The renewable energy sources are, and will be more and more, brought to cohabit on the same site. However, they have not yet the subject of a real overall energy management strategy. As several systems rely on multiple energy sources, power distribution strategy must be implemented by matching the supply and the demand. The balance between production and consumption must be carefully conducted to ensure the availability of power. This paper addresses decentralized control strategies of multi-sources and multi-users energy systems. The objective is to describe, by using the recursion principle of the holonic paradigm, a decentralized multi-sources, multi-users energy system. The bases of multicriteria decision aid method are presented to ensure, in an adequate and automated way, the several possible switchings between the various energy sources of the system.
