Adding Power to Systems Science in Rehabilitation

wind farm impact on generation adequacy in power systems

در سال های اخیر به دلیل افزایش دمای متوسط کره زمین، بشر به دنبال روش های جایگزین برای تامین توان الکتریکی مورد نیاز خود بوده و همچنین در اکثر نقاط جهان سوزاندن سوخت های فسیلی در نیروگاه های حرارتی به عنوان مهم ترین روش تولید توان الکتریکی مطرح بوده است. به دلیل توجه به مسایل زیست محیطی، استفاده از منابع انرژی تجدید پذیر در سال های اخیر شدت یافته است. نیروگاه های بادی به عنوان یک منبع تولید توان...

Adding Hardware Accelerators to Reduce Power in Embedded Systems

Not all functions are equally suited to trading circuits for frequency. Functions that operate in parallel run much faster when hardware is available to execute several steps simultaneously, which translates into greater performance for a given clock speed, but also into lower clock speed for a given performance level. Thus, the addition of hardware to a chip design can lower power demands whil...

Complex Science Application to the Analysis of Power Systems Vulnerabilities

Adding Incentives to Peer-to-Peer Systems

Modern peer-to-peer systems rely heavily on the willingness of users to distribute files to their peers. A selfish user can choose to download a file and consume resources without uploading in return. This form of free-riding plagues all currently deployed systems. We present a protocol for a BitTorrent-like system (i.e., in which only one file is being shared) that strongly discourages peers f...

Fault Type Estimation in Power Systems

This paper presents a novel approach for fault type estimation in power systems. The Fault type estimation is the first step to estimate instantaneous voltage, voltage sag magnitude and duration in a three-phase system at fault duration. The approach is based on time-domain state estimation where redundant measurements are available. The current based model allows a linear mapping between the m...
