【摘要】 独立光伏系统的设计是应在保证满足负载供电要求的前提下,综合环境条件、系统各部件性能的优化结果。其中光伏子系统功率及储能子系统容量设计是决定系统供电保障率、蓄电池寿命及造价的重要因素,应考虑光伏子系统功率与储能子系统容量的优化匹配。本文提出了光伏子系统功率范围及储能子系统容量设计范围,给出了一种设计计算蓄电池寿命的新方法,得到了独立光伏系统优化设计结果,并以实际的太阳辐射计算了两个系统的配置及蓄电池的寿命。更多还原

【Abstract】 This paper presents a novel method for calculating the lifetime of battery, PV array power range, battery capacity range and the optimum sizing of stand-alone photovoltaic systems. With two real solar radiation data designs for two stand-alone photovoltaic systems were calculated. The DOD is not the only one key factor to impact lifetime of battery. Comprehensive design should be put to the first position for design a stand-alone photovoltaic system because invest are quite different for different designs. For an optimum design the lowest solar radiation months should be considered and PV array should be a little larger especially in these uneven solar radiation areas.更多还原
