Financial issues have been always one of major priorities in scheduling of energy systems. Although these
systems are able to serve several types of energy demands but generated emission by these systems is a challenging problem. Since improvement of each one of mentioned issues has negative effects on the other issue
therefore a trade-off solution is necessary to be obtained between these issues. In this paper, a multi-objective
model has been presented to satisfy both economic and environmental objectives of a hub energy system in the
presence of demand response program. In the proposed paper, ε-constraint and max–min fuzzy satisfying
methods have been employed to solve and select the trade-off solution. The main reason of implementation of
demand response program is to reduce operation cost and improve environmental performance of hub energy
system. In fact, demand response program transfers some percentage of load from peak periods to off-peak
periods to flatten load curve which leads to reduction of cost and emission. A mixed-integer linear programming
has been used to simulate the proposed model and general algebraic modeling system software has been utilized
to solve it. A sample hub energy system containing renewable and non-renewable energy resources has been
studied and comparison results are presented to validate efficiency of proposed techniques.
