A multi-objective optimization model for urban energy systems in a specific area

Considering CO₂ emission, energy consumption and economic indices as evaluation factors, this paper proposes a new multi-objective optimization model for determining urban energy systems in a specific area. The proposed model is applied to an actual city in Japan, and the tradeoff relation among three indices is analyzed. The results show the roles of the energy system alternatives from viewpoints of CO₂ emission and primary energy consumption, respectively.
