This paper presents an innovative approach to identify potential impacts of cyber attacks on agent-based smart grid protection relays. An agent-based protection framework is developed, where an attacker may injects a malicious breaker trip command to the relay settings. This could cause unintentional tripping of CBs, even if there is no physical disturbance on the system. It results a healthy line of smart grids to be out-of-service that leads cascading failures. An algorithm is proposed to

Using this algorithm agents can check the breaker statuses to ensure which line is out-of-service due to unintentional tripping. Furthermore, the proposed technique will be able to distinguish cyber attacks from faults on the system.
