摘　　要：为了解决能源短缺问题,可再生能源发展及应用成为研究热点。其中,交直流混合微电网是实现能源供需平衡及保障电网稳定性的重要手段。针对这一问题,本研究首先分析交直流混合微电网的特点及系统架构,随后提出一种交直流混合微电网并网运行控制策略,主要解决交直流混合微电网中功率波动、交直流系统之间功率平衡等问题。在该策略中,孤岛运行阶段蓄电池为平衡点,与双向AC/DC变换器维持系统电压及频率,实现交直流系统功率平衡控制。交直流微网运行控制中综合考虑了降低能量损耗、提高能源利用率等问题。In order to solve the problem of energy shortage,the development and application of renewable energy have become a research hotspot.Among them,the AC-DC hybrid microgrid is an important way to achieve energy supply and demand balance and ensure grid stability.In response to this issue,this study first analyzes the characteristics and system architecture of the AC-DC hybrid microgrid,and then proposes a control strategy for the grid connected operation of the AC-DC hybrid microgrid,mainly solving problems such as power fluctuations and power balance between AC-DC systems in the AC-DC hybrid microgrid.In this strategy,during the islanding operation phase,the battery serves as the balance point and maintains the system voltage and frequency with the bidirectional AC-DC converter to achieve power balance control of the AC-DC system.The operation control of AC-DC microgrids comprehensively considers problems such as reducing energy loss and improving energy utilization efficiency.
