“…There were several configurations to arrange the heliostats in the solar field. Because of its lower blocking losses, a radial staggered layout is an optimum pattern for STP plants [5]. The graphical method for the no-blocking heliostat field was used to arrange the heliostats in a staggered radial field toward the north.…”

“…As a result, this sort of power plant can only be implemented in countries with a high potential for direct sunlight, known as the Sun Belt, as indicated in Figure 5. The minimum estimated direct solar radiation requirement for obtaining sufficient production is 1800 (kW/m 2 /year) [5].…”

“…Overall, it has a total annual average solar energy potential of 2.10 MWh/m 2 /year. It is located in North Africa, with latitudes ranging from 18.96 • N to 37.05 • N and longitudes ranging from 8.68 • W and 12 • E. The highest solar potential is in the southeast (Tamanrasset), as shown in Figure 1a, with a capacity of 2.38 MWh/m 2 /year [4,5]. Thus, the Algerian government intended to diversify its economy, reducing the country's reliance on fossil fuels in the electricity sector and satisfying the demand for energy, as shown in Figure 1b.…”

Generating electric power using solar thermal systems is effective, particularly for countries with high solar potential. In order to decide on a relevant location to implement the solar tower plant and develop the mathematical model of a no-blocking heliostat field, a meteorological assessment was discussed in this paper. In addition, a parametric study was examined to evaluate the effect of the designed parameters (heliostat size, heliostat height from the ground, tower height, receiver aperture, and the minimum radius) on the solar field’s performance. The preliminary solar field was then compared to the final design using the optimal design parameters. The obtained results showed that “Tamanrasset City” satisfied the necessary conditions for implementing a solar tower plant. According to preliminary solar field generation, no heliostat blocked its neighbor with a blocking efficiency of 100%. An analysis of its performance revealed that the optimized solar field would be capable of producing 15, 6571 MW, operating at an optical efficiency of 76.95%, and the enhancement rate of both efficiency and power output was 8.1%.

The main objective of photovoltaic system controller is to reduce the price of the kWh compared to traditional fuel-based electricity. Thus, the improvement of simple and low – cost controllers is a major challenge. Perturb and Observe (P&O) is the commonly used algorithm in order to ensure the power maximization of the photovoltaic system, due to its simplicity and effectiveness. However, on the main drawbacks of that algorithm is the fixed step size of perturbation, due to working environmental changes, which require dynamic tuning of the controller parameter. In order to overcome the cited disadvantage, a new Takagi - Sugeno variable step P&O is proposed. Based on the real-time measurements of the solar radiation and temperature, the proposed fuzzy system schedules the appropriate step size based on human expertise. A zero order Takagi – Sugeno with singleton output is proposed. The fuzzification were carried out using triangular and trapezoidal membership functions. The centroid defuzzification method based 25 If -Then rules are adopted. In order to verify the effectiveness of the improved P&O, three scenarios were used. The obtained results show the effectiveness of the proposed controller under shaded conditions and various temperatures.
