1 بازبینی تکنولوژی های FACTS و کاربرد های آن برای کیفیت توان در شبکه های هوشمند با سیستم های انرژی تجدید پذیر
سال انتشار: 2018 - تعداد صفحات فایل pdf انگلیسی: 13 - تعداد صفحات فایل doc فارسی: 45
در دو دهه گذشته، ظهور استفاده از منابع انرژی پراکنده و تجدید پذیر در شبکه برق چالش هایی را برای سودمندی و کیفیت توان، پایدار سازی ولتاژ و بکار گیری انرژی کارآمد، ایجاد کرد. مبدل های الکترونیکی قدرت به صورت گسترده ای برای ارتباط بین سیستم های انرژی ظهور یافته (با ذخیره انرژی یا بدون آن) و سازه های هوشمند با سیستم های انتقال و توزیع بکار می روند. سیستم های انتقال ac انعطاف پذیر (FACTS ها) و مبدل های منبع ولتاژ با کنترل کننده های دینامیکی هوشمند، به عنوان یک پایدار سازی و تجهیزات فیلترینگ قدرت برای افزایش کیفیت توان در حال ظهور هستند. همچنین، FACTSهای پراکنده نقش مهمی در بهبود ضریب قدرت، پایدار سازی انرژی، تقویت کیفیت توان، و تضمین پایدار سازی انرژی کارآمد و مدیریت انرژی در شبکه های هوشمند با منابع انرژی تجدید پذیر، ایفا می کنند. این مقاله یک برآورد از ابزارهای تکنولوژی FACTS و کاربردهای آن برای کیفیت قدرت و کارآمدی برای پایدار سازی سیستم انرژی تجدید پذیر، ارائه می‌کند.

2 State-of-the-art, challenges, and open issues in the integration of Internet of things and cloud computing
مسائل مربوط به وضعیت، چالش ها و مسائل باز در ادغام اینترنت اشیاء و محاسبات ابری-2016
The Internet of Things (IoT) is a paradigm based on the Internet that comprises many interconnected technologies like RFID (Radio Frequency IDentification) and WSAN (Wireless Sensor and Actor Networks) in order to exchange information. The current needs for better control, monitoring and management in many areas, and the ongoing research in this field, have originated the appearance and creation of multiple systems like smart-home, smart-city and smart-grid. However, the limitations of associated devices in the IoT in terms of storage, network and computing, and the requirements of complex analysis, scalability, and data access, require a technology like Cloud Computing to supplement this field. More over, the IoT can generate large amounts of varied data and quickly when there are millions of things feeding data to Cloud Computing. The latter is a clear example of Big Data, that Cloud Computing needs to take into account. This paper presents a survey of integration components: Cloud platforms, Cloud infrastructures and IoT Middleware. In addition, some integration proposals and data analytics techni ques are surveyed as well as different challenges and open research issues are pointed out.

3 EV fast charging stations and energy storage technologies: A real implementation in the smart micro grid paradigm
ایستگاه های شارژ سریع ev و فن آوری ذخیره سازی انرژی: اجرای واقعی در پارادایم شبکه میکرو هوشمند-2015
In the last years, electric vehicles (EVs) are getting significant consideration as an environmentalsustainable and cost-effective alternative over conventional vehicles with internal combustion engines (ICEs), for the mitigation of the dependence from fossil fuels and for reduction of Green-House Gasses (GHGs) emission. However, many challenges are still ongoing to their large scale implementation. Among them, the negative impact on the electrical grid operation in case of an uncoordinated contemporary charging of a huge number of EVs. In the recent literature different solutions are proposed for handling the peak demand of EVs and the related problems. One answer is offered by the implementation of EV charging strategies, through aggregation agents, for containing the impact on the grid, guaranteeing the quality ofthe service. The implementation ofa real charging strategy is strictly related to a deployment of smart-grid technologies, such as smart meters, Information and Communication Technologies (ICTs) and energy storage systems (ESSs). In particular ESSs are playing a fundamental role in the general smart grid paradigm, and can become fundamental for the integration in the new power systems of EV fast charging stations of the last generation: in this case the storage can have peak shaving and power quality functions and also to make the charge time shorter. In the present paper, an overview on the different types of EVs charging stations, in reference to the present international European standards, and on the storage technologies for the integration of EV charging stations in smart grid is reported. Then a real implementation of EVs fast charging station equipped with an ESS is deeply described. The system is a prototype, designed, implemented and now available at ENEA (Italian National Agency for New Technologies, Energy and Sustainable Economic Development) labs. A wide experimental activity has been performed on the prototype system in order to test its functionalities in the integration in a smart grid available at the same ENEA lab, including a smart metering system. The integration has been possible thanks to the use of a customized communication protocol, developed by the researchers and here described. The results of the experimental tests show that the system has a good performance in the implementation of peak shaving functions, in respect of the main distribution grid, making the prototype like a network nearly zero-impact system.
