Overcurrent Relay for Generation Distribution Utilization [PDF]
ELEKTRIKA- Journal of Electrical Engineering, 2022 Distributed Generation (DG) is the production of electricity from a variety of renewable energy sources that is closer to the customer and load. The addition of distributed generation sources to the distribution networks alters the characteristics of distribution system and has an influence on its protection coordination.
