| 摘 要： | 针对三相不平衡的单/三相交直流混合微网，直流微网内分段下垂的自治分布储能系统和交直流微网接口变换器的区域电能均衡的能量管理策略被分别设计以实现均衡功率和提高可再生能源利用率。首先，单/三相交直流混合微网的拓扑结构及其功率交换模式被建立。然后，针对基于分段下垂曲线的储能系统易出现的局部环流、难以实现分布式电源和负载即插即用等问题，设计了一种动态均衡的荷电状态一致性策略。提出了计及恒功率交互、混合微网电压、频率稳定性，基于分段下垂的自治分布储能系统与区域电能均衡策略的协调控制方法。最后，通过仿真和实验验证了所提能量管理策略的有效性。

| Abstract: | For the unbalanced three-phase of single/three-phase AC/DC hybrid microgrid, an autonomous distributed storage system based on segmented droop control in the DC microgrid and a regional power balance management strategy of the interfaced converter in hybrid AC/DC microgrid are designed to realize the balanced power and the improvement of renewable energy utilization rate. Firstly, the topology and power exchange mode of single-phase/three-phase AC/DC hybrid microgrid are established. Then, a dynamic equilibrium of state of charge consistent strategy is designed to address the issues of local current circulation, which is prone to energy storage systems based on segmented droop curves, the plug-and-play of power supply and load in distributed generator. Furthermore, considering the constant power interaction and voltage/frequency stability of hybrid microgrid, a coordinated control strategy is proposed based on a regional power balance management strategy and an autonomous distributed storage system with segmented droop control. Finally, the effectiveness of the proposed approach is verified by extensive simulations and experiments. |
