In this article, we have optimized the total operational cost of combined cooling heating and power system (CCHP). This cost is further divided into three major parts, which are the capital cost of the equipment, fuel cost, and the grid electricity cost. The heat storage tank has also been used to store the excessive heat that can be utilized when needed. A genetic algorithm has been used for the optimization of the whole system. The decision variables chosen were 74. The optimization resulted in significant reduction in the total cost. The final results show that the cooling demand was significantly supplied by the Grid through the electric chillers because of higher coefficient of performance, while the power demand was met through the power generation unit. Results shows that the natural gas cost consumption is much greater then the grid and equipment cost.
