Thermal load entropy weight fuzzy risk assessment method based on electric power spot market transaction

Abstract

The invention belongs to the field of methods for evaluating risks of thermal load participating in electric power spot market transaction, and particularly relates to a thermal load entropy weight fuzzy risk evaluation method based on electric power spot market transaction. The method comprises steps of determining a risk evaluation set and a comment set of thermal load participating in electric power spot market transaction; standardizing the thermal load participating in the electric power spot market transaction risk evaluation matrix; determining an entropy weight set and a comprehensive weight set of the thermal load participating in the electric power spot market transaction risk index; constructing a fuzzy evaluation matrix of the electric power spot market transaction risk participated by the thermal loads of different regions; solving a comprehensive evaluation fuzzy subset; and sequencing the conditions of the electric power spot market transaction risks participated by the thermal loads in different regions by using a fuzzy comprehensive evaluation result. According to the method, evaluation is more accurate and objective, and a scientific risk evaluation means is provided for participation of thermal load in electric power spot market transaction.

Description

technical field [0001] The invention belongs to the field of risk assessment methods for thermal loads participating in electric power spot market transactions, and in particular relates to a thermal load entropy weight fuzzy risk assessment method based on electric power spot market transactions. Background technique [0002] With the continuous acceleration of my country's electricity marketization reform, the new round of electricity marketization construction has been fully accelerated, and many positive progresses have been made. As one of the indispensable links in the modern power market system, the spot market plays the role of real-time power balance, guiding the investment and construction of power grid power supply, and providing price signals for other power trading varieties. However, in the spot market environment, thermal loads participate in the power Spot market transaction risks are characterized by multiple forms, great influence and difficult supervision....

AI Technical Summary

Problems solved by technology

[0005] The fuzzy risk assessment method of thermal load entropy weight based on the power spot market transaction effectively solves the shortcomings of the poor objectivity of qualitative method evaluation. The coefficients are combined in a more reasonable weighted way, and the relative importance of the two weights is further considered, the evaluation is more accurate and objective, and it provides a scientific risk assessment method for heat loads to participate in power spot market transactions
