This paper presents a novel approach in two-area interconnected power system for enriching the transient stability at perturbations. The challenging task in the interconnected system is to equalize the power production and load demand without changing the system parameters. Therefore, a sophisticated controller of flexible alternating current transmission system (FACTS) called distributed power flow controller (DPFC) is suggested to the two-area power system for enhancing the system stability. Furthermore, the resistive type superconducting fault current limiter (SFCL) is also suggested to employ with DPFC for alleviating the fault current, and power quality issues. In this work, three cases are investigated by using without auxiliary, SFCL, unified power flow controller (UPFC), SFCL-UPFC, and SFCL-DPFC on two-area multi-machine system. The objectives of the paper are to determine and evaluate the fault current, variations in voltage and inter-area oscillations, ascertain the performance of suggested techniques at diverse fault-clearance times, and find out the finest control method for different kinds of faults. The simulation outcomes disclose that the coordination of SFCL and DPFC yielded finer outcomes over other control approaches.

本文提出了一种在两区域互连电力系统中丰富扰动瞬态稳定性的新颖方法。互连系统中具有挑战性的任务是在不更改系统参数的情况下均衡发电量和负载需求。因此，在两区域电力系统中建议使用一种复杂的柔性交流输电系统（FACTS）控制器，称为分布式潮流控制器（DPFC），以增强系统稳定性。此外，还建议将电阻型超导故障电流限制器（SFCL）与DPFC一起使用，以减轻故障电流和电能质量问题。在这项工作中，通过在两区域多计算机系统上不使用辅助设备，SFCL，统一潮流控制器（UPFC），SFCL-UPFC和SFCL-DPFC来研究三种情况。本文的目的是确定和评估故障电流，电压变化和区域间振荡，确定建议的技术在不同故障清除时间的性能，并找到针对各种故障的最佳控制方法。仿真结果表明，与其他控制方法相比，SFCL和DPFC的协调产生了更好的结果。
