Hydropower Energy Versus Other Energy Sources in Turkey

Abstract Hydroelectric energy is one of the major renewable energy resources in Turkey. Turkeys gross hydropower potential is estimated as 433–442 terawatt hours/year; that is equal to 1% of world and 14% of European hydropower potential. This article presents the historical development, potential, and current status of hydropower, and examines the current role hydropower is playing in Turkey, along with some of its inherent benefits and environmental aspects. The article shows that hydropower provides about 25% of Turkeys electricity generation and has the best performance with respect to energy payback ratio. Hydropower is an important renewable energy source for clean, sustainable, and cheap energy compared to some other energy sources used in Turkey, as well as the world. Development studies and investments in this sector should be increasingly supported.

Estimation of the beach bar parameters using the genetic algorithms

Abstract Waves, topographic characteristics and material properties are the most significant factors, which affect the sediment movement and coastal profiles. In this study, considering the wave height ( H 0 ) and period ( T ), the bed slope ( m ) and the sediment diameter ( d 50 ), the cross-shore sediment movement is investigated using a physical model and obtained 80 experimental data for offshore bar geometric parameters. The experimental results are also evaluated by the genetic algorithms (GAs) that are limitedly employed in coastal engineering applications. The results of GAs model and equations cited in the literature are compared with the experimental results. It is concluded that estimates of bar parameters by the GAs give a better estimation performance with respect to other conventional methods.

Two different power control system load-frequency analysis using fuzzy logic controller

With two different regions of a Load Frequency control of power systems using fuzzy logic-based controller are examined. With a load of any change in the frequency of the power system investigated how affected. Then Fuzzy Logic Controller (FLC) changes, such as what is observed in using the system. The system has two different control area power system small signal model in Matlab / Simulink computer simulation program was created. FLC in the control and Integral Controller has been using the system. This produces two different results are compared with the controller.

The Total Electricity Energy Production of the World, European Union, and Turkey: Projections and Comparison

Abstract This study aims to forecast the worlds, European Unions (EU), and Turkeys electricity energy generation until 2030. For this purpose, the electricity energy sector of the world, EU, and Turkey was overviewed from past to present. The total electricity energy generation for the world, EU, and Turkey were then modelled by using historical energy generation data as years with regression analysis. Data from 1970 to 2004 for Turkey and data from 1980 to 2004 for the world and EU were used for the projections. Electricity energy productions have been forecasted up to year 2030. According to the results, it is determined that cubic (R2 = 0.997) and linear (R2 = 0.993) models for projection of the worlds and EUs electricity energy generation, respectively, is fitness while the quadratic (R2 = 0.996) model fits for the projection of Turkeys total electricity energy generation and Turkey will have 0.995% of the worlds electricity energy generation in 2030, while the EU will have 8.41% within the worlds electricity energy generation in 2030 if the current trend continues.

Total Electricity and Hydroelectric Energy Generation in Turkey: Projection and Comparison

Abstract The main goal of this study is to forecast total electricity and hydroelectricity energy generation using historical electricity energy production data in order to determine the future level of electricity and hydroelectricity energy generation in Turkey. For this purpose, Turkeys electricity energy sector was reviewed during the period of 1940–2005. The total electricity and hydroelectricity energy generation were then modelled using historical energy generation data as years with regression analysis. Additionally, the portion that hydroelectric energy generation of Turkey has within total electricity energy production and probable meeting capacity of Turkeys hydroelectric potential of its future total demand was determined. According to the results, it is deduced that hydropower energy will have portion of 13.6% within the total electricity energy generation in 2030. In addition, it is concluded that the whole of Turkeys technical and economical hydroelectric energy potential that is equal 129.9 billion kWh will be used in the year of 2102 if the current trend continues.

A LabVIEW based submarine depth control simulator with PID and fuzzy controller

LabVIEW is one of the popular simulation program in the academic and industrial applications. In this paper, online simulator for the depth control of a submarine has presented. In order to keep the submarine at a certain level below the sea surface, a fuzzy logic controller (FLC) as a major control unit was designed and employed with LabVIEW Control Design and Simulation Toolkit. Also comparison between fuzzy logic (FL) and PID controlled system was presented. Simulation results show that system has better settling time and no overshoots with FLC.
