Abstract:

The present situation in the power system network is to realize more number of distributed energy sources. These increased distributed generators in the distribution network are causing specialized issues such as power quality, power energy balance, and protection, etc. However, the protection of micro-grid is most important. Local generation in a combination with a possible islanded activity can pose protection sensitivity and selectivity issues in case of fault clearing depend upon the relay settings. This paper focuses on novel adaptive microgrid protection systems using Numerical relay and advanced communication. The protection system is based on a centralized architecture where relay protection settings are modified centrally concerning a micro-grid operating condition.
