Abstract
Abstract: The output power of PV array not only depends on the irradiance intensity of the partial shadows, but also on the shadows shape. For the serious power loss under partial shadows of the traditional SP (Series-Parallel) and TCT (Total-Cross-Tied) structures, an optimized TCT structure is proposed. Output capacity comparison was made based on the three structures in five shadow modes under the circumstances of the severe shadows and uneven irradiation. By using Matlab/ Simulink software, the output performance of the three structures was simulated under different shadow shapes in symmetrical and asymmetric arrays. The results show that PV array with the optimized TCT structure works better in the different shadow conditions, which can provide selection references for the array structure in the construction of photovoltaic plants.
