Tiivistelmä
After microgrid transition from the normal operation to the islanded operation the system impedance changes considerably and it affects on the harmonic voltages of the microgrid. In this paper the voltage and current THD before and after islanding are studied with different microgrid configurations. Simulations are also made by applying negative sequence filtering in control system of converters to reduce the voltage and current THD inmicrogrid during unsymmetrical load. Based on the studies recommendations for technical solutions which ensure high power quality in islanded microgrid are given.
