About Me

Was born in Natore, Bangladesh, in 1996. Obtained my Bachelor of Science degree in Electrical and Electronic Engineering (EEE) from the Rajshahi University of Engineering and Technology (RUET), in 2019. My research interests include renewable energy systems, microgrids, ride through capability augmentation, and nonlinear controller design and its applications. Very passionate about research and intend to build a career on it. My hobbies are web designing, photography, cinematography and reading lots and lots of books, specially thriller novels. Love to collect books and dream to have my very own personal library one day.

A Capacitive Bridge-Type Superconducting Fault Current Limiter
to Improve the Transient Performance of DFIG/PV/SG-based Hybrid Power System

IEEE Transactions on Applied Superconductivity

This paper proposes a capacitive bridge-type superconducting fault current limiter (CB-SFCL) to address the most concerning issue with the grid connected hybrid power system by improving the transient performance. The hybrid system incorporates a doubly fed induction generator (DFIG) based wind farm, a solar photovoltaic (PV) system and a synchronous generator (SG) based power system. The CB-SFCL incorporates a high temperature superconductor (HTS) along with a power capacitor to provide adequate reactive power support before and after the fault. The capacitor is kept inactive during normal operation by a control circuit to ensure a seamless operation. During fault, the capacitor gets connected in series with the HTS and suppress the fault current. The performance of the CB-SFCL is investigated by proper graphical and mathematical analyses and conclusions are obtained by comparing them with that of the conventional bridge-type superconducting fault current limiter (BSFCL) and a capacitive bridge-type fault current limiter (CBFCL). The analyses support the theoretical superiority of the CB-SFCL over the BSFCL and the CBFCL by a satisfying margin.

Transient Performance Augmentation of DFIG Based Wind Farms by
Nonlinear Control of Flux-Coupling-Type Superconducting Fault Current Limiter

IEEE Transactions on Applied Superconductivity

Any fault related to grid is a matter of great concern for doubly fed induction generator (DFIG) based power system as DFIGs stator windings are connected to the grid directly. To augment the transient performance of the DFIGs, superconducting fault current limiter (SFCL) is a certified device. To boost the performance of a flux-coupling-type SFCL (FC-SFCL) by ensuing the adaptive use of fault current limiting impedance based on fault severity, rather involving the full impedance unnecessarily, a nonlinear controller (NC) for FC-SFCL (NC-FC-SFCL) is presented in this paper. Reason behind choosing a straightforward NC for this work is to have simple implementation capability with the full flavor of a nonlinear controller. Effectiveness of the NC-FC-SFCL is compared with conventionally controlled FC-SFCL for various fault scenarios. Simulation results suggest that, NC-FC-SFCL can improve the overall fault ride through (FRT) capability which is verified both by graphically and numerically. Additionally, this effective use of the fault limiting impedance guarantees better transient sub-synchronous resonance (SSR) performance, and exhibits better total harmonic distortion responses.
