a fuzzy logic controlled bridge type fault current limiter for transient Stability Augmentation of multi machine power system
Power and Energy Society General Meeting, 2016Co-Authors: Mohammad Ashraf Hossain Sadi, Mohd. Hasan AliAbstract:This paper proposes a fuzzy logic controlled bridge type fault current limiter (FCL) to enhance the transient Stability of multi-machine power systems. The transient Stability performance of the fuzzy logic controlled bridge type FCL is compared with that of another static nonlinear controlled bridge type FCL. The total kinetic energy (TKE) of the generators in the system is used to determine the transient Stability enhancement index. Also, the critical clearing time has been presented as a Stability limit. Instead of conventional reclosing, the optimal reclosing of circuit breakers is considered. Simulations are performed by using the Matlab/Simulink software. Simulation results of both permanent and temporary faults at different points of the IEEE 30 bus power system indicate that the fuzzy logic controlled bridge type FCL can enhance the transient Stability of the system well. Also, the performance of the proposed fuzzy logic controller is better than that of the static nonlinear controller.

transient Stability Augmentation of pv dfig sg based hybrid power system by parallel resonance bridge fault current limiter
Electric Power Systems Research, 2016Co-Authors: Md Kamal Hossain, Mohd. Hasan AliAbstract:Abstract This paper proposes a parallel-resonance bridge type fault current limiter (PRBFCL) to augment the transient Stability of a hybrid power system consisting of a photovoltaic (PV) power generation source, a doubly-fed induction generator (DFIG)-based wind energy system, and a synchronous generator (SG). The PRBFCL is designed such a way that it can provide sufficient damping characteristics to the studied power system. The effectiveness of the proposed PRBFCL in improving the transient Stability and enhancing the dynamic performance of the hybrid power system is verified by applying both balanced and unbalanced faults in the power network. Also, its performance is compared with that of the bridge type fault current limiter (BFCL) and the fault ride through (FRT) schemes, i.e. FRT schemes of PV, DFIG, and with the AVR and governor of synchronous generator (SG). Some indexes are used to quantify the system performance. Simulation results obtained from the Matlab/Simulink software show that the proposed PRBFCL is effective in maintaining stable operation of the PV, wind generator, and synchronous generator during the grid fault. Moreover, the performance of the PRBFCL is better than that of the BFCL and the FRT methods in every aspect.

transient Stability Augmentation of pv dfig sg based hybrid power system by nonlinear control based variable resistive fcl
IEEE Transactions on Sustainable Energy, 2015Co-Authors: Md Kamal Hossain, Mohd. Hasan AliAbstract:This paper proposes three nonlinear controllers such as fuzzy logic controller (FLC), static nonlinear controller (SNC), and adaptive-network-based fuzzy inference system (ANFIS)-based variable resistive-type fault current limiter (VR-FCL) to augment the transient Stability of a large-scale hybrid power system consisting of a doubly fed induction generator (DFIG)-based wind farm, a photovoltaic (PV) plant, and a synchronous generator (SG). Appropriate resistance generation of the VR-FCL during a grid fault to provide better transient Stability is the main contribution of the work. The effectiveness of the proposed control methods in improving the transient Stability of the hybrid power network is verified by applying both balanced and unbalanced faults in one of the double circuit transmission lines connected to the system. Simulation results show that the proposed FLC-, SNC-, or ANFIS-based VR-FCL are effective in improving the transient Stability of the studied hybrid system. Moreover, all the proposed methods exhibit almost similar performance. Therefore, any of the methods can be chosen for the transient Stability enhancement of the hybrid power system.

transient Stability Augmentation of power system including wind farms by using ecs
IEEE Transactions on Power Systems, 2008Co-Authors: S. M. Muyeen, Mohd. Hasan Ali, Toshiaki Murata, Rion Takahashi, Junji TamuraAbstract:This paper presents a new method to enhance the transient Stability of multimachine power system including wind farms, when a severe network disturbance occurs in the power system. For this purpose, the energy capacitor system (ECS) composed of power electronic devices and electric double layer capacitor (EDLC) is proposed. The control scheme of ECS is based on a sinusoidal PWM voltage source converter (VSC) and fuzzy logic controlled dc-dc buck/boost converter using insulated gate bipolar transistors (IGBT). Two wind farms are considered to be connected to the power system. Two-mass drive train model of wind turbine generator system (WTGS) is used in the analyses as the drive train modeling has great influence on the dynamic characteristics of WTGS. Real wind speed data are used in the analyses to obtain realistic responses. Different types of symmetrical and unsymmetrical faults are considered as the network disturbance. Simulation results clearly show that the proposed ECS can enhance the transient Stability of wind generators in multimachine power system as well as their low voltage ride through (LVRT) capability.

A fuzzy logic-controlled superconducting magnetic energy storage for transient Stability Augmentation
IEEE Transactions on Control Systems Technology, 2007Co-Authors: Mohd. Hasan Ali, Toshiaki Murata, Junji TamuraAbstract:This paper presents a fuzzy logic-controlled superconducting magnetic energy storage (SMES) to improve the transient Stability of an electric power system. In order to see how effective the proposed fuzzy controlled SMES in improving the transient Stability is, its performance is compared to that of a conventional proportional-integral (PI) controlled SMES. Furthermore, a comparative study between the fuzzy controlled SMES and fuzzy controlled braking resistor (BR) is carried out. Simulation results show that the performance of fuzzy controlled SMES is better than that of PI controlled SMES. Again, the performance of SMES is better than that of BR. Finally, it can be concluded that the proposed fuzzy controlled SMES provides a very simple and effective means of transient Stability enhancement of electric power systems
