“…This study focuses on Tamanrasset, a city in southern Algeria with an ideal location for utilizing solar energy and its associated technologies. The city's geographical coordinates are listed in [12]. The average monthly daily solar radiation data, measured in MJ/m 2 /day, were obtained from various national and international databases, including the Solar Atlas of Algeria [12,27,28], the Photovoltaic GIS, and Metronome, which is a commercial data source.…”

This work investigates integrating vegetation into solar chimney power plants (SCPPs) using numerical simulations of an SCPP prototype in Spain. A 2D axisymmetric computational fluid dynamics model with radiation heat transfer was employed to evaluate the impact of vegetation beneath the solar collector roof on system performance. Different SCPP configurations were analyzed: a standard design, one with a secondary collector roof, and another with secondary and tertiary collector roofs. Results indicate the secondary and tertiary roof configuration exhibited the highest annual electricity generation capacity of 34-80 kW. While introducing vegetation under the collector appears feasible, it is likely to reduce the overall energy output. In summary, simulations suggest that vegetation influences SCPP operation, decreasing power production, while incorporating multiple collector roofs enhances the generation capacity.

The solar chimney is one of the uninvestigated areas in the possible selection in the field of renewable solar energy utilization. CFD can be demonstrated as a useful tool of figure confidence in the design and employment of a solar chimney. A realistic numerical model for a solar-based updraft power plant for power generation was established through this research work. Iraqi weather in Kirkuk, northern Iraq was considered for this case study. A three-dimensional (3D) simulation of the main geometric dimensions of the Spanish, Manzanares model integrated with a real turbine was performed using computational fluid dynamics (CFD). The turbulent model of RNG k-e, the nongrey discrete coordinate (DO) radiation model, and the solar raytracing algorithm were used. It was observed that the air velocity below the turbine was graded according to the seasons of the year and was at its maximum in July with 18.28 m/s due to the high ambient temperature, and the lowest value was recorded in January with 8.64 m/s. The overall average daily and monthly energy production values for the Kirkuk system were higher than those of the Kubang system, with values of 310 kWh/day and 9314 kWh/month, respectively, for the Kirkuk system, and 246 kWh/day and 7398 kWh/month, respectively, for the Kubang system. The simulation results showed that the electricity generation from the Kirkuk city power plant varied seasonally to be at its maximum value of 14,424 kWh/month in July. This research work will help to determine the possibility of producing electricity in this Kirkuk city, which would then contribute in a great way to reduce the cash spent on electricity.

This work evaluates the impact of integrating a hybrid solar chimney power plant (HSCPPS) into a medium voltage distribution grid in the Safawi area, Jordan. The HSCPPS can operate as a traditional solar chimney power plant system during the day and as a cooling tower during the night, achieving continuous system utilization. Real data from the distribution grid and CYME software are used to monitor the impact of integrating the HSCPPS to the grid over a 24-hour duration. The impact of the integration step on the performance parameters of the grid corresponding to voltage profile, losses, power factor (PF), and voltage step are investigated. For each of these parameters, a comparison between the grid performance with and without the HSCPPS is carried out and demonstrated. The results show a maximum reduction of voltage deviation from the nominal value by around 0.9%, a maximum reduction in the losses by approximately 0.33%, and a reduction in the PF from 0.83 to 0.74 as the HSCPPS is set to supply only active power (unity PF). In addition, the voltage step test is carried out according to International Electrotechnical Commission 61000-3. The results show that there is a safe margin, and the voltage step limits did not exceed 3% of the nominal voltage.
