در این پروژه، با تعیین میزان تولید منابع پراکنده در کنار کنترل ولتاژ/توان راکتیو و تجدید آرایش سیستم برای سطوح بار مختلف، بهره برداری از سیستم توزیع برای تحقق اهدافی چون کاهش تلفات انرژی سیستم، بهبود شاخص پایداری ولتاژ و تقسیم مناسب جریان توان بین فیدرها انجام می شود. به این منظور یک مسیله بهینه سازی تعریف و با توجه به تعداد فراوان متغیرهای کنترلی و حالت گسسته آن ها، الگوریتم حلی بر مبنای روش ج...
چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
1/4 My research interests are in the areas of power system optimization and control, grid integration of distributed energy resources including renewables and energy storage systems (ESS), distribution system optimal voltage regulation, and power markets and power system economics. I conduct fundamental and applied research on efficient grid integration of distributed energy resources from both...

Electricity consumption has been rising with an average annual growth of 7% in Iran and the imbalance in production and consumption has caused power outage crisis and economic losses. More than 50% of peak electricity demand is related to the household sector, so the household sector can be considered as the most effective component of the electricity crisis. Investment costs for the constructi...

in the sector of electricity production, the existence of investment resources limitation and environmental factors are the main factors that influence this process. the reduction of costs and the destructive impacts of environmental have been always mentioned by specialists. consequently, the drasticality of the environmental protection and the electric-energy production lead to focus on solar...
In this paper, we introduce and study a new extension of Lomax distribution with four-parameter named as the Marshall–Olkin alpha power (MOAPL) distribution. Some statistical properties are discussed. Maximum likelihood estimation (MLE), maximum product spacing (MPS) least Square (LS) method for MOAPL parameters A numerical using real data analysis Monte-Carlo simulation performed to compare be...
In this paper, we investigate the unique institution of the Japanese press industry called kisha club system, which is deemed as the symbol of media capture by the government, and collusion in the media industry. By tracing through its history, we show how the institution has developed as a result of the government’s attempt to control the media, and the media’s incentive to use the alluring op...
