Contribution au pilotage des sources hybrides d'énergie électrique

Abstract : This thesis deals with the control of electrical hybrid system. The main sources consist in an association of photovoltaic and fuel cell system. The secondary sources are a bank of batteries and a bank of supercapacitors. The sizing of secondary sources is realized to manage the power during the transient state and provide extra energy when the power of main sources is insufficient in steady state. The main sources provide the essential energy of the electrical hybrid system during steady state. The control of energy flows and power tracking used in this thesis are based on the flatness technique. This control system allows obtaining high dynamic properties in the power tracking and the regulation of system. The supervisor for sharing the power between the different storage devices is realized thanks to a fuzzy logic controller. This controller ensures that the bank of supercapacitors with its interface converter is used as a power filter and provides the energy in transient states. However, the bank of batteries provides or absorbs the energy in longer periods especially during recovery or overload modes
