Multi-agent based Autonomous Power Distribution Network Restoration by using Contract Net Protocol

Abstract

A nobel multi-agent-based system with the contract net protocol (CNP) for achieving distributed approach for power distribution network restoration is proposed. Agents in the proposed system are assigned to each area sectioned by switches, and exchange environmental information among them at all times. The information is used for constructing a overlay network of the CNP against network accidents. Parameters of CNP required for the robustness and effectiveness are optimized by the genetic algorithm (GA) in the operation phase. When a network accident occurs, the agents restore the power distribution service autonomously through the overlay network constructed by CNP. Simulation experiments indicate that the CNP allows the power distribution network to make effective strategy of the restoration by each agent cooperating.
