[ 1 ] - Presenting a new method for charging and discharging PHEVs for improving in electrical parameters of the network
Problems with the cost and pollution of fossil fuels have increased the incentive to operate on electric vehicles. However, the use of these vehicles is a challenge due to the additional loads which imposed on the power grid. Accordingly, a method has been proposed to improve the electrical parameters of the network including losses and voltage profiles by optimally managing the charge and disc...
[ 2 ] - Detection of power oscillation and simultaneous faults using Clark transform
Distance relays are widely used to protect transmission lines. Sometimes, in these lines due to the occurrence of the oscillation of the power, the impedance calculated in the distance relay enters into its functional zones and leads to the cutting off of the lines. This issue can cause global power outages. Accordingly, in this paper, a Clark-based method for detecting the oscillation of power...
[ 3 ] - Allocation of Distributed Energy Resources for Microgrid Optimal Scheduling Considering Uncertainty
In this paper, a microgrid including a solar panel, a battery energy storage system and a diesel generator as the backup source are optimally is designed. The microgrid is considered as a part of a distribution network, that could be considered as local area. As microgrids can operate in grid-connected mode, the proposed algorithm investigates the minimization of the distribution network power ...
[ 4 ] - تشخیص جریان هجومی و جلوگیری از عملکرد بی‌مورد رله دیفرانسیل با استفاده از شکل‌های لیساژور جریان
جریان هجومی همدردی که در ترانسفورماتورهای سری و موازی اتفاق می‌افتد، می‌تواند دو مشکل عمده را در حفاظت از ترانسفورماتورهای قدرت ایجاد کند. اولین مشکل این است که سیستم حفاظت از ترانسفورماتور ممکن است به علت افزایش زیاد جریان عملکرد نادرست داشته باشد. دوم ممکن است وقتی یک سیستم حفاظت مشترک برای ترانسفورماتورهای موازی طراحی می‌گردد، موجب شود که جریان ورودی خط که حاصل جمع برداری دو جریان ورودی است...
