摘要
提高太阳能路灯储能系统的寿命和性价比是光伏应用中的一个重要问题。分析了太阳能路灯储能系统的出力规律。根据出力规律,提出应采用多种不同层次的储能元件,按照循环寿命和使用频率相匹配的原则来设计混合储能系统,才能提高太阳能路灯储能系统的寿命和性价比。理论分析和实验证明该设计策略可以有效延长太阳能路灯储能系统的寿命,并且具有经济可行性。
How to improve life and performance-price ratio of energy storage system of solar road lamp is a key problem in photovoltaic applications. The cycle characteristics of energy storage system of solar road lamp were discussed. Based on the cycle characteristics, a design strategy was introduced that different kinds of storage elements were adapted to design hybrid energy storage system according to the principle of match of cycle life and usage frequency. Theoretical analysis and experiments show that the strategy can extend the life of energy storage system of solar road lamp and is economical and feasible.
