Design of a tidal turbine conversion chain with no mechanical sensor
This thesis subject concerns the design of a tidal energy conversion chain where the aim is to remove the mechanical sensors (sensor of the water current and turbine rotation speed) by taking full advantage of our theoretical knowledge on electrical machinery and marine energy.
With that in mind, we will be developing digital tools (software sensors) to estimate the speed of rotation of the turbine shaft and of the water current, by using the mathematical model of the generator as well as marine current probabilistic or statistical models. An MPPT algorithm will then be implemented to analyse these estimates and check how accurate they are.
During this thesis, we will also consider the injection of electrical energy into the network by proposing appropriate control algorithms aimed at maintaining the stability of the electrical network and minimising the harmonic rate injected.

Then, in 2018, he was awarded an engineering degree in Electrical Engineering, Embedded Systems and Numerical Control by the Khouribga National School of Applied Sciences. The same year, he enrolled in Casablanca’s National Graduate School for Electricity and Mechanical Engineering (ENSEM) at Hassan II University as a PhD student at the Engineering Research Laboratory (LRI), in the System Architecture Team (EAS), in partnership with FRDISI-EIGSI. His research explores control systems engineering and technologies associated with renewable energy sources.
