    摘 要:傳統(tǒng)獨(dú)立光伏發(fā)電系統(tǒng)以蓄電池作為儲能裝置,難以滿足負(fù)載動態(tài)響應(yīng)性能要求。基于超級電容器,研究了獨(dú)立光伏直流發(fā)電系統(tǒng)的相關(guān)技術(shù),提出新型的能量管理模式,根據(jù)外界環(huán)境變化,系統(tǒng)前級電路在MPPT 模式與恒壓模式中切換,后級電路在充電模式、放電模式與待機(jī)模式中切換。仿真結(jié)果表明,新型能量管理模式與控制策略具有良好的控制效果,系統(tǒng)可以高效優(yōu)良地工作在現(xiàn)實(shí)環(huán)境中。

    Abstract: The traditional independent photovoltaic power generation system uses the storage battery as the energy storage device, which is difficult to meet the dynamic response performance requirements of the load. Therefore, it is a very necessary research topic to study the technology related to super-capacitor independent photovoltaic power generation system, explore the management and application mode of new photovoltaic energy system. According to changes in the external environment, the pre-stage circuit of the system switches between MPPT mode and constant voltage mode, and the post-stage circuit switches between charge modes, discharge mode and standby mode. Finally, it is found through simulation that the new energy management mode and control strategy have good control effects, and the system can work in the real environment efficiently and effectively.
    Key words: photovoltaic power generation; MPPT; super-capacitor; energy management
