Abstract

This paper analyses the possibility of forming an isolated microgrid using a Wind Energy Conversion System (WECS) to supply the loads and control the microgrid voltage and frequency. The proposed scheme uses a diode rectifier and a Voltage Sourced Converter (VSC) to control the WECS instead of the most common back-to-back structure with two VSCs. Wind turbine pitch control is used in a novel way in order to ensure active power balance. To validate the presented algorithms, experimental results from a low power test-rig, which includes a wind turbine emulation system, have been obtained.
