in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...
This paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. The hybrid DC power sources are connected to grid using power electronic converters include DC-DC converter and grid connected voltage source inverter. The power from hybrid power sources is controlled during voltage sag by designing of control strategy for DC-DC converter....
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

in emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. the flexible ac transmission system (facts) controllers can play an important role in the power system security enhancement. however, due to high capital investment, it is necessary to locate these controllers optimally in the power system. facts...
بررسی تاثیر ادوات facts بر بهبود پایداری استاتیکی ولتاژ به دو روش تحلیل مقادیر تکین و پخش بار پیوسته
برای بررسی پایداری ولتاژ روش های بسیاری پیشنهاد شده اند که هر کدام دارای مزایا و محدودیت هایی هستند. انتخاب روش و شاخص مناسب خود یکی از مهمترین بخش های یک مطالعه دقیق در این زمینه است. در این پژوهش دو روش رایج در پژوهش های پایداری ولتاژ برای بررسی تاثیرات دو عنصر facts جبرانساز استاتیکی سنکرون statcom و جبران ساز سری کنترل شونده با تریستور بر پایداری ولتاژ به کار گرفته شده اند و نتایج آنها با ی...
