In this paper, optimal heat and power dispatch of the fuel cell (FC) and combined heat and
power (CHP) based microgrid (MG) in grid-connected mode is studied in the presence of
demand response program (DRP). Considering cost and emission minimization has turned
this study to a multi-objective problem. Multiple generating and storing units such as FC,
CHP, power-only unit, boiler, battery storage system, and heat buffer tank are considered
in investigated MG. Also, demand response program has been modeled, and the effects of
such programs on the load profile have been discussed. The DRP transfers some amount of
load from peak periods to other periods which flats the load curve and minimizes total cost
and emission of the MG. To solve the multi-objective optimization problem, the Pareto
solutions are generated by using the compromising programming, then, optimal solution is
chosen by implementing the fuzzy satisfying approach. In comparison with other
methods, the proposed method has reduced the set of efficient solutions to a more
reasonable size without demanding any information about the decision making parameters.
Finally, the problem is solved in two cases as with and without DRP to clarify the
impact of DRP on MG scheduling.
