FACTS (Flexible AC Transmission Systems) and in particular SVC (Static Var Compensator) and STATCOM are devices suitable for voltage stability and power quality improvement in grids. They offer remedies to voltage drops and fluctuations, harmonic distortion, and unbalance between phases, caused for instance by wind generation, heavy industrial processes or high speed rail traffic. The paper gives...
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...
