摘要：

混合配电变压器是由工频多绕组变压器与电力电子变换器组合构成的新型智能变压器，可以作为交直流配电网中台区能量转换核心。为此，对基于混合配电变压器集群互联的交直流配网系统结构进行分析。针对交直流配电网中混合配电变压器台区间互联端口的功率分配问题，提出基于时间一致性算法的混合配电变压器互联系统功率分配策略。在保持台区和配电网系统内功率平衡的同时，实现不同台区间的分布式电源消纳和功率互补。同时，对一致性算法的应用使每个台区在稀疏通信方式下，仅与相邻台区通信即可获取全局信息，为分布式控制提供基础。最后通过Matlab仿真验证了所提控制策略的有效性。

Abstract:

Hybrid distribution transformer is a new type of intelligent transformer, which is composed of power frequency multi-winding transformer and power electronic converter. Therefore, the structure of AC/DC distribution network based on hybrid distribution transformer cluster interconnection is analyzed. Aiming at the power distribution problem of interconnecting ports of hybrid distribution transformers in AC and DC distribution networks, a power distribution strategy of interconnecting system of hybrid distribution transformers based on time consistency algorithm is designed. The distributed power consumption and power complementarity of different stations are realized while the power balance between the stations and the distribution system is maintained. At the same time, the application of the consistency algorithm enables each station to obtain global information only by communicating with neighboring stations under the sparse communication mode, which provides the basis for distributed control. Finally, the effectiveness of the proposed control strategy is verified by Matlab simulation.

Key words: Hybrid distribution transformer, consistency algorithm, interconnect port, power distribution strategy
