New Trends in Micro and Hybrid Energy Grids

Micro-grids improve the security of supply within the micro-grid cell, and can supply emergency power, changing between island and connected modes. They also offer an option for rural electrification in remote areas and on smaller geographical islands. As a controllable entity, a micro-grid can effectively integrate various sources of distributed generation (DG), especially Renewable Energy Sources (RES).Hybrid renewable energy systems are becoming popular as stand-alone power systems for providing electricity in remote areas due to advances in renewable energy technologies and subsequent rise in prices of petroleum products. A hybrid energy system, or hybrid power, usually consists of two or more renewable energy sources used together to provide increased system efficiency as well as greater balance in energy supply.
