Method of Optimization and Multi-criteria Evaluation of Distributed Combined Cooling Heating and Power Energy System

Different energy systems were developed on the basis of the major equipment of distributed energy systems (DES). According to the demand of loads, energy prices, and technical and financial information about optional technologies, using non-linear programming, an optimization model for DES was established. The optimum configuration, optimal operation scheme and evaluation criteria matrix were the results of the model. The information entropy was used to determine the weight distribution, then the multi-criteria comprehensive evaluation method was introduced. The results demonstrate that photovoltaic system is optimal scheme due to its lower cost, energy conservation and environmental protection.
