Geostationary Communication Satellite Solar Array Optimization Using Gravitation Search Algorithm

Abstract

The preliminary design of geostationary communication satellite solar array is presented in this work. Based on the power requirements, power margin requirements and performance requirements, the number of panels, strings and cells to be used on the solar array were defined. The main objective of this study was to optimize the power generated from the satellite solar array and the extraction of the parameters of a photovoltaic module, which is subject to the space environment and under a series of practical constraints, in order to extract the desired performance parameters for multiobjective functions, taking into account the solstice and equinox periods during temperature operation. A gravitational search algorithm based on the law of gravity and mass interactions was introduced. This algorithm has proved its effectiveness in optimizing system parameters in the literature. From the results obtained in this work, the total power of the optimized system was reduced by 181 W. The degradation and output power characteristics of the solar panels were calculated for different temperature values.

Review of modern applications of solar cells in communication systems

“…One of the most important results obtained in this research is the reduction of the total energy in the system 181 Watt, which is approximately (8.20% of the total energy), in addition to calculating the amount of energy produced in solar panels at different temperatures and calculating the degradation values. The paper also showed that the GSA (gravitational search algorithm) is close to the optimal design [7]. Y. Naga, S. Vamsi, and A. S. Raja (2021), This paper reviewed several optical wireless communications (OWC) receivers, which are considered as an alternative solution to solve the problem of wireless spectrum congestion, as different types of receivers can be used, such as the receiver that depends on Photodiode and the receiver that depends on solar cells in addition to the receiver that depends on the image sensor These systems work with the help of different sources such as visible light (VL), ultraviolet (UV) and infrared (IR).…”

“…The layers are lattice The anode, silicon and cathode, the anode is made of silver and the cathode is made of aluminum, while the silicon is based on a SiO2 insulating layer, it gives the ability to work at low voltage, high working frequency, low energy consumption and insensitivity to ionizing radiation [19]. S. Oukil and A. Boudjemai (2020), This paper presented a solar array design for a geosynchronous communications satellite depending on performance and power requirements. The number of panels, cells and strings used in the solar array was also determined.…”
