Abstract
A novel energy-based control strategy to determine the switch functions of the machine-side conveter (MSC) in a doubly-fed wind generator is proposed in this paper. From the energy shaping perspective, a port-controlled hamiltonian (PCH) description for the wind energy conversion system (WECS) is obtained. Based on the description and the enegy- matching equation, the proposed switch functions enable us to realize maximum power extraction by tracking equilibrium point in the power optimization stage. This approach possesses the advantages of stable tracking performance and rapid convergence rate. Simulation results via Matlab/Simulink for 2MW WECS with a doubly fed induction generator (DFIG) confirmed its effectiveness.
