Comprehensive energy system multi-target fuzzy optimization method in consideration of exergy efficiency

Abstract

The invention provides a comprehensive energy system multi-target fuzzy optimization method in consideration of exergy efficiency. The optimization method comprises the following steps: on the basis of acquiring a structure of a comprehensive energy system, an energy module unit, and various load information, establishing various energy module unit models, and then establishing an exergy flow analysis model, wherein the exergy flow analysis module comprises an input exergy flow analysis model and an output exergy flow analysis; and meanwhile, arranging a running constraint condition, wherein the constraint condition comprises capacity constraint, climbing constraint, and energy balancing constraint; secondly, establishing a single-target optimization model, wherein the single-target optimization model comprises an economic type optimization model, a comprehensive exergy efficiency optimization model, and an environment-friendly optimization model. Based on the above conditions, the multi-target fuzzy optimization model is established; and finally, a model program is compiled based on a LING8.0 software platform, and a global solver is called for solving the established multi-targetfuzzy optimization model. The effectiveness for the running optimization of the comprehensive energy system is verified through example analysis, thereby providing guidance significance for the multi-scene optimization of the comprehensive energy system.
