Abstrakt

The article analyzes and evaluates the development of renewable energy from the standpoint of state regulation and incentives. It is noted that the global production of renewable electricity has increased by 15% over the last year. The periods of introduction of the “green tariff” as an economic stimulus for the development of solar energy, which became the starting point for the development of alternative generation in different countries, are analyzed. The role of institutional factors in the development of renewable energy, such as the free issuance of licenses for electricity generation, stimulating the creation of specialized research areas, technology development and production of relevant equipment, was observed. The necessity of taking into account the regional peculiarity in the state stimulation of the development of renewable energy is proved. The economic efficiency of the state regulation of alternative energy in time measurement per conditional unit of alternative renewable energy stations was calculated, taking the coefficient of proportionality into account. Therefore, the calculation indicates the high effectiveness of government policy in regulating energy in terms of only short-term lag (α = 1.3) and the number of stations 80 percent of full saturation relative to the basic needs of energy consumption. A separate further stage in the development of renewable energy without the introduction and expansion of the “green tariff” has been identified. This approach was introduced in Poland, which ensured the country not only the inflow of foreign investment, but also the formation of free competition among investors.

Solar photovoltaic (PV) and concentrated solar power (CSP) systems are the present worldwide trends in utilizing solar energy for electricity generation. Solar energy produced from photovoltaic cells (PV) is considered the main common technology used due to its low capital cost; however, the relatively low efficiency of PV cells has spotlighted development and research on thermal engine applications using concentrated solar power. The efficiency of concentrated solar power is greater than that of PV and considering the solar potential for Sudan. Therefore, this study has been performed in an attempt to draw attention to the utilization of CSP in Sudan since the share of CSP is insignificant in comparison with PV, besides the suitability of CSP applications to Sudan’s hot climate and the high solar energy resource, the study presents a design model of 1 MW parabolic trough collectors (PTC) using the Rankine cycle with thermal energy storage (TES) in Sudan, by adopting reference values of the Gurgaon PTC power plant in India. The design of a 1 MW Concentrated Solar thermal power plant using parabolic trough collectors (PTC) and thermal energy storage is proposed. The simulation was performed for a site receiving an annual direct normal irradiance (DNI) of 1915 kWh/m2, near Khartoum. The results showed that the plant can produce between nearly 0.6 to 1 MWh during the year, and around 0.9 MWh when it encompasses thermal energy storage with an average thermal efficiency of 24%. These results of the PTC Power plant encourage further investigation and the development of CSP technologies for electricity generation in Sudan.

Abstrakt

The construction of large solar parks requires dedicated landscaping methods. Solar parks — colloquially called photovoltaic farms or solar power plants — require landscape conservation measures to be implemented in the areas adjacent to these projects. This is an extremely important issue for sustainable development and the protection of cultural assets and identities, including the rural landscape. The aim of this work is to present the possibilities of landscape protection using the example of the planned solar park in the municipality of Pobiedziska in the Greater Poland Voivodeship. The studies use case studies, qualitative and quantitative analyses and in situ tests. The studies covered the planned investment area of 160 ha and the adjacent areas. The project proposals for landscape protection applied in this case — ‘green protection walls’ — were presented. The measures presented make it possible to preserve open-air landscapes in agricultural and rural areas from the point of view of sustainable development and the protection of cultural assets, and their formula, adapted to the landscape, can be applied to a large extent and can be dedicated to the local conditions in rural areas.

Abstrakt

W artykule przedstawiono obliczenia i studium wykonalności wdrożenia elektrowni słonecznych dla stanów New Jersey, Nowy Meksyk i Michigan. Pod uwagę wzięto średni koszt energii sieciowej, średnie miesięczne zużycie kWh w gospodarstwie domowym oraz średni koszt systemu o mocy 6 kW z zastosowaną 26% federalną ulgą podatkową. Podejście przedstawione w tym artykule proponuje uwzględnienie zmian wartości pieniądza, taryf i okresu eksploatacji elektrowni słonecznej.
Z przeprowadzonych badań wynika, że budowa SPP w USA może być opłacalna w warunkach stałego wzrostu cen energii elektrycznej wytwarzanej w tradycyjnych źródłach energii. Jednak przy stabilności cen energii elektrycznej wykorzystanie energii słonecznej nie jest najbardziej opłacalną inwestycją.
Udowodniono, że istnieje potrzeba skupienia się na badaniach nad najnowszymi technologiami magazynowania i wytwarzania energii, aby w przyszłości ograniczyć wpływ niestabilności produkcji energii odnawialnej na stabilność sieci elektroenergetycznych. Dalszy rozwój SPP może pomóc w zwiększeniu ich dostępności i konkurencyjności, co przyczyni się do stworzenia zrównoważonej i zielonej infrastruktury energetycznej. Rozwój technologii w tym obszarze doprowadzi także do spadku cen instalacji i wzrostu wydajności paneli.
Głównym ograniczeniem elektrowni słonecznych jest konieczność posiadania dużej powierzchni pod montaż paneli, aby osiągnąć poziom przemysłowej produkcji energii elektrycznej. Dlatego obecnie scentralizowana produkcja energii elektrycznej za pomocą słońca jest możliwa tylko na obszarach nienadających się do życia i działalności gospodarczej.
