Published: November 2018

Turkey wants to become the world’s 10th largest economy in the 100th anniversary of the foundation of the republic of Turkey. In order to achieve this goal, there are many breakthroughs in the political, economic and in energy fields. Turkey’s installed power capacity was 85000 MW in 2017 but installed power of 125.000MW is targeted to achieve the objective of 2023 targets. The government is aiming to increase the total production of renewable energy share by 30% in 2023, while foreseeing the increase in capacity due to nuclear and fossil fuel consumption. Targets for different technologies are 34000 MW hydroelectric, 20000 MW wind energy, 5000 MW solar energy (photovoltaic and condensed solar energy), 1000 MW geothermal energy and 1000 MW biomass. Capacity utilization in hydroelectricity is 62%, wind power is 14%, and geothermal power is 33%. The total installed capacity of Biogas, Biomass, Waste Heat and Pyrolytic Oil Power Plants is 530 MW. Theoretical total power capacity of the solar energy for Turkey as 300 TWh/year and reached 45% of the 2023 target in 2017 in the last three years. However, it is estimated that the targets of 2023 in solar energy can be exceeded. Government offers attractive incentive packages for renewable and other energy sector to achieve 2023 goals. In order to encourage domestic production, a total of 2000 MW wind and solar energy installation bid was carried out in 2017. This contract is expected to make Turkey as energy hub both in terms of installation and technology. In this study, Turkey’s renewable energy potential, and energy strategies and breakthroughs for this were investigated and discussed.

Published: November 2018

The integration of hybridized renewable energy sources (RES) with AC/DC converters has become the focus of the 21st century for green Information Communication Technology (ICT) applications such as the data center. As the data traffic grows exponentially, the corresponding demand for energy to drive the growth becomes a great challenge and considering the environmental impact, a hybrid renewable energy system is favored for eco-sustainability and economic reasons. This is especially true for data centers which represent a dominant share of the total power in cellular networks. This paper evaluates the actual performance of a fuel cell in a renewable energy hybrid system considering the hybridization of photovoltaic (PV), Wind, Fuel Cell, and battery storage system with a choice of a half-grid mode. The reduction and the absence of available PV power by shading and rainy conditions will be easily reduced by the compensation of the other renewable sources. The modeling and simulations are performed using HOMER software. The results show the effectiveness of the proposed system as the energy supply is less intermittent and more stable.

Authors: Fitsum Bekele Tilahun , Ramchandra Bhandari , Menegesha Mamo
Published: November 2018

Heavy dependence on traditional fuels as well as connection to a significantly unreliable and inefficient grid (with about 20% energy loss) characterizes the Ethiopian industry. On the contrary, the country has many solar-suited industries for process heat augmentation in the low-to-medium temperature ranges. Thus, if properly designed and operated, solar thermal could give an opportunity for an efficient and cleaner alternative in these industries. This paper presents agent-based modeling (ABM) for an integrated optimization and demand side management (DSM) framework for solar-assisted industrial heating under varying load and weather condition. To demonstrate the validity and practicality of the proposed solution, a case study was conducted on Ethiopian textile industry. A payback period of 5.3 years and solar fraction of 66.7% was identified for an optimized system. Further with the implementation of DSM to guide the production policy of the industry, a 7.5% and 8.4% improvement in payback and solar fraction was achieved.

Authors: Raed Althomali , Mohammed Alsumiri
Published: November 2018

Linear generators are one of the most efficient sea wave’s energy extraction setup. In the linear generator setup the energy is taken out by the vertical movement of waves. In most of the energy conversion systems, the energy is extracted by rotating motion by using the rotary generators. This paper is based on the prototype design of moving coil linear generator. The analysis of the prototype is done using the Maxwell finite element software. Finite-Element-Method (FEM) is used to analytically calculate the induced voltage and cogging forces. In this research, the FEM model of a coreless moving coil P.M linear generator has been outlined with an air cored stator. The main aim of the prototype is to convert marine energy directly without conversion from one form of motion to another, in regions the wave height is around 50 cm. A detail machine design formula is derived for the bases of initial prototype design. Prototype is modelled using Maxwell 2D FEM analysis. Hardware setup results were discussed to confirm the design, and to explore the working of the prototype as a generator. The movement of coils is accomplished by buoyancy mechanism of sea waves. The EMF generated is 6 Vp-p according to finite element simulation software. The prototype is able to generate EMF of about 2.5 Vp-p.

