局部阴影条件下光伏阵列的优化设计。

随着光伏发电系统的结构及所处环境的复杂化(如光伏屋顶系统、光伏幕墙系统等)，尤其是局部阴影问题的出现，光伏阵列的输出特性受到很大影响。通过理论分析、计算机仿真及系统实验等方法，研究阴影分布的影响，提出在局部阴影条件下光伏阵列最大功率点的简化算法，总结阵列结构优化的原则，并在此基础上进一步考虑局部峰值及工作电压范围等因素的影响。提出适用性较广的光伏阵列优化设计方法，为光伏发电系统的工程设计提供有力的支持。

-Under optimized conditions of partial shading of the PV array design. With photovoltaic system structure and complexity of their environment (such as photovoltaic roof systems, photovoltaic curtain wall systems, etc.), especially the issue of partial shading, the output characteristics of the PV array has been greatly affected. By theoretical analysis, computer simulation and system test methods to study the effect shadows distribution algorithm is proposed to simplify the conditions under partial shade PV array maximum power point summary of the principles of an array of structural optimization and further consideration on the basis of local peaks and of the operating voltage range of other factors. Proposed broader applicability PV array optimization method, provide strong support for the engineering design of photovoltaic power generation system.
