Embodiment 1

[0053] In the first embodiment, the specific content of step S1 is: according to the historical output data of renewable energy, the "elbow method" and the silhouette coefficient method are combined to determine the optimal number of clusters of the K-means clustering method to obtain a plurality of renewable energy sources. Typical output curve and the corresponding output curve scenario probability.

[0054] Among them, the main idea of ​​the elbow method is to gradually increase the number of clusters starting from k=2, and calculate the sum of the distances between all sample data points and their corresponding data set centers. Further increasing k, the sum of distances will gradually converge to a stable level, and this k value is the true number of clusters.

[0055] The silhouette coefficient method performs well in practical experiments. The concept of silhouette coefficient is related to the compactness of data within a class and the degree of dispersion of data betw...

Abstract

The invention provides a balanced optimization device based on an electric power green certificate market joint clearing model, and the device is based on a computer system and a program, and executes the following technical design: according to the historical output data of renewable energy sources, extracting a renewable energy source output characteristic curve through clustering analysis and other algorithms; setting parameters such as weight indexes of power consumers, basic parameters of each market subject, probabilities of different scenes, unit output, load fluctuation and the like under a renewable energy source forehead system; performing linearization processing on the power-green certificate market joint clearing model to convert the power-green certificate market joint clearing model into a solvable mixed integer linear programming model; in a pre-established power-green certificate market combined clearing model, quotation parameters of a strategy quoter are initialized, and the power-green certificate market combined clearing model is solved through a diagonalization algorithm, so that an optimal value for balanced optimization in the model is obtained; comprising market clearing electricity price, bid-winning capacity of each market subject, an optimal quotation strategy of a strategy quoter and the like.

Description

technical field [0001] The invention belongs to the technical field of electric power trading systems and devices, and in particular relates to a balanced optimization device based on a joint clearing model of the electric power green certificate market. Background technique [0002] The reform of the power system was further deepened, and eight pilot provinces took the lead in building a spot market for electricity, which further improved the degree of openness of the electricity market. In the future, as the proportion of renewable energy power marketization gradually increases, the uncertainty, volatility, intermittency and green certificate market of renewable energy power will have a profound impact on the equilibrium results of the power market. Therefore, the study of renewable energy quotas The electricity market is of great significance under the background of the parallel system and the electricity spot market. At present, the electricity market model basically onl...
