| 摘 要： | 为了考察超级电容微网储能性能,以典型超级电容实际产品为对象,针对恒电压、恒电流以及恒功率3种充电模式,研究充电时间及储能效率问题.提出了各种充电模式的数值计算方法,并利用严格的数学推导讨论了不同充电模式的效率问题.同时通过一个独立PV/EDLC系统验证了计算的准确性.最后研究分析了不同充电模式的充电速度与能量损失的权衡问题.研究结果表明：与传统的恒电压和恒电流充电方式相比,恒定功率充电方式更适用于微网系统.混合充电方式在实际应用中会更高效节能,但需根据实际具体要求合理处理不同充电模式的组合比例.

| Abstract: | In order to review storage performance of the electric double layer capacitor （EDLC） in microgrid applications, charging time and storage efficiency issues are mainly studied aiming at three different charging modes, including the constant voltage charging mode （CVCM）, the constant current charging mode （CCCM） and the constant power charging mode （CPCM）, based on the practical EDLC product. Numerical calculation methods are presented for different charging modes, and the charging efficiency is also reviewed with strict mathematical deductions, which is validated to be accurate enough and applicable through a simple case with the PV/EDLC system illustration. Finally, trade-off problems between charging time and energy loss are also studied. Research results show that the CPCM is more suitable for microgrid networks compared with the traditional constant-voltage and constant-current charging modes. The hybrid charging method is recommended to save energy and keep high efficiency relatively at the same time. However, how to manage the combination percentage of different charging modes in a reasonable way should be dealt with according to the practical requirements. |
