With the increasing scale of distributed power sources

the problem of local new energy consumption has become prominent. It is an effective way to solve the problem by adopting the strategy of coordinated control of source network and load and by adjusting the load side voltage to change the load power. In this paper

a novel multi-line fast electromagnetic Sen-transformer with compact structure

quick adjustment

good economy

and high reliability is first proposed

and its topology and control strategy are analyzed. Then a simulation model of typical distribution network and MFE–ST in Simulink is established

and the simulation analysis is carried out under various conditions. Finally

a small capacity test model of MFE–ST is developed

and an experimental platform of distribution network is built to carry out the experiment. The simulation and experimental results show that the maximum relative errors of MFE–ST in regulating power flow active power and reactive power are 6.72% and 4.84%

respectively. The compensation effect and accuracy are expected

and MFE–ST can realize the power decoupling control

which verifies the feasibility and effectiveness of the MFE–ST proposed in this paper.
