N2 - To improve the frequency response of the distribution system after extreme natural disasters, a distribution system recovery method based on virtual synchronous generator (VSG) technology is proposed to solve the problem of frequency stability caused by large-scale distributed new energy generators access in the distribution system after extreme disasters. Firstly, a mathematical model is established to control the interface inverter of distributed new energy generators using VSG. Secondly, based on the rotor motion equation and the mechanical power response model of the generator, the expressions of the initial frequency change rate and the lowest frequency of the system are derived, which are used as the frequency constraints in the post-disaster recovery process of the distribution system, and the linearization method of nonlinear constraints is given. Then, in order to maximize the load-weighted recovery, taking into account operational constraints, frequency constraints, and topology constraints, and the post disaster load recovery problem of the multi-time distribution system is modeled as a mixed integer linear programming (MILP) model, and solved using a commercial solver. Finally, the effectiveness and superiority of the proposed recovery method are verified by the improved IEEE 13 node and IEEE 37 node distribution system standard examples.
