This paper aims at investigating the problem of Load Frequency Control (LFC) in interconnected power systems in order to obtain robustness against uncertainties. A design method for a robust controller, based on Quantitative Feedback Theory (QFT), has been presented in this paper. For a two-area power system, the simulation results show that the system response with the proposed QFT controller ...

Abstract: In the present work, we focus on the study of dynamic behavior of an interconnected two-area power system and a scheme for improvement of response for the same. Here, two-area system with one non-reheat thermal units & one reheat thermal units is considered. The frequency and tie-line power deviation of two units are studied using MATLAB-SIMULINK in continuous time domain and also in ...

نخستین گام در راستای تحلیل و ارزیابی ریسک‌های زنجیره تأمین شناسایی این ریسک‌ها است. روش‌های مرسوم بر اساس فیلترهای دستی یا خودکار داده‌­محور ارائه شده فیلتر به‌­دلیل محدودیت‌های نمونه‌گیری دارای مشکلات اعتبارسنجی هستند از طرف دیگر مبتنی داده، داده‌های ریسک که پیچیده مبهم هستند، عملکرد ضعیفی دارند. برای پرکرده خلل پژوهشی، پژوهش، چارچوبی تعاملی بین تحلیل‌­گر ماشین حجم وسیعی حوزه مواد غذایی با است...

Reservoir recovery processes involve complex mass and heat transfer between the injected fluid and the resident rock-fluid system. Thermal-compositional reservoir simulators can be used to plan such displacement processes, in which the phase behavior is computed with an Equation of State (EoS). These thermodynamic-equilibrium computations include phase-stability tests and flash calculations, an...

The analytical theory of one dimensional, dispersion free miscible displacement of oil by injection gas with nc component has shown that: the MMP is the lowest pressure at which any one of the initial oil, injection gas or crossover key tie lines becomes critical, which means that its length approaches to zero. In this paper, we propose a method for a solving multi component syst...

Scholars around the world have studied electronic word of mouth (eWOM) heavily in past decade. However, despite extensive knowledge effect eWOM on consumer behavior, there is still a lack understanding how source shapes those behaviors. There are many sources eWOM, influence which may different outcomes when it comes to consumers’ purchase intentions. Moreover, most studies measured social tie ...

OBJECTIVE The angiopoietin (Ang)-Tie-2 system plays a critical role during fetal and adult angiogenesis. Herein, we explored the Tie-2 shedding-related molecular mechanisms and the pathophysiological significance. METHODS AND RESULTS By using a mouse hindlimb ischemia model, we observed dissociated expression between the full-length Tie-2 (fTie-2) protein and Tie-2 mRNA in thigh muscles 1 day...
