混合储能在风光互补发电系统中的能量管理与控制策略

储能技术在风光互补发电技术中的应用使得风光互补发电技术得到了进一步完善，各个部分的控制更加合理、有效，系统更加稳定、安全，并且使用效率及寿命得到了提高。通过仿真验证了一种蓄电池与超级电容混合储能结构，在这种结构中通过控制DC/DC变换器将蓄电池的高能量密度及超级电容的高功率密度的特点相结合，并且运用滑动滤波器进行二者的能量分配，同时通过DC/DC变换器达到对各储能部分实时控制的目的，从而提高了混合储能系统的灵活性与实用性。

Power Management and Control Strategy of a Hybrid Energy Storage in Wind-Solar Hybrid Generation System

The application of energy storage technology ensures the stability and security of the system and the improvement of the efficiency and life span.By integrating the advantage of storage battery in high energy density with that of super capacitor in high power density, a kind of mixed energy-storage structure with storage battery and super capacitor is proved in this paper. The sliding filter is applied to energy distribution, and the DC/DC changer is used to control those energy storage models in a real-time way, so as to improve the flexibility and widen the application fields of the whole system.
