Abstract: This paper proposes an innovative based on a multi-agent system to increase the stability and security of power systems. For increasing the safety and reliability of protection for distribution networks, a multi-agent system (MAS) is proposed for fault location, fault line isolation, distance estimation, and automatic power restoration. The multi-agent system proposed consisting of several smart agents to provide real-time data and power flow between different physical processes of electrical networks, allowing various switching arrangements of the circuit breakers (CBs) control in the electrical systems. The detection, location, and analysis of fault required intelligent devices and techniques to protect the systems from failure and blackouts. The performance of the proposed algorithm based on a combination of two algorithms is tested on a part of Kenitra city distribution system in Morocco under several large changes and challenges such as voltage drop, short-circuits faults, and circuit breakers fail in the systems. The results of simulation show that the proposed approach based on multi-agent system combined with impedance fault method for fault location significantly improves the stability of power systems.
