<p><strong>Abstract.</strong> Today, countries are shifting their energy policies towards to renewable energy sources. The main reasons for this can be summarized as the reduction of fossil fuel resources, resulting in cost increase and their harmful effect on the ecological balance. Since renewable energy sources are both economical and eco-friendly, for countries which have high solar energy potential such as Turkey, it is reasonable to direct their energy policies to solar energy which is a renewable energy source.</p><p>In this study, the development of renewable energy legislation in Turkey, from past to present has been examined and implementation steps for the licenced and unlicensed generation of electricity from solar energy have been introduced. Ten impact factors have been identified as the first step for the implementation of the solar power plant site selection in Istanbul, which was determined as the pilot region. Impact factors weighted using Analytical Hierarchy Process (AHP) method. Concurrently, the weights of these determined impact factors were compared with the weights obtained by evaluating the results of the “Evaluation of Solar Energy Power Plant Site Selection Factors” survey conducted during the study. After obtaining the weights, the relevant data were collected and the necessary analyses were performed with the help of the GIS software and the most suitable places were provided for the solar power plant for Istanbul.</p>

AbstractRenewable energy sources have been placed as the key to facilitating to provide source of electricity generation. Solar power is one of the most preferable one among renewable energy sources due to the easy to generate in suitable environment. However, there are concerns with the location of solar power plants installation which causes low efficiency and ineffective use. Hence, determining the location for the usage of solar power sources is critical to mitigating those concerns. In addition, Turkey has been focused on investments on sustainable renewable energy sources and there are few studies which work on cities to reveal potential sources. In this study, GIS and intuitionistic fuzzy set based multi-criteria decision-making method is proposed for determining the most suitable areas for solar energy power plant potential site selection in Erzurum province, Turkey. Firstly, a solar energy power plant potential site selection map is made using a GIS program along with considering ecological risks and ecological criteria. Secondly, 20 districts of Erzurum are investigated in terms of 10 criteria (slope, aspect, solar irradiation, land use, wind speed, air temperature, air pressure, air humidity, land surface temperature and transmission line) using intuitionistic fuzzy sets. In these parameters the first time we looked the land use surface. The land use surface is affected the efficiency of the solar power plant. Finally, the comparisons of two methods are done to check consistency of results obtained. The results indicate that both approaches achieve same areas as the most suitable locations for solar power plants installations for Erzurum province in Turkey. The aim of this work is first to investigate possible locations for solar power plant installation using a mapping method, GIS, and then, Intuitionistic Fuzzy is applied to the problem to obtain optimum areas for solar energy. Also, more accurate results are provided comparing results of two methods, GIS and Intuitionistic Fuzzy. The results expose that 25,065.3 km2 for solar power plant suitable for solar power plan installation.

Currently, renewable energy is under review so that its use can be more widespread in the future. One of the renewable energy sources that are commonly used is solar energy through solar cell technology that can convert solar energy into electrical energy and then becomes one of the components that makes up the solar power plant. The use of the solar power plant can be interconnected with distribution networks in electric power systems, both medium-voltage networks and low voltage networks. In this study, a 3 MWp capacity of solar power plant was conducted with the medium-voltage network system of X City. This interconnection study consisted of power flow and short circuit studies using ETAP 12.6.0 software. The results of the power flow study show the voltage level of each bus has increased by 0.293%-0.926% after interconnection with the solar power plant system, with a value that still matches the SPLN 1:1978 standard of 90% to 105%. Besides, the results of short circuit study show the value of the three-phase short circuit fault current experienced a change in value that is not too significant, with an increase of 1-37 A and a decrease of 1-5 A, with a value that is still according to the protection component rating standard of 25 kA.

The Future

The future of European energy is moving towards a single European electricity market and an increasing share of renewables in the overall production mix. After the expiration of governmental incentive measures, power plants based on renewable energy sources will enter the liberalized market, where electricity prices will largely depend on the production of renewable energy sources. In order to achieve the maximum possible profit of the power plant under such conditions, it is necessary to consider the possibility of investing in solutions that are less represented today, but with the prospect of being more profitable in the future. Such a solution is a solar power plant consisting of vertically placed bifacial modules whose active surfaces are oriented in the east-west direction. This configuration of the power plant can achieve higher production in periods of high prices, and thus higher profits from the sale of electricity. On the other hand, such a solution is more expensive than a standard solar power plant with monofacial modules. In this paper, a comparison of return on investment in a bifacial power plant and a monofacial power plant with existing and prospective market conditions is performed. PVsyst software was used to analyze the solar potential and production profiles of photovoltaic power plants. The influence of solar power plant production on the price of electricity was investigated on the example of Germany. Based on this research, a prognostic model of the daily price diagram on the unified European market until 2040 was formed which served for the analysis of the profitability of investments in the two considered variants of the solar power plant realization.

