Novel Backup Protection System for the Electric Power Grid Using Agent

This paper proposes a novel backup protection system for the electric power grid that makes use of Agents. Faster and allowing for more selective protection, the new relays are significantly better than their traditional counterparts. Maloperation is reduced by the Agent's self-checking and self-correcting ability. This paper presents the basic conception of Agents and analyzes the communication networks for relay Agents. The principle structure, protection strategies and IP-based communication methods of the Agent-based backup protection are proposed. Simulations run in a typical power system using the EPOCHS platform illustrate the effectiveness of the proposed method.