Background: Narcotics addicts must undergo rehabilitation to get recovery. During the recovery process, families bear both economic and social burdens. This study aimed to find out how the burden of families with family members who experienced relapse was and what factors could exacerbate it. This study used cross-sectional study design by measuring family burden as an outcome. The samples in this study were 168 families having family members who abused narcotics and experienced relapse. Multivariate analysis with multiple linear regression showed that the factors exacerbating the family burden of narcotics abusers were the family member’s age of first use of narcotics and drinking habits (dominant factor) with R = 0.964, R Square = 0.929, Adjusted R Square = 0.928 and Durbin Watson = 0.982. Narcotics abusers who experience relapse will increase the family burden. Factors that aggravate the family burden are as follows: first time using narcotics at an early age and alcohol drinking habit. Therefore, we must prevent the use of narcotics as early as possible among the entire community and stop drinking alcohol.

Authors: Hargiyatno Ignatius Tri , Utomo Suyud Warno , Sue Rauf Achmad , Wudianto
Published: November 2018

This paper aims to describe the Fish Aggregating Devices (FADs) fisheries in Indonesia and its relation to sustainable fisheries management. On tuna fishing, FADs are widely used as a tool to attract fish. FADs uncontrolled development is feared to have an impact on the sustainability of fish resources. We found that most of the fish caught around FADs are still juvenile. Deployment FADs can also interfere with the swimming pattern of tuna resources. This is negatively affecting the sustainability of tuna resources. However, from the social and economic aspects, FADs provide significant benefits for fishing communities. The Government has imposed regulations on FADs but not yet implemented. The objective of SDG's in the management of tuna fisheries associated with FADs can be implemented through the application of RFMO regulations. Findings from this paper can be used for policy recommendations for the management of sustainable FADsfisheries.

Published: November 2018

Further growth in renewable energy and planned electrification and decentralization of transport and heating loads in future power systems will result in a more complex unit commitment problem (UCP). This paper proposes an adaptive approach to load leveling problem using novel dynamic models based on the Volterra integral equations of the first kind with piecewise continuous kernels. This approach employs a direct numerical method. The considered collocation-type numerical method has the second-order accuracy and enjoys self-regularization properties, which is associated with confidence levels of system demand. This adaptive approach is suitable for energy storage optimization in real time. The efficiency of the proposed methodology is demonstrated on the Single Electricity Market of the Island of Ireland.

Published: November 2018

Geoecological problems of lithosphere protection in transport construction are of great importance nowadays. The article deals with the research of the new lithosynthesis technology which can be used for geosphere protection in transport construction. Lithosynthesis is a new method of geosphere purification by means of engineering structures and building materials. The main aim of the paper is to show a possibility to restore lithosphere using mineral artificial stones of different nature, e.g. foam concrete or phosphates. Both theoretical, namely thermodynamic, method and experimental one are used in the study. Two techniques of lithosynthesis are demonstrated in the paper. The first technique is to apply so-called the “stone sponge” to absorb pollutions and detoxicate them. The second technique is formation of the artificial phosphate stone to detoxicate pollutions during hardening. The level of concentration of heavy metal ions to be detoxicated by means of foam concrete lithoreactions is determined. The study suggests creation of a new lock surface, e.g. through sols’ use, after detoxication of pollutions.

