摘　　要：针对一种可接入分布式新能源发电系统的模块级联型三端口单相电力电子固态变压器电路拓扑,提出了一种功率/潮流均分控制策略,实现了高压电网侧端口、低压交流用户侧端口及400V直流侧端口三者之间电能双向自由流动,并且优先使用分布式新能源的电能;同时,实现了高压电网侧端口单位功率因数。理论分析、仿真及实验均验证了所提出的新型电力电子固态变压器控制技术方案的良好性能与可行性。Aiming at a modular cascaded three-port single-phase solid state transformer circuit topology that can access distributed new energy power generation system,a power/power flow balancing control strategy is proposed to realize the two-way free flow of electric energy between high-voltage grid side ports,low-voltage AC user side ports and 400 V DC side ports,and priority to the use of distributed new energy is given.At the same time,the unit power factor of side port in high voltage network is realized.Theoretical analysis,simulation and experiment verify the good performance and feasibility of the proposed new solid state transformer control technology.
