Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific calculation examples.

[0042] In the present invention, i and j are counting variables and have no physical meaning.

[0043] Firstly, a complete set of evaluation index system is constructed; secondly, the proposed index is standardized and calculated; on this basis, the weights are calculated by using the AHP and the entropy weight method respectively, and the AHP and the entropy weight are combined by the game theory. Finally, based on the improved PageRank method, considering the mutual influence between the evaluation indicators, the optimized weights are obtained to evaluate the clearing method. Through the evaluation of the "Northwest-Shandong" mid- and long-term centralized electricity trading examples, the effectiveness and accuracy of the proposed improved PageRank method are verified.

[0044] Specifically include the following steps: ...

Abstract

Based on the improved PageRank evaluation method of power market clearing mode, firstly, the evaluation index system is constructed; secondly, the indexes of the index system are standardized. Then itevaluates with AHP and entropy weight method, and synthesizes the weights obtained by AHP and entropy weight method. Finally, based on the improved PageRank method, considering the mutual influence relationship between the evaluation indexes, the optimized weights are obtained, and the evaluation of the clearing way is carried out. The invention avoids the one-sidedness of adopting a certain evaluation method, Considering the subjectivity and objectivity of the evaluation, and considering the interaction between the indicators, this paper calculates the transfer weight, corrects the existingindex weights, evaluates the marginal unified clearing and high-low matching clearing, and obtains more accurate and objective evaluation results of the two clearing methods. Through verification, thepresent invention has the validity and accuracy of evaluation.

Description

technical field [0001] The invention belongs to the field of electric power market, and relates to an evaluation method for clearing mode of electric power market based on improved PageRank. Background technique [0002] The transaction mechanism of the electricity market directly affects the operation results of the electricity market. As a key issue in the transaction mechanism of the electricity market, the clearing method of the market is in urgent need of in-depth research. The current clearing methods mainly include marginal unified clearing and high-low matching clearing. It is very necessary to evaluate the advantages and disadvantages of these two clearing methods in various aspects. [0003] In terms of evaluation objects, most of the existing evaluation problems in the field of electricity market focus on the operating efficiency of the electricity market, the transaction mechanism of the electricity market, and the market behavior of participants in the electric...
