This paper introduces a new approach for scheduling security constraint unit commitment (SCUC) including wind farms. Because of uncertainty in wind power production, we tried to develop a new method for incorporating wind power generation in power plant scheduling. For this, wind power generation modeled with unit commitment in a non-linear optimization problem and simulated by submitting diffe...
Abstract: Deploying Distributed Generation (DG) units has increased due to yearly increase of electric energy demand and technological advancements beyond Smart Grid. Although, DGs offer several advantages such as reducing economic costs and environmental impacts, the operation of these units in power systems creates several problems. In this paper, optimal allocation and sizing of DG units in ...
Objectives: This research was conducted to compare the reaction of married people to marital conflict among three generations of women and two generations of men. Method: The study was a qualitative research and the target population was all married people belonging to last three generations living in Tehran in 2014. Sampling was conducted in two stages using convenience and purposive methods. ...
Entropy generation due to viscous incompressible MHD forced convective dissipative fluid flow through a horizontal channel of finite depth in the existence of an inclined magnetic field and heat source effect has been examined. The governing non-linear partial differential equations for momentum, energy and entropy generation are derived and solved by using the analytical method. In addition; t...
the mode of agronomic traits inheritance was investigated in safflower (carthamus tinctorius l.) in drought stress as a new report. five generation including p1, p2, f1, f2 and f3 that derived from the cross of il.111 (drought sensitive) ×mex.22-191 (drought tolerance) were used in a randomized complete block design with two replications. generation mean analysis was used to estimate genetic pa...
in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...
The effects of herd size, semen type, generation overlapping and breeding goal on genetic gain in Holstein cows were studied through stochastic simulation. Three levels of herd size (100, 200, and 400), two levels of semen type (unsexed and sexed), three levels of generation overlapping (low, average and high) and two levels of breeding goal (narrow and broad) were combined together to make 36 ...
One of the areas of development in higher education is the move towards benefiting from the third-generation university systems. Accordingly, the main purpose of this study was to explain the characteristics of a third generation university and to examine their achievement from point of view of administrators and faculty members at Shahid Bahonar University of Kerman. The current study was a qu...
Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. Also, because of power market and generators’ forced outages stochastic behavior, Monte Carlo Simulation is used for reliability evaluation. Generation r...
Purpose: The present study was conducted to identify the status of research on entrepreneurship and income generation in public libraries with a focus on creative economics. Method: The present study is a systematic study. The statistical population of this study was all the researches done in the field of creative economy in public libraries that have been published in connection with entrepr...
