microgrid architectures are investigated from a literature review. The pros and cons of these control methods are compared with one another. The key feature is to retain the frequency and voltage values of an islanded micro grid system within acceptable limits. Clean and green energy will be provided to the consumers of Büyükada (project’s site). The island will be self-sufficient for its energy needs.
