Multi-objective operation optimization of micro-grid based on electro-thermal coupling constraints

摘要

The concept of the Energy Internet was presented to optimize the utilization of multiple types of energy. This paper mainly focuses on the optimization operation problems of micro-grid under electro-thermal coupling constraints. Based on the electric and thermal energy system models, including CCHP, electro-refrigeration and so on. this paper focuses on improving the thermal network constraints, and establishes the optimization model with electro-thermal coupling constraints. And then, after verifying the effect of 3 types of single objective optimization, this paper carries out multi-objective optimization by using Pareto Front Theory and presents the selection strategy of the corresponding optimized operation plan in the Pareto Front Set.
