چکیده
In this paper the authors have developed an isolated network for very low voltage (VLV) decentralized energy production and storage based on renewable energy (hybrid system: photovoltaic and wind). An energy based model of stand-alone hybrid photovoltaic-wind generating system is presented, using bond graph approach. An equivalent average modeling of a hybrid photovoltaic-wind generating system is used. The modeling of the components of the global system is developed with the integration of converters losses involved in the solar and wind generating subsystems. It is shown that this model is interesting for analyzing the dynamic behavior of the system and for designing the control strategy. The energy management and control of the photovoltaic and wind subsystems are based on voltage and current control with Maximum Power Point Tracking (MPPT) allowing the optimal transfer of power to DC load.
