###### Abstract  
Enhancing the output power of stratospheric airship photovoltaic arrays during months with weak irradiance is crucial for extending the endurance of airships. Models for predicting the output power of photovoltaic arrays and the phenomenon of mismatch losses have been proposed. However, static reconstruction schemes to reduce or eliminate mismatch losses have not been studied. In this paper, an output power model for stratospheric airship arrays including the solar radiation and irradiance distribution is established. The characteristics of the irradiance distribution for the photovoltaic array (PV) are investigated through simulation. Furthermore, an innovative reverse combination configuration is developed and compared to the SP and TCT configurations in terms of performance, mismatch loss and fill factor. Finally, simulations are conducted for a full-day irradiance period of 4 days in a real wind field. The simulation results demonstrate that the proposed RC configuration significantly reduces mismatch losses and output power fluctuations, thereby enhancing the PV array's output power. This research provides interesting insights for the design of PV array topologies for stratospheric airships. photovoltaic array; stratospheric airship; mismatch loss; output power; static reconfiguration Article

Constrained by the current efficiency of solar cells [8] and the effective capacity of energy storage batteries, a larger-scale energy system is required to meet the high wind resistance demands of airships [9; 10], resulting in excessive volume and weight of the airship [11; 12]. Researchers aim to improve the power supply capacity of the airship's energy system by optimizing the utilization of PV arrays and energy management to meet the energy balance requirements. Enhancement of the PV array's power supply capacity can be effectively achieved through layout optimization and thermal control. [PERSON] et al. [13] conducted a multi-objective optimization design for the thermal insulation and heat dissipation layers of photovoltaic arrays, resulting in an increase in the power output per unit area from 88.5 W to 95.4 W. [PERSON] et al. [14] proposed a genetic algorithm-based model for optimizing the layout of PV arrays, resulting in the identification of the optimal arrangement for PV arrays under four typical operational conditions. [PERSON] [15] proposed a multidisciplinary optimization method for HAA based on genetic algorithms, achieving an optimal layout of five deployment positions for PV arrays. [PERSON] et al. [16] analyzed the sensitivity of power output to the rotational angle and installation angle of PV arrays during cruising, and indicated that the optimal installation angle for PV arrays should be controlled within \(\pm\)20\({}^{\circ}\). To further enhance the energy acquisition during the operation of airships, an increasing amount of research is focusing on the design of flight strategies and attitude planning. [PERSON] [17] analyzed the sensitivity of the airship's attitude angles to PV arrays and found that the yaw angle has the greatest impact. [PERSON] et al. [18] proposed an optimal yaw angle strategy in quasi-zero wind fields, aiming to maximize the output power of the PV array. The result demonstrates that the optimal yaw angle varies with the working dates and latitude and is primarily concentrated at 0\({}^{\circ}\) and 180\({}^{\circ}\). [PERSON] [19] devised an integrated attitude manipulation strategy encompassing roll, pitch, and yaw control, resulting in a substantial enhancement of energy production and wind resistance capabilities of airships. [PERSON] [20] proposed an airship energy management scheme based on a position energy storage strategy. This approach optimized the allocation of energy throughout the day, thereby enhancing the airship's endurance. Furthermore, researchers proposed strategies for controlling the angle of irradiation incidence to enhance the PV arrays' output power.
