(186o) A Novel Methodology to Optimize the Operation of Combined Cooling Heat and Power Systems

This work presents a novel methodology to optimize the operation of CCHP systems. We introduce a novel performance curve (NPC) which enables determinations of optimal operating strategies and show that previously operating strategies are the special cases of our methodology. The PGU overall optimum partial loads for demands below and above the CCHP operating curve are determined based on the optimization criteria and system characteristics. The proposed methodology is flexible and adaptable; it accounts for energy prices, carbon dioxide emissions (CDE), primary energy consumption (PEC) factors and load variations with the weather conditions. The operating of the CCHP system is analyzed for small hotel buildings in San Francisco and Miami having different energy demand profiles. These locations have different energy prices, CDE and PEC factors. The proposed methodology leads to the best operation when compared to following electrical load and following thermal load strategies based on operating cost, carbon dioxide emissions, primary energy consumption and a combination.
