Abstract
Combined cooling, heat, and power systems (CCHP) employ energy integration strategies to satisfy the energy demands (refrigeration, heat, and electricity) of consumer centers. Due to the wide availability of energy conversion technologies, there are numerous ways to meet energy demands, from more traditional systems to more complex, exotic configurations. An optimal result depends on several factors, such as fuel and electricity tariffs, capital costs of equipment, energy demands, and legal constraints. Also, the desired goal of the project influences the most appropriate scenario to meet the demands. When optimizing CCHP systems, the objective function can be the minimization of costs (financial metrics), maximization of profits (financial metrics), or the minimization of carbon emissions (environmental metrics). The introduction of indigenous renewable resources in energy systems can bring economic benefits, reducing operating costs, but above all, environmental benefits can be obtained due to the low operational emissions of renewable technologies. Financial and environmental metrics are frequently divergent, and this study proposes a bicriteria optimization of a CCHP system, considering renewable resources (solar and wind). The linear programming model proposed herein considers a combination of financial and environmental metrics and also evaluates the impact of fuel rate variation on costs and carbon emissions.
