The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....
The future distribution network comprising different energy carriers will include small-scale energy resources (SSERs) and loads, known as a Networked multi-carrier microgrid (NMCMG). This concept not only leads to an efficient reduction in operation costs, but also encompasses the energy transformation between gas and electric networks at combined nodes, as well as district heating networks. I...
We propose in this paper a novel configurable multi-power-rail pad that combines power supply support circuits and a digital input/output (I/O) buffers designed for a wafer-scale system. This wafer-scale platform includes a reconfigurable wafer-scale circuit, the wafer IC, comprising an alignment-insensitive surface that can be configured to interconnect any digital components manually deposite...
This paper explores the relay protection of power grid with large-scale wind access across globe. First, amplitude and attenuation characteristics short circuit current in different types turbines are analyzed, as well contributing factors to short-circuit farms. Second, fault corresponding strategies collector plant discussed. Then, view adaptability HVDC access, performance zero-sequence prot...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
وجود معمای امنیت و پایداری آن کشورها را متوجه منطقه، تهدیدات و بی ثباتی های موجود در آن کرده است. تسلط تهدید، رقابت، اختلاف و خصومت، رقابت های تسلیحاتی و اختلافات سیاسی و ائدولوژیک از موانع عمده ی شکل گیری امنیت پایدار در مناطق است. در این میان چرخه ی قدرت یکی از مهم ترین ویژگی های سیستم جهانی و منطقه ای است که تاثیر مستقیمی بر موضوع مذکور دارد. لازم به ذکر است، که انواع چرخه های قدرت، سبب شکل ...

System Dynamics Simulation of Large-Scale Generation System for Designing Wind Power Policy in China
In the past few decades, increasing growth of wind power plants causes different problems for the power quality in the grid. Normal and transient impacts of these units on the power grid clearly indicate the need to improve the quality of the electricity generated by them in the design of such systems. Improving the efficiency of the large-scale wind system is dependent on the control parameter...
