Application of Comprehensive Energy System in Value Evaluation of Iron and Steel Enterprises

Abstract

Industrial and commercial enterprises are the main group of energy consumers, and objectively and accurately evaluating the value of their comprehensive energy system is the basis for optimizing operation and energy auditing. Traditional evaluation methods have shortcomings in promoting multi energy complementarity and renewable energy consumption. Propose a comprehensive energy system value evaluation method based on green economy, objectively and quantitatively calculate based on enterprise energy balance management standards, considering three evaluation indicators: product unit consumption, comprehensive energy efficiency, and renewable energy utilization rate. Using the fuzzy comprehensive evaluation method, the membership functions and dynamic weight coefficients of three indicators are designed to obtain a comprehensive value score, and the optimal operation plan is selected based on the score. The simulation results indicate that the evaluation method can select a reasonable operating mode based on the energy consumption pattern of the enterprise, promote the cascade utilization of energy and the on-site consumption of renewable energy, and verify the effectiveness and rationality of the method.
