Description

Technical Field

[0001] The present invention belongs to the technical field of electric power, and particularly relates to a regional energy power allocation method and system considering end-to-end green power trading. Background Art

[0002] With the enhancement of global environmental protection awareness, the green and low-carbon transformation of energy has been accelerating continuously. On the supply side, promoting the construction of new energy in an orderly manner under the background of the rapid development of new energy can effectively promote the consumption of new energy and the efficient utilization of resources; on the consumption side, with the continuous increase in the demand for green power by electricity users, the scale of green power trading has also increased rapidly. Avoiding the double counting of environmental attributes in the process of promoting new energy to participate in the power market will protect the legitimate rights and interests of both parties in green power trading and promote the healthy development of the green power market.
