ENERGY FLOW MANAGEMENT STRATEGY IN AN HYBRID DC MULTISOURCE SYSTEM.

摘要

This paper will present energy flow management in order to optimize the voltage regulation of an hybrid electric system which may consist on a main renewable energy source(small windmill, photovoltaic) and lead-acid batteries energy storage system. This system is designed for small power use (few kVV) for an islanded DC network. From the point of view of the. need of a constant DC power voltage, whatever the load current fluctuation, this paper will propose to study the energy flow between the source and the energy storage source using EMR methodology (Energetic Macroscopic Representation) [1]. An experimental setup has been carried out in order to validate this approach.
