Abstract:
With the rapid development of new distribution systems(DSs), the interdependence between distribution networks and communication networks is gradually deepening. After extreme disasters occur, on the one hand, the restoration control relies on the effective support of the communication network after black-out of the distribution network, and the process of using vehicle to grid(V2G) to restore load power supply after disasters cannot be separated from the guiding role of the communication networks. On the other hand, the normal operation of communication networks depends on the power supply of the distribution network. Therefore, to solve the problem of load restoration under the interaction between distribution network and communication network after a disaster occurs, a fast recovery method for distribution network through cyber-physical collaboration based on V2G and emergency communication is proposed. After disasters occur, an emergency communication network is established by deploying unmanned aerial vehicles equipped with wireless communication base stations to the communication-failure area to quickly restore the control of automated switches and guidance to electric vehicles(EVs). Then, EVs are guided to the V2G station to form the distributed generators and control the topology of DSs to restore power to the loads. The proposed method is based on the scheduling constraints of post-disaster unmanned aerial vehicles and EVs, as well as the operational constraints of DSs, in which a cyber-physical integrated DS restoration model is built, and the effectiveness of the proposed method is verified through a DS and transportation network integrated case.
