Título del libro: Proceedings Of The Xxii 2020 Ieee International Autumn Meeting On Power, Electronics And Computing (ropec 2020), Vol 4 Título del capítulo: Off-grid Wind Energy Conversion Systems based on Multilevel Cascaded H-bridge Topology in Real Time Simulation
In this paper, the modeling and real time simulation of an off-grid wind
energy conversion systems based on isolated multilevel cascaded H-bridge
topology is presented. The system is tested under a synthetic wind speed
signal generated by Gaussian Process, even with wind variations. The
off-grid WECS structure is made through an AC/DC power converter formed
by a VSC in rectifier mode, which is designed through the permanent
magnet synchronous generator characteristics; the DC voltage is isolated
by a DC/DC modified boost converter and subsequently is applied to the
DC/AC multilevel cascaded H-bridge of 5-levels converter. The system
validation is achieved in MATLAB-Simulink (R) and with the laboratory
tests using the concept of model in the loop and the real-time simulator
Opal-RT Technologies (R). The obtained results show a robust and
effective methodology generating a total output power of 30 kW off-grid.
