Abstract

This paper deals with the modeling and control of a hybrid production unit based on renewable energies comprising two sources: wind/solar and hydrogen storage system. These subsystems have different voltage-current characteristics and consequently are integrated with static converters on a DC bus by using a suitable control system.  This DC bus is coupled to a load or grid through a static inverter.  Each production source is provided by a regulator ensuring the Maximum Power Point Tracking (MPPT). The control strategy of the studied Hybrid Renewable Energy Source (HRES) is decomposed into two parts: a local control depending on the power structure and a global control deduced from global considerations. This strategy leads to achieve power objectives (active and reactive power targets) and system constraints.
