局部阴影条件下光伏阵列输出特性的研究 总被引:1,自引:0,他引:1
当光伏阵列处于阴影情况下时,输出的I-V曲线呈阶梯状,相应的P-V曲线含有多个局域峰值。通过理论分析、Matlab仿真以及实验测试,研究阴影分布对光伏模组输出特性的影响。并以工程用光伏电池模型为基础,用Matlab语言建立了一个简单实用的光伏阵列辅助设计软件,利用该软件对光伏阵列在不同光照、温度、遮挡模式以及阵列结构下进行仿真研究,深入分析了光伏阵列在局部阴影下的I-V和P-V特性,给出全局最大功率点位置随遮挡模式变化的定性结论,为局部阴影下光伏阵列特性和最大功率点跟踪算法的研究提供了有力的支持。 相似文献

Rate design serves objectives of cost recovery, market animation, and customer incentives. Yet in the quest to find the ‘perfect equitable rate,’ many rate designers and pilots overlook the diversity of consumer attitudes. AMI enables not only interval monitoring and controls, it allows alternative pricing plans, payment options, device adoption, and generation mixes reflecting individual priorities. Connecting consumer attitudes with a portfolio approach helps regulators and utilities achieve specific goals while improving satisfaction and engagement. 相似文献

This analysis explores the impact that the evolution of retail electricity tariffs can have on the deployment of solar photovoltaics. It suggests that ignoring the evolution of tariffs resulted in up to a 36% higher prediction of the capacity of distributed PV in 2050, compared to scenarios that represented tariff evolution. Critically, the evolution of tariffs had a negligible impact on the total generation from PV—both utility-scale and distributed—in the scenarios that were examined. 相似文献
