We proposed voltage-sourced converter (VSC) with Pulse-width modulation (PWM) provides a faster control that is required for flicker mitigation purpose. The voltage regulation in the distribution feeder is improved by installing a shunt compensator. The proposed DSTATCOM is modeled and its performance is simulated and verified for power factor correction and voltage regulation along with neutra...

Non-linear controller is preferred to linear controller due to non-linear operation of DSTATCOM. System dynamic can be improved by regulating and fixing the capacitor DC voltage in DSTATCOM. The nonlinear control is based on exact linearization via feedback. There is a PI controller in this system to regulate DC voltage. In conventional scheme, the trial and error method is used to determine PI...

The paper intends to develop the artificial neural network control algorithm for the control of DSTATCOM for the improvement of power quality. The presence of nonlinear loads makes the voltage to be deviated and current to be distorted from its sinusoidal waveform quality. Thus harmonics elimination, load balancing and voltage regulation is the heavy task that has to be accomplished to maintain...

AbstractThis paper presents an investigation of five-Level Cascaded H – bridge (CHB) Inverter as Distribution Static Compensator (DSTATCOM) in Power System (PS) for compensation of reactive power and harmonics. The advantages of CHB inverter are low harmonic distortion, reduced number of switches and suppression of switching losses. The DSTATCOM helps to improve the power factor and eliminate t...

Power electronic device, nonlinear and unbalanced loads have given rise to power quality problem in distribution systems. Due to factors like competitive generation patterns in a deregulated electric grid and an increasing level of sensitive end user devices, it has become necessary to ensure both reliable and power quality to the end customer. One way to betterment the power quality is using a...

<span lang="EN-US">In this research paper, an inductively coupled distributed static compensator (IC-DSTATCOM) for three phase wire (3P3W) electric power distribution system (EPDS) is proposed. The contraction of quality (PQ) was marked as a perilous droop mode bump into direct (DC-DSTATCOM).

In this paper we propose fuzzy control of DC-link capacitor voltage of three-phase four-wire DSTATCOM for power quality improvement in distribution network. It is designed to compensate reactive power and to eliminate harmonic currents. DSTATCOM regulates the voltage at the point of common coupling (PCC) by injecting reactive power to the PCC. During load changes there is considerable variation...
