The Effects of Electricity Boiler on Integrated CCHP-Thermal-Heat Only Unit Commitment Problem Based on Hybrid GA Approach

Combined cooling, heat, and power (CCHP) units can be integrated with conventional separate cooling, heat, and power production units to meet demands. The goal of this study is to develop and examine a hybrid GA-heuristic optimization algorithm for solving the unit commitment problem for integrated CCHP-thermal-heat only system with considerations for electricity boiler. When environmental emission cost and valve-point effects are considered, the utilization of CCHP units in an integrated CCHP-thermal-heat system results in environmental emission and total cost reduction by and 38.37 and 0.03% respectively. Also, using electricity boiler, environmental emission and total cost reduction of 0.53 and 0.03 are reached, respectively.
