ABSTRACT
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.

Systemy fotowoltaiczne (PV) i skoncentrowanej energii słonecznej (CSP) to obecne światowe trendy w wykorzystywaniu energii słonecznej do wytwarzania energii elektrycznej. Energia słoneczna wytwarzana z ogniw fotowoltaicznych (PV) jest uważana za główną powszechnie stosowaną technologię ze względu na jej niski koszt kapitałowy, jednak stosunkowo niska wydajność ogniw fotowoltaicznych zwróciła uwagę na rozwój i badania nad zastosowaniami silników cieplnych wykorzystujących skoncentrowaną energię słoneczną. W warunkach posiadanego potencjału słonecznego Sudanu wydajność skoncentrowanej energii słonecznej jest większa niż PV. Dlatego niniejsze badanie zostało przeprowadzone w celu zwrócenia uwagi na wykorzystanie CSP w Sudanie, ponieważ udział CSP jest nieznaczny w porównaniu z PV, pomimo przydatności zastosowań CSP do gorącego klimatu Sudanu i wysokich zasobów energii słonecznej. W pracy przedstawiono projekt modelu parabolicznych kolektorów rynnowych (PTC) o mocy 1 MW z wykorzystaniem cyklu Rankine’a z magazynowaniem energii cieplnej (TES) w Sudanie, przyjmując wartości referencyjne elektrowni Gurgaon PTC w Indiach. Zaproponowano projekt elektrowni słonecznej o mocy 1 MW wykorzystującej paraboliczne kolektory rynnowe (PTC) i magazynowanie energii cieplnej. Symulacja została przeprowadzona dla miejsca zlokalizowanego koło Chartumu, o rocznym bezpośrednim napromieniowaniu normalnym (DNI) 1915 kWh/m2.
Wyniki pokazały, że elektrownia może wyprodukować od prawie 0,6 do 1 MWh w ciągu roku i około 0,9 MWh, przy wykorzystaniu magazynowanie energii cieplnej ze średnią sprawnością cieplną 24%. Te wyniki elektrowni PTC zachęcają do dalszych badań i rozwoju technologii CSP do wytwarzania energii elektrycznej w Sudanie.
