摘要:The emergence of renewable energy with high consumers' energy demand has led to the concept of micro-grids in the world in recent years. The development and expansion of micro-girds with renewable energy is facing challenges with the protection needing serious attention. The challenges result from the difficulties in coordinating protection devices. The presence of various energy sources makes the micro-grid protection sensitive to changes in current and voltage levels. A micro-grid operates in parallel or independently with the existing utility network as grid-connected mode or islanded mode, respectively. Whatever the mode of operation, the protection system has to detect short circuits and clear faults to isolate only the faulty portions. In this study, micro-grid protection comprehensive review is performed to discuss the present situation. Protection issues and existing protection schemes for micro-grid are presented based on the previous achievement in the area. This work will contribute in the assessment and implementation of micro-grid protection to provide reliable and safe electricity to consumers.
