Multi-Agent System for Coordinated Control of FACTS Devices
Proceedings of the 15th IEEE International Conference on Intelligent System Applications to Power Systems, IEEE Press, Curitiba, Brazil, 2009-08-12


The liberalization of electricity markets and the integration of high capacity unpredictable renewable resources (e.g. wind power) yield a higher utilization of transmission networks. The capacity of transmission networks can be increased by installing Power Flow Controllers (PFCs). When several PFCs with mutual impact are installed in different control areas a distributed coordination is needed. This paper presents a novel approach for a decentralized coordination of PFCs based on multi agent systems. Serial network devices are equipped with agents which submit messages about local state information along the system topology. Controlling agents installed at each PFC analyze the received messages to gather information about the current system topology and the sensitivity for control actions on network devices. Each controlling agent evaluates this information by use of a weighting function in order to avoid wrong control actions in case of conflicting control requests. Finally this paper shows a principle simulation scenario to illustrate the operation of the proposed multi agent control.
