Abstract

In this paper, using a thermodynamic rules, a Multigeneration Energy System with an initial stimulus of Microturbine has been modeled. Then, using the concept of exergy and applying economic and environmental functions, exergy efficiency and total cost rate are calculated as two objective functions. Due to the contradiction of the objective functions, a multiobjective firefly algorithm is used to optimize the system. To accelerate the process of optimization and to prevent algorithm capture in local optimizations, new algorithms have been added to the innovative algorithm. The result of applying the algorithm on the Multigeneration Energy System will result in a set of Pareto-optimal solutions, indicating the compromise between the target functions. A fuzzy decision making based on max-min approach is used to select the desired solution between the Pareto-optimal solutions. In order to evaluate the efficiency of the proposed optimization algorithm, the results of this algorithm are compared with two particle swarm optimization algorithms and multi-objective genetic algorithm. Based on the results of system optimization, the exergy efficiency can increase up to 69%. Also, considering the total cost rate of the system as the only target function, this can be reduced to 572$/h.
