In this paper, a new topology for Interline Dynamic Voltage Restorer (IDVR) is proposed. This topology contains two direct three-phase converters which have been connected together by a common fictitious dc-link. According to the kind of the disturbances, both of the converters can be employed as a rectifier or inverter. The converters receive the required compensation energy from the gird thro...

In the contemporary distribution network, unbalanced and harmonic distortions have been considered some major power quality problems, which escalated especially due to high penetration of nonlinear loads. This study first analyzes dispute around distortion restraint grid-connected unbalanced/harmonic current suppression quantitatively proposes a distributed control strategy that facilitates an ...

The bipolar low-voltage DC (LVDC) distribution system has become a prospective solution to better integration of renewables and improvement efficiency reliability. However, it also faces the challenge power voltage imbalance between two poles. To solve this problem, an interface converter with asymmetrical operating capabilities is applied in paper. steady-state models LVDC equipped grid connec...

Leg capacitor energy balancing control is one of the crucial issues for stable operation a cascaded H-bridge (CHB) converter. Because this topology inherently consists numerous submodule cells with DC capacitors, cell voltages and leg instantaneously fluctuate depending on sequence CHB In general, wye-connected CHB-converter-based static synchronous compensator (STATCOM) utilizes zero-sequence ...

This paper presents an analysis of the three-phase self-excited induction generator (SEIG) with staticcompensator {STATCOM) as a voltage regulator. Current controlled voltage source inverter (CC-VSI) is used as STATCOM, which provides fast dynamic response to maintain constant voltage at SEIG terminals during severe load perturbations and acts as a source and sink of reactive power. The perform...

This paper presents modeling and control of a microgrid based on hybrid renewable energy sources including Photovoltaic (PV), Fuel Cell (FC) and Battery Energy Storage (BES). The overall configuration of the microgrid including dynamic models of PV, FC, BES and its power electronic interfacing are briefly described. Then controllers design methodologies for power electronic converters in order ...

Fixed speed induction generator (FSIG) having high asymmetrical fault percentage than variable speed. Even though there are different ways to control these faults StatCom control method to compensate reactive power is one of the useful and highly beneficial method. In this paper the FSIG wind farm is observed under unbalanced grid fault with StatCom connected to it with the help of MATLAB simul...

This paper describes a DC isolated network which is fed with Distributed Generation (DG) from photovoltaic (PV) renewable sources for supplying unbalanced AC loads. The battery energy storage bank has been connected to the DC network via DC/DC converter to control the voltage of the network and optimize the operation of the PV generation units. The PV arrays are connected to the DC network ...
