Embodiment Construction

[0035] see Figure 1-6 , a plurality of charts related to the embodiment of the present invention, the region involved is the Xinjiang region, and are used to illustrate the implementation mode and effect of this embodiment.

[0036] 1. Realization of day-ahead spot volume price strategy generation algorithm technology

[0037] First of all, based on the historical cleared electricity of the whole network, the total amount of cleared electricity of the whole network on the next day is predicted. The prediction uses BP neural network as the prediction model.

[0038] Secondly, based on the historical power generation data from the station side of the centralized control system, the wind power generation and curtailment data of the wind farm on the day, and the wind power prediction results of the next day, combined with the grid structure, the tradable abandoned wind power of the next day is predicted, and the algorithm is used The next day’s 96-point volume-price curve for e...

Abstract

The invention provides a cross-regional day-ahead spot goods automatic transaction strategy method, which comprises the following steps of: predicting the total clearing electric quantity of the wholenetwork of the next day by using a BP neural network on the basis of the historical clearing electric quantity of the whole network; predicting the next day tradable abandoned wind power according tothe historical power generation data of the centralized control system station side, the current day power generation and limit data of the wind power plant and the next day wind power prediction result in combination with the grid structure condition, respectively generating a next day 96-point quantity price curve of each station, and taking the tradable electric quantity as a basis for reporting the electric quantity; calculating the declared electricity price according to the ratio of the tradable electricity quantity of the station side to the whole network clearing electricity quantitypredicted next day and the historical clearing electricity price distribution; and automatically declaring the generated price curve to a power grid information interaction platform by utilizing a timing task in a transaction declaration effective time period. The invention further discloses a trans-regional day-ahead spot goods automatic transaction economy evaluation method, and the actual economic benefits of participating in the spot goods transaction are obtained.

Description

technical field [0001] The invention belongs to an electric power system, and in particular relates to a cross-region day-ahead spot automatic trading strategy and an economic evaluation method. Background technique [0002] In order to solve the power consumption problem of Xinjiang's new energy power plants and reduce the phenomenon of abandoning wind and solar power, the Xinjiang dispatching center began to organize cross-regional day-ahead spot trading of abandoned wind power in August 2017. The surplus power in the region is transmitted to the central and eastern provinces with power shortages to better balance regional resources. [0003] Cross-region day-a-day spot transactions are carried out at the "Xinjiang Factory Network Information Interaction Platform" of the Xinjiang Dispatch Center. The staff of the new energy station will manually determine the quotation strategy by referring to the data of the previous day’s power generation, power cuts, and wind power for...
