Abstract :
This paper concerns multisource renewable energy systems. It describes the design of an average state space model that brings a detailed physical explanation of the coupling and uncoupling of several dc/dc power converters on a dc bus. A multimodel is proposed for that purpose, which consists in a mathematical generic expression whose parameters change according to the dc/dc power converters coupled on the dc bus. This multimodel can be used as support for the design of hybrid control laws in order to optimize the energies transfers, according to the sources power variations and the load characteristics. It takes into account conduction losses in dc/dc power converters and makes it possible to evaluate the efficiency of the equipment.
