PROTECTION ISSUES IN MICRO GRID

Microgrid is cluster of distributed generation sources, storage systems and controllable loads. Microgrid can provide quality and reliable supply of energy to consumer. Microgrid can operate in both modes of operations that is grid connected mode and islanded mode. This implementation poses technical challenge of protecting the micro grid. Power quality, energy management, stability, power flow control, protection system and integration of various distributed generators are the major issues in the microgrid operation. This paper reviews various protection issues in micro grid, various protection schemes to overcome the protection issues are also discussed. Implementation of adaptive protection system using digital relaying and advanced communication is most successful method of the protection of micro gri
