Abstract

The invention provides a node marginal electricity price interval determination method and device. The method comprises the following steps: generating a plurality of clearing electricity price scenesbased on obtained historical quotation information and historical load information; determining a clearing electricity price corresponding to each clearing electricity price scene; and determining the node marginal electricity price interval based on the lower limit and the upper limit of the clearing electricity price. The historical quotation information of the power generator and the historical load information of the load node are considered, so that the accuracy of the node marginal electricity price interval is greatly improved; according to the technical scheme provided by the invention, the uncertainty of the quotation of the power generator and the node load in the process of determining the marginal electricity price of the node is considered, and the marginal electricity pricecondition of the power market node is well reflected; the quotation scene of the power generator and the load scene of the load node are generated, and the clearing electricity price scene is generated through the quotation scene of the power generator and the load scene of the load node, so that the node marginal electricity price interval prediction precision can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of electric power automation, in particular to a method and a device for determining a node marginal electricity price interval. Background technique [0002] Electricity price is the core embodiment of the economy in the electricity market mechanism and an important indicator in electricity market transactions. Accurate electricity price forecasting is of great significance to all members of the electricity market. It not only provides a basis for planners to formulate dispatch plans, provides a basis for market supervision by the government, but also provides a basis for power plant investors to select plant sites and conduct risk assessment. In addition, accurate electricity price prediction can also enable generators and electricity purchasers to choose better quotations to obtain more profits. Therefore, electricity price prediction plays an important role in electricity market research, and electricit...
