In this paper to assess the environmental efficiency of electric power companies two-stage approach has been used Which means that the first step is to calculate the environmental efficiency score of electric power companies with Slack-Based Measure during the period (2004-2014). Then, the second step various factors effects have been evaluated on environmental efficiency by using Tobit and Ord...
Electric power industry should play a bigger role in energy conservation and emission reduction, while the ecosystem degradation rises because of the shortage of energy, the greenhouse effect and the environmental pollution. Power generation dispatch is the key practice in electric power industry. In this paper, the value based dispatch theory is proposed, which assign the value of the natural ...
Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...
این پایان نامه مشتمل بر تحقیقاتی در زمینه قابلیت اطمینان سیستم های توزیع و تحلیل و ارزیابی قابلیت اعتماد در شبکه های توزیع با در نظر گرفتن واحدهای تولید پراکنده برق می باشد. واحدهای تولید پراکنده عبارت از تولید کننده های کوچک برق هستند که محدوده ظرفیت شان بین 15 kw تا 10 mw است و به منظور فراهم کردن توان الکتریکی مصرف کننده ها در کل سیستم قدرت پخش شده اند. این واحدهای تولیدی با توجه به ظرفیت شا...
