What is it about?

The hybrid renewable energy systems with DC link structure are establishing their position but the most interesting problem is the intermittent character of the principal sources ( wind velocity, temperature and solar irradiance) witch necessitates an efficient power management and energy supervisory control of the overall production system. We have analyzed the system's performance under environmental conditions and load variations.

Why is it important?

We have used tow complementary renewable sources ( solar and wind) with three time scale storage systems (long time with flywheel, medium time with battery and short time with super-capacitor ) in order to increase the stored energy. As grid connection interface, we have used multi levels inverter in order to inject the maximum of power to the grid and satisfying the load.


As a perspectives, we can note: -studying the stability of the system under grid faults. -using other type of storage systems -developing new supervisory control method.