The paper discusses the traction parameters of an electric locomotive of a new generation. The existing schemes of sections served by electric locomotives and locomotive crews at the studied railway operating domain are presented. A comparison of the main parameters of DC and single-phase AC electric locomotives, the operation of which is currently organized at sections with trains of estimated weight in the long-term traction mode on the ground slopes with different steepness, is made. The scheme of the proposed organization of operation of dual-voltage electric locomotive and locomotive crews is presented. Traction parameters of a dual-mode electric locomotive are calculated, taking into account the plan and profile of the track at the proposed sections of operation, the specific basic resistance to the movement of the locomotive and the train at the estimated speed, the specific accelerating and decelerating forces of the train. When dual-mode electric locomotives are put into operation, it will be possible to reduce the fleet of locomotives in operation, the number of locomotive runs due to their lengthening, and the number of locomotive crew relief points, reduce the transit time of freight trains, increase technical and service speed, average daily mileage and average daily performance of the locomotive, reduce power consumption for traction. The operation of such electric locomotives contributes to the development of technologies for rail traffic management and the improvement of quantitative and qualitative indicators of various railway facilities.

The paper is devoted to the solution of the problem of increasing the energy efficiency of the transportation process on the electrified sections of the railways. The task is considered in the aspect of energy efficiency when comparing forecasted traffic schedules with each other and assessing the effectiveness of implementing the forecasted and executed schedule of train traffic at the section. The basis for the calculations is a simulation modeling of the interaction between the electric rolling stock and the traction power supply system at the sections with different track profiles. Simulation modeling was carried out for the conditions of changing the traffic schedule of freight trains and maintaining the amount of traffic and the amount of work unchanged. The results of the change in the amount of electric power for traction and the level of unbalance of energy for existing sections of constant and alternating current are used as the basis for construction of approximating models, in the function of which regression and neural network models are used. Comparison of the results of approximation of the considered models for the estimation of changes in amount of electric power for traction and unbalance is made. Models with the best results of approximation to simulation results are determined.

Published: November 2018

The paper is devoted to the simulation of the test complex designed for energy-efficient load testing of induction machines by the method of mutual load with the exchange of electrical energy through the network. It is noted that for other similar test schemes, the mathematical model will have a slightly different form, but it will be identical in terms of asynchronous machines, network and frequency converter. The compiled mathematical model of the test complex allows studying the variable parameters of the system in all elements of the test scheme in static and dynamic modes of operation as well. The synthesized mathematical model can be used to determine the parameters of the equipment in the designed test complexes if the parameters of the test and load machines are known. The results of simulation of the test complex for the given parameters of the test and load induction machines are obtained.

The article considers a control system for transportation of persons with disabilities and physically challenged people with the preset level of locomotion. This system is built with the help of modern tools of business modeling. A review of study results performed by the authors in the sphere of navigation showed that in spite of availability of modern navigation devices there are no easy-to-use indices reflecting route and vehicle accessibility. The authors developed a system of numerical evaluation of accessibility that will reflect a level of structure or service accessibility at various stages of adaptation, and will be easily understood by handicapped persons. This system can be used to build routes with the set level of passenger’s locomotion, to provide statistic observations and manage the transportation system.

Urbanization continues. There is an outflow of population from small cities and towns to large ones. According to some estimates, 60% of the world's population will live in cities by 2060 (now 50%). The middle class is growing, and there are more and more people who buy cars. Consequently, the load on urban infrastructure and roads is increasing. The high number of traffic jams leads to negative consequences: the delay in the delivery of goods, the late arrival of people to work, etc. On the other hand, despite the best efforts of manufacturers, transport continues to pollute the atmosphere. Technologies continue to develop rapidly, new business models, rules of doing business in transport and ways to use it are emerging. Recently, there has been the emergence of such innovations as car sharing (the use of cars that are freely available in the city), various types of taxis that can be called up using a mobile phone, and improved urban public transport. In addition, the most current urban trends are the development of pedestrian areas in large cities, non-motorised transport, and bicycles.
