In recent years, the voltage rise at the end of distribution line and the increase of harmonic voltages has become to be greatly concerned because of extreme expansion of distributed generation (DG) systems and excessive amount of static capacitors (SCs) for improving power factor. For compensating leading current and harmonic currents from consumers, the hybrid type of power quality conditioner was...
Since a superconducting magnetic energy storage (SMES) unit with a self-commutated converter is capable of controlling both the active and reactive power simultaneously and quickly, increasing attention has been focused recently on power system stabilization by SMES control. In this study, a fuzzy gain scheduled supplementary control scheme with SMES unit is proposed and applied to automatic generation...
With the increase in size and capacity of electric power systems and the growth of widespread interconnections, the problem of power oscillations due to the reduced system damping has become increasingly serious. Since a superconducting magnetic energy storage (SMES) unit with a self-commutated converter is capable of controlling both the active and reactive powers simultaneously and quickly, increasing...
Static synchronous compensator (STATCOM) using self-commutated converter is one of the most effective flexible AC transmission systems (FACTS) devices for voltage control, power factor correction, and power system stability enhancement. However, to achieve such functionality, a proper and sufficient control system should be designed for this device. This paper proposes a new control scheme for STATCOM...
The anticipated growing penetration of inverter-interfaced DER affects several aspects of power system analysis ranging from the impact on the system behavior to the modeling and simulation needs of the new technologies. The adequate representation and assessment of the role of the self-commutated converters is addressed through a number of challenges illustrated by a set of examples dealing with...
