By aggregating the flexible resources on the demand side

the virtual power plant can effectively stabilize the power system fluctuations when the new energy generation is high. In addition

considering the scale and accuracy of new energy power generation

the consumption in the zone can no longer meet the requirements of new energy development. Moreover

modes such as centralized clearing cannot adapt to the characteristics of new energy that can be used immediately. Based on this

on the basis of the existing inter-provincial trading mechanism

the form of demand-side virtual power plant is introduced as a new type of market user

and the transaction strategy of virtual power plant participating in the intra-day listing of inter-provincial green power is proposed

and the effectiveness of the proposed strategy and model is verified by case analysis

which is helpful to realize the mutual aid of cross-regional resources.
