Abstract:With the rapid growing of electric vehicles penetration in the active
   distribution network, the unconstrained or unguided consumption behavior
   is not conducive to the control of the power balance of the distribution
   network, it can even cause the network congestion. However, the EV
   fleets charging methods can be easily adjusted under the management and
   adjustment of the electric power market model. In this view, an active
   distribution network congestion dispatching model was proposed, which
   was based on the flexible charging/discharging temporal transference
   ability of EVs. Under the consideration of probability characteristics
   of intermittent distributed generation and EVs, the pattern was set up
   based on an operation pattern of adjusting the charging fees. The
   pattern was based on the real situation of our nation's electricity
   market, and it aimed to realize the bidirectional response control of
   distribution system operator and charging/discharging infrastructure
   operator. Thus, EV owners can be guided to make a reasonable
   charging/discharging schedule to realize the congestion management of
   active distribution network. The example shows that the congestion
   dispatching strategy mentioned in this paper can be implemented to
   reduce the degree of congestion, it can also enhance the security and
   economic operation of the network.
