【摘要】：維持直流母線電壓穩(wěn)定是保證直流微電網(wǎng)穩(wěn)定運(yùn)行的核心,亟待展開深入研究。該文首先將直流微電網(wǎng)內(nèi)母線電壓波動(DC bus voltage fluctuations,DC BVF)按時(shí)間尺度、頻率特性和產(chǎn)生機(jī)理分為擾動型波動和振蕩型波動兩種;然后,對擾動型DC BVF和振蕩型DC BVF現(xiàn)有的抑制方法以及基于分層控制體系的能量管理系統(tǒng)進(jìn)行了綜述研究,重點(diǎn)就雙向AC/DC變換器負(fù)載電流和功率前饋控制方法的DC BVF抑制方法、電網(wǎng)不平衡及諧波情況下的AC/DC變換器直流側(cè)功率諧波抑制方法、基于母線電壓調(diào)節(jié)器(voltage bus conditioner,VBC)的DC BVF抑制方法以及直流微電網(wǎng)多源協(xié)調(diào)和能量管理控制方法及其存在的問題進(jìn)行了評述;最后,結(jié)合文中的DC BVF分類方法,分別對擾動型波動和振蕩型波動抑制方法的前景進(jìn)行了展望。
[Abstract]:Maintaining the voltage stability of DC bus is the core to ensure the stable operation of DC microgrid, and it is urgent to carry out further research. In this paper, the bus voltage fluctuation (DC bus voltage fluctuations,DC BVF in DC microgrid is divided into disturbance fluctuation and oscillatory fluctuation according to time scale, frequency characteristics and generation mechanism. Then, the existing suppression methods of disturbance DC BVF and oscillatory DC BVF and the energy management system based on hierarchical control system are reviewed and studied, with emphasis on the DC BVF suppression method of load current and power feedforward control method of bidirectional AC/DC converter, the DC side power harmonic suppression method of AC/DC converter under the condition of power grid imbalance and harmonics, and the (voltage bus conditioner, based bus voltage regulator. The DC BVF suppression method of VBC), the multi-source coordination and energy management control methods of DC microgrid and their existing problems are reviewed. Finally, combined with the DC BVF classification method in this paper, the prospect of disturbance wave and oscillatory wave suppression methods is prospected respectively.
