Photovoltaic solar energy is still in its infancy in Burkina Faso, despite the country’s high solar potential. The electricity grid is experiencing an increase in demand for energy, creating a shortfall in supply. The Zagtouli photovoltaic solar power plant in Burkina Faso is the first milestone in the development of renewable photovoltaic energy, with a rated output of 33.6 Megawatts peak, to strengthen the electricity grid by reducing hydrocarbon consumption. The aim of this work is to evaluate the performance of the plant by proposing a performance score for the Zagtouli plant, which should provide a basis for assessing the performance of a power plant. To meet the objectives, we collected data for three consecutive years of production, from 2019 to 2021. From this data, we used the method based on the calculation of the performance indicators specified by the International Energy Agency (IEA) and described in the standardised norms IEC (International Electrotechnical Commission) CEI61724, and we also carried out a performance classification using the K-Means method. It is clear that with the results obtained for the PR performance index (over 70%), the installation can be classified as one of the best-performing systems. It also emerges that various losses (temperatures on the panels, cabling, partial shading, spectral losses, dirt, and unexpected inverter failures) have a negative impact on the installation’s energy production.

Estimating the Input Power of a Power Plant Using the Efficiency of the Inverter

引用

Smart Grid and Renewable Energy 2024年第3期15卷 99-106页

The study focuses on estimating the input power of a power plant from available data, using the theoretical inverter efficiency as the key parameter. The paper addresses the problem of missing data in power generation systems and proposes an approach based on the efficiency formula widely documented in the literature. In the absence of input data, this method makes it possible to estimate the plant’s input power using data extracted from the site, in particular that provided by the Ministry of the Environment. The importance of this study lies in the need to accurately determine the input power in order to assess the overall performance of the energy system.

Background and Objectives: Dengue is an arbovirosis caused by the dengue virus with 04 serotypes. The aim of the study was to characterise the four serotypes (DENV-1, DENV-2, DENV-3 and DENV-4) of the dengue virus circulating in Ouagadougou, Burkina Faso. Methods: This was a descriptive analytical study that included 2833 patients and was carried out from January 2021 to December 2022. Rapid diagnosis of dengue was performed using the “Dengue Duo (AgNS1/IgM/IgG)” kit (SD Bioline, Korea). Viral RNA was extracted using the QIAGEN RNA Rneasy Plus Mini Kit (Quiagen, Germany) and virus serotypes were identified using the DENGUE Real-TM Genotype PCR kit (Sacace biotechnologies, Italy). Platelet counts were also performed using the XN-1500 Sysmex. Results: The prevalence of acute infections (NS1Ag positive) by TDR was 5.7% (162/2833), with the peak of dengue virus infection occurring between October and November. On the other hand, the AgNS1+ samples tested by RT-PCR were 53.7% positive for dengue virus;this shows the extent of probable cross-reactions with rapid diagnostic tests and false positives. Serotype 1 accounted for 52.6%, 28.4% had serotype 3, 16.8% had serotype 2 and 2.1% had serotype 4. We found cases of co-infection with DENV-1 and DENV-2 in two patients, co-infection with DENV-1 and DENV-3 in three patients, co-infection with DENV-1 and DENV-4 in one patient, co-infection with DENV-3 and DENV-4 in one patient and co-infection with three serotypes, DENV-1, DENV-2 and DENV-3 in one patient. Conclusion: The study showed that all four serotypes of the dengue virus were circulating in Ouagadougou. Serotype 1 was predominant.
