In this paper, a fuzzy logic controller is proposed for an application of HVDC link to stabilize the frequency oscillation in a parallel AC – DC interconnected power systems. When an interconnected AC power system is subjected to a load disturbance, system frequency may be considerably disturbed and becomes oscillatory. By utilizing the system interconnections as the control channels of HVDC li...

Problem statement: The critical clearing time provides very important role of the robustness in power system. The Static Synchronous Series Compensator (SSSC) has been accepted to be equipped in series with modern power system. This study presents the method to evaluate the Critical Clearing Time (CCT) of the system equipped with a SSSC. Approach: The parameter on SSSC is modeled in energy func...

نوسانات فرکانس پایین یکی از بحث های مهم در سیستم قدرت می باشد. اگر این نوسانات میرا نشوند، ممکن است پایداری سیستم را به خطر بیندازند. ادوات facts از جمله وسایلی هستند که میتوانند در میرا کردن نوسانات نقش داشته باشند. کنترل کننده یکپارچه پخش توان (upfc) از مهمترین این ادوات است که میتواند با جایابی مناسب در سیستم قدرت، میرایی نوسانات سیستم را افزایش دهد. دراین تحقیق ابتدا روشهای مختلف جایابی upf...
In this paper a new optimization algorithm, the biogeography based optimization (BBO) is employed to design a robust power oscillation damping (POD) controller using unified power flow controller (UPFC). The controller that is used to damp low frequency oscillation is designed over a wide range of operating points using two different objective functions. The obtained controllers are then verifi...
