摘要

针对独立光储系统应用在太阳能无人机、无人飞艇中时存在的光伏组件间光照不均衡、大规模成组的储能电池特性不一致及安全性等问题,提出了一种基于光储模块的新型光伏发电系统方案。在该系统中,光伏与储能电池分别经过适当规模成组后,由功率电路组合为一个可控的光储模块,以实现光伏与储能的优势互补并提高整体性能。光伏发电系统由若干光储模块串并联构成,通过它们之间的协调控制实现光伏电池、储能电池配置容量的充分利用。在对这个系统的拓扑结构、工作原理、控制策略进行充分理论分析的基础上,通过仿真及实验验证了系统的可行性和有效性。
        A new photovoltaic power generation system scheme based on photovoltaic-storage module is proposed to solve the problems of uneven illumination between photovoltaic components,inconsistent characteristics and safety of large-scale energy storage cells when the independent storage system is used in solar drones and unmanned airships.In this system,after the photovoltaic and energy storage cells are grouped on the appropriate scale,the power circuit is combined into a controllable photovoltaic-storage module to achieve the complementarity of the advantages of photovoltaic and energy storage and improve the overall performance.The photovoltaic power generation system consists of several photovoltaic-storage modules in parallel.Through the coordination and control between them,the photovoltaic cell and energy storage cell configuration capacity are fully utilized.Based on the theoretical analysis of the topology,working principle and control strategy of the system,the feasibility and effectiveness of the system are verified by simulation and experiment.
