Increased integration of photovoltaics (PVs) systems and charging stations for electric vehicles (EVs) has led to a substantial increase in the level voltage unbalance beyond acceptable limit. Ordinary regulation devices such as on-load tap changers (OLTCs) distribution static synchronous compensator (DSTATCOM) are sometimes incapable adequately addressing this issue without proper coordination...
The distribution systems are facing severe power quality problems due to the large number of three phase and single phase linear, non-linear loads. These loads may be supplied from three-phase ac mains with neutral conductor. This creates excessive neutral current, high reactive power and harmonic current burden, load unbalancing, poor voltage regulation, etc. A three-phase fourwire distributio...
We propose a modular multilevel converter (MMC) based three-phase four-wire (3P4W) split capacitor distribution static synchronous compensator (DSTATCOM), aiming at compensating unbalanced and reactive load currents. Due to the zero-sequence current compensation, circulating characteristics of 3P4W MMC-DSTATCOM are different from conventional MMCs. Moreover, distinct working principle MMC would...
This paper presents a nonlinear controller for a Distribution Static Compensator (DSTATCOM) of a microgrid incorporating the Distributed Generation (DG) units. The nonlinear control has been designed based on partial feedback linearization theory and Proportional-Integral-Derivative (PID) controllers try to adjust the voltage and trace the output. This paper has proposed a combination of a fuz...
A solar photovoltaic distribution static compensator (SPV-DSTATCOM) under partial shading condition (PSC) is studied using a single-stage, 3-phase grid-connected mode. Under PSC, the performance of SPV-DSTATCOM and addressed issues such as active current sharing, reactive power control, harmonic elimination. Rejection DC offset with PSC an issue when conventional Proportional Resonant (PR) cont...
This paper focuses on the control techniques employed for Distribution Static Compensator. Distributed static compensator is a device used for power quality improvement. Here we considered voltage source converter based distributed static compensator. It describes to control distribution Static Compensator employed at the distribution end. The phase shift control and AC bus /DC link voltage sch...
The harmonic mitigation using shunt active filters are most widely used in industrial and commercial applications. In this paper a Multi-Level Inverter is considered as DSTATCOM to compensate harmonics. The mathematical modeling of the system and design of the controller using synchronous reference frame theory is also presented. The nonlinear load generally known as diode rectifier load and an...
