The large-scale grid connection of distributed generation (DG) not only brings the problem of consumption,but also poses great challenges to the economic and safe operation of the AC/DC network. Based on this,an optimal operation method for AC/DC hybrid distribution network based on DG location and coordinated control of multi-terminal voltage source converter (VSC) is proposed. For DG location,a node loss sensitivity index is proposed through the sensitivity analysis method. The DG location on the AC network side is carried out by using the law that load nodes at different locations have different sensitivities to network loss.Then,a multi-objective optimization model aiming at minimizing network active total loss,node voltage deviation and DG surplus is established to coordinate the active power output of DG and the port power and voltage variables under different control modes of multi-terminal VSC. The simulation results show that the proposed optimal operation method can improve the economy and security of network operation while taking into account the DG consumption level of distribution network,and provides an important reference for decision-makers in practical engineering.
