Optimal operation of hybrid energy systems is a big challenge in power systems. Nowadays, in addition to
the optimum performance of energy systems, their pollution issue has been a hot topic between
researchers. In this paper, a multi-objective model is proposed for economic and environmental operation of a battery/fuel cell/photovoltaic (PV) hybrid energy system in the presence of demand response
program (DRP). In the proposed paper, the first objective function is minimization of total cost of hybrid
energy system. The second objective function is minimization of total CO2 emission which is in conflict
with the first objective function. So, a multi-objective optimization model is presented to model the
hybrid system’s optimal and environmental performance problem with considering DRP. The proposed
multi-objective model is solved by e-constraint method and then fuzzy satisfying technique is employed
to select the best possible solution. Also, positive effects of DRP on the economic and environmental performance of hybrid system are analyzed. A mixed-integer linear program is used to simulate the proposed model and the obtained results are compared with weighted sum approach to show the
effectiveness of proposed method.
