Control and energy management of a hybrid active wing generator including energy storage system with super-capacitors and hydrogen technologies for microgrid application

A hybrid power system is studied in this thesis for the distributed generation based on renewable energy resources and energy storage systems in microgrid applications. It consists of a wind generator as primary energy source, super-capacitors as fast-dynamic storage system, fuel cells and electrolyzers as long-term storage system in hydrogen. They are all connected to a common DC bus and an inverter is used for the connection of the whole system to the grid. In this thesis, we have presented the system modeling, the control design including the power balancing and energy management strategies. This hybrid power system can finally supply controllable smooth powers as most conventional power plants. The performances have been tested in numerical simulations and also on an experimental test bench. As result, it is able to provide ancillary services to the microgrid. The main scientific contributions of this thesis are: the use and the adaptation of the graphical tools for the modeling of complex systems and their design; the design and the experimental implementation of real-time emulators in order to reduce the time and the cost of an experimental platform; the proposition and the validation of two power balancing strategies for the DC-bus voltage regulation and the grid power control and finally the proposition of energy management strategies for the active wind generator to ensure the energy availability
