We have been constructing circuits in MATLAB Simulink and testing different Maximum Power Point Tracking (MPPT) methods. Pictures below show the circuit of a PV-array with different MPPT control strategy and the readout from the simulation.

We have performed some exercises in the renewable energy laboratory to get familiar how different energy systems perform in the power grid. This picture shows the DFIG setup. It is a doubly-fed induction generator. This is one of the most used generators in todays wind turbines.