Terbatasnya energi fosil di Indonesia menyebabkan adanya pengembangan energi baru terbarukan. Energi terbarukan merupakan energi non-fosil yang berasal dari alam. Pemanfaatan energi surya bisa dilakukan dengan membangun Pembangkit Listrik Tenaga Surya (PLTS). Perencanaan PLTS menggunakan sistem on grid, sistem masih terkoneksi dengan jaringan PLN. Sistem dimanfaatkan sebagai backup untuk aliran listrik. Sistem akan bekerja secara otomatis ketika aliran listrik PLN terputus dengan memanfaatkan panel ATS (Automatic Transfer Switch). Pembangkit listrik tenaga surya sistem on grid ini cocok diterapkan di perumahan dengan memanfaatkan atap sebagai ruang untuk menyerap energi matahari. Sistem ini jika dipasang bersamaan dengan PLN akan mengurangi pengeluaran biaya listrik. Penerapan sistem atau prinsip kerja PLTS Grid Tie System ini dapat dijalankan dengan sistem kelistrikan PLN. Dalam sistem ini, jaringan listrik PLN berperan sebagai penyalur atau penghubung arus listrik yang berasal dari panel surya yang dialirkan pada beban. Dengan begitu pada siang hari, penggunaan listrik dapat memanfaatkan energi listrik dari sinar matahar dan pada malam hari karena tidak ada sinar matahari menyebabkan tidak ada produksi listrik dari solar panel, maka dapat tetap menggunakan arus listrik yang berasal dari PLN. Perencanaan dilakukan dengan pemilihan komponen PLTS, beban yang dibutuhkan 900Watt, lama waktu penyinaran efektif 10 jam/hari. kemudian melakukan perhitungan komponen PLTS, menentukan tata letak penempatan panel surya dan panel ATS (Automatic Transfer Switch) yang digunakan untuk membackup apabila jaringan listrik PLN terputus. Dari hasil pengukuran arus, tegangan dan daya di dalam rumah pada jam 07.00 sampai dengan 17.00 pada waktu cuaca cerah, yaitu sebelum Grid Tie Inverter dihubungkan ke jala-jala dihasilkan daya rata-rata, P=606,105Watt dan setelah Grid Tie dihubungkan ke jala-jala, P=292,63 Watt. Jadi penghematan daya beban di rumah yang dihasilkan sebesar 52 % dalam satu hari. Limited fossil energy in Indonesia has led to the development of new and renewable energy. Renewable energy is non-fossil energy that comes from nature. Utilization of solar energy can be done by building a Solar Power Plant (PLTS). PLTS planning uses an on-grid system, the system is still connected to the PLN network. The system is used as a backup for electricity. The system will work automatically when the flow of PLN electricity is cut off by utilizing an ATS (Automatic Transfer Switch) panel. This on-grid solar power plant system is suitable for residential use by utilizing the roof as a space to absorb solar energy. This system if installed together with PLN will reduce expenditure of electricity costs. The application of the system or the working principle of the PLTS Grid Tie System can be run with the PLN electrical system. In this system, the PLN electricity network acts as a distributor or connector for the electricity that comes from the solar panels that are flowed to the load. That way during the day, the use of electricity can take advantage of electrical energy from the sun and at night because there is no sunlight it causes no electricity production from solar panels, it can still use the electric current that comes from PLN. Planning is done by selecting the PLTS component, the load required is 900 Watt, the duration of effective irradiation is 10 hours / day. Then calculate the PLTS components, determine the layout of the placement of the solar panels and ATS (Automatic Transfer Switch) panels which are used to back up when the PLN electricity network is interrupted. From the results of measuring currents, voltages and power in the house at 07.00 to 17.00 when the weather is clear, that is, before the Grid Tie Inverter is connected to the grid, the average power is generated, P = 606.105Watt and after the Grid Tie is connected to the grid mesh, P = 292.63 Watts. So, the resulting load power savings at home is 52% in one day

Solar tracking devices are quite effective for collecting maximum solar radiations but for vastly spread solar energy collection plant, their usage is suppressed due to large cost involvement. The best alternative to this problem is adjustment of tilt angle at most appropriate position. In this study monthly optimum tilt angle have been identified for a solar power plant setup-able site Kalth (φ 30.85046˚, L 77.06153˚), situated at Himachal Pradesh, India. For diffuse radiation estimation, an isotropic model has been used. By considering the impracticality involved in monthly tilt angle adjustment, various annual adjustment models have been formulated for two, three and four annual adjustments. In order to estimate the increment in solar insolation by adopting these models, Performance Enhancement (PE) have been computed from the conventional method of setting the solar collector tilt equal to latitude angle. The results show that PE is maximum for monthly optimum tilt angles followed by M-4 which is a three annual adjustment model. Based on PE requirement, any of the proposed models can be selected for setting up solar energy collection plant at suggested site.

Introduction. An urgent scientific problem is to increase the efficiency of using solar energy in solar power plants (SES). The purpose of the article is to study methods for increasing the efficiency of solar power plants. Materials and Methods. Solar power plants based on modules with a two-sided working surface are considered. Most modern solar power plants use solar modules. The reflection of solar radiation from the earth’s surface provides an increase in the production of electrical energy by 20% compared with modules with a working surface on one side. It is possible to increase the efficiency of using solar energy by increasing the annual production of electric energy through the creation of equal conditions for the use of solar energy by the front and back surfaces of bilateral solar modules. Results. The article presents a solar power plant on a horizontal surface with a vertical arrangement of bilateral solar modules, a solar power station with a deviation of bilateral solar modules from a vertical position, and a solar power plant on the southern slope of the hill with an angle β of the slope to the horizon. The formulas for calculating the sizes of the solar energy reflectors in the meridian direction, the width of the solar energy reflectors, and the angle of inclination of the solar modules to the horizontal surface are given. The results of computer simulation of the parameters of a solar power plant operating in the vicinity of Luxor (Egypt) are presented. Discussion and Conclusion. It is shown that the power generation within the power range of 1 kW takes a peak value for vertically oriented two-sided solar modules with horizontal reflectors of sunlight at the installed capacity utilization factor of 0.45. At the same time, when the solar radiation becomes parallel to the plane of vertical solar modules, there is a decrease in the output of electricity. The proposed design allows equalizing and increasing the output of electricity during the maximum period of solar radiation. Vertically oriented modules are reliable and easy to use while saving space between modules.
