Abstract

The invention discloses a method and a system for adjusting node electricity prices in consideration of a virtual power plant in a region. The method includes the following steps: S1. Obtaining the operating boundary conditions of the power grid and the outsourced load data of power consumers; S2. Constructing a spot transaction clearing model , optimize the calculation, and determine the power generation plan; S3. Determine the node power price according to the power generation plan, grid operation boundary conditions and outsourced load data of the power consumer; S4. Determine whether the node power price meets the spot transaction strategy; Yes, go to step S5; No, Proceed to step S6; S5. Output the regulation strategy of the virtual power plant, and adjust the node electricity price according to this strategy during the spot transaction; S6. Change the size of the power generation load through the control system of the virtual power plant. The invention utilizes the distributed energy facilities on the user side in the area to form a virtual power plant with a relatively large adjustment capability, thereby adjusting the node electricity price and satisfying the power spot transaction strategy of the electricity retailing company.

Description

technical field [0001] The invention belongs to the field of electric power trading, and in particular relates to a method and a system for adjusting node electricity prices in consideration of virtual power plants in an area. Background technique [0002] At present, the Guangdong electric power spot market has carried out settlement on a daily trial basis. The spot market settlement is settled according to the node electricity price. The node electricity price refers to the increase of unit load demand at a certain node under the condition of meeting the operating characteristics and constraints of various equipment and resources. The hourly marginal cost represents the increased cost required to consume more kilowatt-hours of electricity at a certain time and place. The trading strategies formulated by the participating members of the electricity market depend on the forecast of node electricity prices. The accuracy of node electricity price forecasts is very important to...
