Abstract: The STATCOM (synchronous static compensator) based on voltage source converter (VSC) is used for voltage regulation in transmission and distribution systems. However, strict requirements of STATCOM losses and total system loss penalty preclude the use of high frequency PWM (pulse-width modulation) for VSC based STATCOM applications. This constraint of implementing VSC without PWM results in VSC DC voltage dip, over-currents and trips of the STATCOM during and after system disturbances and faults, when its VAR support functionality is most required. In this paper, the integration and control of energy storage systems (ESSs), such as supercapacitor (ultracapacitor - UCAP) into a D-STATCOM (Distribution system STATCOM) is developed to mitigate such problems, enhance power quality and improve distribution system reliability. This paper develops the control concepts to charge/discharge the UCAP by the D-STATCOM, and validate the performance of an integrated D-STATCOM/UCAP system for improving distribution system performance under all types of system related disturbances and system faults - such as single-line to ground fault (SLG), line-line fault and 3-phase system faults. Simulation results of a 125 kVA D-STATCOM validate that integrated the D-STATCOM with 600 V, 1.0 Farad UCAP is suited for distribution system voltage regulation and voltage sag mitigation. In case of a system fault, UCAP based energy storage will aid to keep the D-STATCOM DC voltage constant and avoid over-current and trips of the VSC based D-STATCOM.

TL;DR: The proposed control strategy for the D-STATCOM not only eliminates effectively the oscillations of the active and reactive powers exchanged between the wind generator and the grid but also achieves the symmetrical and sinusoidal grid currents with less harmonics.

TL;DR: The advanced static VAr compensator (ASVC) as mentioned in this paper is based on the principle that a self-commutating static inverter can be connected between three-phase AC power lines and an energy storage device, such as an inductor or capacitor, and controlled to draw mainly reactive current from the lines.
