摘要
介绍了一种改进的风/光互补发电系统优化设计的新方法,通过改变太阳电池方阵的倾角来适当改变各个月份太阳辐照量的大小及分布,使光伏发电和风力发电在各个月份的发电量更好地互相配合。通过比较各种光伏方阵倾角时各月发电量与平均值的均方根差,其最小值所对应的倾角即为最佳倾角。该方法可进一步优化结构,节省投资。
A novel method for optimizing design of the hybrid wind/photovoltaic generation system is introduced, which appropriately changes the amount and distribution of the solar radiation of every month by adjusting the declining angles of the solar cell matrix, and thus allows the 2 types of power generation, i.e. photovohaic and wind power generation, to complement each other better throughout the year. Comparing the root-mean-square- difference of the total electricity generated and the average amount of every month, the declining angle corresponding to the minimum root-mean-square-difference was obtained and can be considered as the optimal declining angle. The method can be used to further optimize the structure of the hybrid wind/photovoltaic generation system and to reduce cost.
