A Multi-Agent Fuzzy Logic Based Energy Management of Hybrid Systems

Abstract

Hybrid energy systems (HES) for renewable energy sources are an interesting solution to power stand-alone systems. However, the energy management of such systems is quite complex when it relies on a central controller. With a central controller, the energy management system (EMS) has to be redesigned when the configuration is changed (for example with the addition of a new device). This paper proposes a distributed EMS to control the energy flow in the HES. This distributed controller is based on multi-agent system (MAS) technology. With this concept, a HES is seen as a collection of different elements that collaborate to reach a global coordination. The agent-approach for HES is explained and a MAS is presented. Finally, a simulation model of the HES controlled by a MAS is proposed and the system reaction is detailed.
