| Abstract: | By taking advantage of the photovoltaic (PV) power generation technology, the abundant solar energy resource in frigid plateau region can greatly improve the local energy infrastructure. However, the low efficiency of PV power plant has been existing as a widely publicized technical barrier. Specifically, the aging of PV modules, high surface temperature or partial shading may severely undermine the output of PV power plant. In this paper, take the example of the 4×2 PV arrays, based on the modeling and simulation with Matlab/Simulink software, the output characteristics of PV arrays are compared with respect to different structures under partial shading conditions. The results show that the RTCT structure outperforms all three others, with its maximum output power of PV array increased by 7.7% on average, such that the foundation for experiments is then formulated on enhancing PV arrays output power. Base on the experimental platform of PV arrays output power enhancement built in Lasa, the PV arrays output power enhancement technology is developed in terms of two methods, i.e., changing the topological structure of PV arrays and adding DC optimizers. The results show that both methods can increase PV arrays output power, which can provide solutions for optimization design and operation of PV power plant. |
