Multi-dimensional risk assessment of electricity market based on cloud model

Abstract

Aiming at various potential risks in the electricity market, this paper establishes a risk assessment index system for the electricity market from four dimensions of structural risk, operation risk, fairness risk, and behavioral risk. The analytic hierarchy process is used to determine the subjective weight of risk evaluation indicators, and the entropy method is used to determine the objective Weight, according to the least squares optimization idea to get the comprehensive weight. Then, the basic theory and calculation method of cloud model are introduced, and the standard cloud of risk level evaluation is constructed. Finally, the analysis of a calculation example shows that the risk evaluation level of the selected regional electricity market is moderate, which verifies the validity and feasibility of the model proposed.
