摘　　要：建立了混合储能系统的数学模型,对系统性能的提升进行了定量分析。提出了一种无源式并联储能方案,并应用于独立光伏系统中,仿真和实验结果表明,在光伏系统的发电功率和负载功率脉动的情况下,蓄电池的充放电电流比较平滑。合理配置超级电容器组的容量,可以减少由于日照量变化所导致的蓄电池充放电小循环次数。对解决光伏等可再生能源系统中蓄电池储能的问题,具有现实意义。Mathematical model of the hybrid was set up to analyze the performance improvement quantificationally. A passive hybrid structure was put forward and utilized in a stand-alone system. Simulation and experiment show that the current of the battery is quite smooth under the condition of PV power and varying quickly load power, The small dis charge and recharge cycles due to irradiation variation can be reduced greatly through proper ultraeapaeitor bank configuration. Something valuable and practical can be attained from this paper to solve the energy storage problem in stand-alone PV system and other regeneration energy systems.
