Abstract

© 2017 IEEE. Modern power system is more flexible and complex than the conventional power system. From a reliability point of view it is important to identify and isolate the fault as fast as possible from the neighbouring zones. This paper proposes protection solutions for smart grid. In particular, the main focus of this paper is on three different protections namely overcurrent protection, transformer protection, and directional overcurrent protection. The proposed protection solutions are validated through IEEE- 9 bus and 14 bus electrical power systems. ETAP software has been used to verify the system operation.
