Purpose This paper aims to study the Lut desert, also known as the Dasht–e–Lut, starting with a summary of its location as a large salt desert in southeastern Kerman, Iran, as well as its climate, being one of the world’s driest places. Next, a statistical analysis is performed based on a reasonable minimum level of 10 per cent. The computation of electric energy produced by sunlight in the studied region is, then, provided using a number of high-efficiency and suitable solar cells. Finally, the authors will compare the production of electrical energy to the consumption energy in Iran and Kerman province. Design/methodology/approach According to calculations of the present study and the analyses of the tables and charts provided, the use of solar energy and the amount of energy used in different areas was discussed. Lut desert in Iran is one of the touristic attractions of Kerman province: while only a very small area of this desert known as the Kalut is of interest to tourists, the vast remaining area of this desert is currently left without use. Lut and its surrounding towns and villages are not suitable for agricultural due to the lack of water in the region, and relatively poor people live within the area. The findings of this study showed that throughout the region, there is a very high potential for energy supply of Kerman and Iran. Findings The practical use of Lut desert potential in the production of electric energy from solar energy, besides its significant role in cost reductions, can also positively affect the living standards of local residents as well as job and income creation for the country. Efficient use of only 10 per cent of the area of Lut desert, via using its solar energy, can produce a considerable amount of energy for the region and for the country in large. Although the present study only investigated the solar energy of the region, it also has a high potential in wind energy and geothermal optimum use. The research team will, hence, continue its work on calculating the amount of energy generated from all types of renewable energy in this area. This paper showed that application of solar cells in this region is appropriate for providing a magnificent amount of electric-energy requirements of Kerman province and of Iran. Originality/value In recent years, Iran’s nuclear, oil and natural-gas industries have been the subject of intensifying sanctions from certain international communities. Now, the country wants to develop a sector in which it has more leeway, i.e. the renewable energy; wind and solar energies are always available, and no one can put sanctions on them. Also, to provide household electricity in remote areas (which are not connected to the mains electricity grid), energy storage is required for use of renewable energy. Usually, however, renewable energy is derived from the main electricity grid, and this means that as the mains electricity grid is organized so as to produce the exact amount of energy being consumed at that particular moment, the energy storage is mostly not applied. Energy production on the mains electricity grid is always set up as a combination of renewable-energy plants, as well as other power plants (e.g. the fossil-fuel power plants and nuclear power). This combination, nevertheless, is essential for this type of energy supply (i.e. the wind turbines, solar power plants, etc).

In the presented work, the possibility of using photovoltaic silicon panels with a double-sided arrangement of solar cells on the front and back sides is presented. With a lack of space for placing solar panels, these types of modules can significantly increase the generation of electrical energy. Equipping photovoltaic systems with rechargeable batteries contributes to a more rational consumption of electrical energy, while energy storage systems significantly increase the efficiency of solar generating systems. The proposed designs are intended to increase the power characteristics of solar energy converters in the winter months, in the presence of snow or when using reflective surfaces on road surfaces. The results of the experimental studies have shown a significant efficiency of the proposed designs, as well as an increase in the total generation of electrical energy. With the development of the global technical potential and a significant increase in the production of power plants for solar energy, a new opportunity has emerged to use combined solar plants for photovoltaic conversion of the flux of incident solar radiation. At the Department of Renewable Energy Sources and Electrical Systems and Networks at Sevastopol State University, at the site of the Institute of Nuclear Energy and Industry, a photovoltaic installation was developed and studied, consisting of two side silicon solar cells and energy storage systems. The article presents the results of experimental and theoretical studies, presents diagrams, drawings and graphs of various characteristics of the FSM-110D photovoltaic panel and storage batteries. The research results show the increased efficiency of the proposed installation, as well as a good possibility of using the presented photovoltaic systems to provide them with autonomous and individual consumers living in the Crimean region and the city of Sevastopol.

A detailed substantiation of the use of electric energy storage devices in the presence of generators on renewable energy sources in the power supply system is given. The dependence of the storage parameters on the composition and priority of generation in the system is investigated. The solution of the problem of determining the parameters of electricity storage devices by means of purposeful simulation of generation parameters is considered. The results of the choice of power and capacity of the energy storage using technical and economic indicators are shown. Optimal parameters of electric energy storage devices as one of the most important means of ensuring the activity of isolated power supply systems together with selection of generating devices are determined. The results of calculations of capacity of renewable energy sources in isolated power supply systems in combination with classical energy sources are given. The necessity of using the principle of activity of the distribution electric network and the possibility of its realization is demonstrated. The optimal storage capacity as a function of the share of renewable generation, the non-integrated energy produced by renewable sources and the total storage capacity are plotted for several isolated systems. The main points of the used model of the power supply system of isolated networks are given. In the studied isolated power supply systems, wind power plants and solar power plants, which have significant unpredictability of generation, are used as generation based on renewable energy sources. The problem of undersupply of electricity to the grid by stepwise increase of generation is analysed. The results of the multi-step selection of power and energy consumption of electricity storage are determined by technical criteria.

Abstract Lack of investment in the electricity sector has created a huge bottleneck in the continuous flow of energy in the market, and this will create many problems for the sustainable growth and development of modern society. The main reason for this lack of investment is the investment risk in the electricity sector. One way to reduce portfolio risk is to diversify it. This study applies the concept of portfolio optimization to demonstrate the potential for greater use of renewable energy, which reduces the risk of investing in the electricity sector. Besides, it shows that investing in renewable energies can offset the risk associated with the total input costs. These costs stem from the volatility of associated prices, including fossil fuel, capital costs, maintenance, operation and environmental costs. This case study shows that Iran can theoretically supply ~33% of its electricity demand from renewable energy sources compared to its current 15% share. This case study confirms this finding and predicts that Iran, while reducing the risk of investing in electricity supply, can achieve a renewable energy supply of ~9% with an average increase in supply costs. Sensitivity analysis further shows that with a 10% change in input cost factors, the percentage of renewable energy supply is only partially affected, but basket costs change according to the scenario of 5–32%. Finally, suggestions are made that minimize risk rather than cost, which will bring about an increase in renewable energy supply.

A nuclear power plant is one of the power sources that shares a large portion of base-load. However, as the proportion of renewable energy increases, nuclear power plants will be required to generate power more flexibly due to the intermittency of the renewable energy sources. This paper reviews a layout thermally integrating the liquid air energy storage system with a nuclear power plant. To evaluate the performance realistically while optimizing the layout, operating nuclear power plant conditions are used. After revisiting the analysis, the optimized performance of the proposed system is predicted to achieve 59.96% of the round-trip efficiency. However, it is further shown that external environmental conditions could deteriorate the performance. For the design of liquid air energy storage-nuclear power plant integrated systems, both the steam properties of the linked plants and external factors should be considered.

Energy use always increases, especially fossil energy. Through the National Energy Policy, the government continues to strive to increase the role of new and renewable energy sources so as to reduce dependence on fossil energy. Solar power generation is a type of renewable energy generator that capable to convert solar energy to electric energy. The main components of solar power generatios are batteries, solar panels, charger controllers, and inverters.  Solar power generations technology itself is always being developed, such as automatic monitoring and sun tracking systems designed to improve system performance. One of the applications of solar power generations is in the household sector. In this sector consumes 49% of the national electricity energy in 2018. This type of generator is categorized as a roof solar power generations. Based on existing data, there were 1400  roof solar power generations users in September 2019. The development of solar energy utilization for the household sector is very appropriate because it can help achieve renewable energy about 23% in 2025 and 31% in 2050 in the national energy mix.
