摘要/Abstract

摘要： 交直流混合微电网的直流母线电压的稳定控制对整个交直流混合微电网系统十分重要。针对交直流混合微电网中直流母线电压控制方式,提出一种实用、高效的交直流混合微电网直流母线电压自主偏差控制方法。在并网模式下,采用具有空闲模式下的直流母线电压下垂稳定控制方法,通过AC/DC变换器实现直流母线电压的稳定控制,避免了AC/DC变换器的频繁充放电操作;离网模式下,直流母线电压的稳定控制由接储能侧的DC/DC变换器控制。为了保证系统离网模式下可靠运行,直流母线侧可以接多路DC/DC储能类蓄电池,通过自主稳定控制既提高了分布式能源的利用率,又提高了空闲模式下电力电子设备的使用寿命。经试验验证,该方法具有很好的控制效果,为交直流混合微电网的发展提供了技术基础支撑。

Abstract: DC bus voltage stability control is very important for hybrid AC/DC micro-grid. A practical and efficient control method is proposed for DC bus voltage deviation stability control autonomy of hybrid AC/DC micro-grid. In grid-connected mode, the droop control method of DC bus voltage under idle mode is used to control the DC bus voltage stability through AC-DC inverter, which can avoid frequent charge-discharge. In islanding mode, the DC bus voltage is controlled by DC-DC converter. For reliability of system in islanding mode, the DC bus can connect multipath DC-DC stored batteries. The distributed energy utilization ratio is improved through autonomous stability control, and the service life of electronic devices are increased under idle mode. Experimental tests prove that the proposed method has good control efficiency and can provide a good technical support for the rapid development of hybrid AC/DC micro-grid.

Key words: hybrid AC/DC micro-grid, DC bus voltage, deviation control autonomy
