Research on Energy Saving Optimization of Intermittent Generation Load Based on Super Capacitor

针对间歇性发电负载再生能量的二次利用问题,提出了一种基于超级电容的节能优化方法。首先,对不同间歇性发电负载的负载特性进行归纳研究,建立“类正弦曲线”理想化模型;其次,对超级电容器按功率-容量约束进行配置,大大提高性价比;最后,利用模糊逻辑中隶属函数的思想,提出了储能系统按比例功率分配的控制策略。经Matlab/Simulink仿真,其结果验证了所建模型及控制策略的有效性和可行性,实现了再生能量的有效回收及利用,对间歇性发电负载具有明显节能效果。
