Abstract

The invention discloses a method and a system for adjusting node electricity price by considering a virtual power plant in a region. The method comprises the following steps: S1, acquiring a power grid operation boundary condition and electricity enterprise purchase load data; S2, constructing a spot transaction clearing model, performing optimization calculation, and determining a power generation plan; S3, determining a node electricity price according to the power generation plan, the power grid operation boundary condition and the electricity enterprise outsourcing load data; S4, judging whether the node electricity price meets a spot transaction strategy or not, executing S5 if the node electricity price meets the spot transaction strategy, and otherwise, executing S6; S5, outputtinga virtual power plant adjustment strategy, and adjusting the node electricity price according to the strategy during spot transaction; and S6, changing the size of the power generation load through avirtual power plant control system. According to the invention, distributed energy facilities on the user side in a region are utilized to form a virtual power plant with relatively high adjustment capability, so that the node electricity price is adjusted, and the power spot transaction strategy of the electricity selling company is satisfied.

Description

technical field [0001] The invention belongs to the field of electric power trading, and in particular relates to a method and system for adjusting node electricity prices in consideration of virtual power plants in the region. Background technique [0002] At present, the Guangdong electric power spot market has carried out settlement on a daily trial basis. The settlement in the spot market is settled according to the node electricity price. 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 the participants of the electricity market. How to dynamically adjust node electricity prices to dynamically meet the needs of electricity sales companies and electricity consumers The tradin...
