摘要

Hospital is one of the potential facilities that couldrnemploy cogeneration system. This high efficiency energyrnconversion system could offers a lots of benefit especiallyrnsavings on the energy used. Furthermore, it is veryrneffective compared to centralize bulk generation if it isrnsited near the load. To reap the maximum benefit, arncogeneration system must be optimally sized.rnThis paper presents a study of cogeneration system forrntypical hospital buildings in Malaysia. A mixed integerrnnon-linear optimization technique is used to size thernsystem. A Newton Raphson and Conjugate method havernbeen used in the optimization process. The optimizationrntechnique models the cogeneration system together with arnthermal storage system that will provide broader spectrumrnin the optimization exercise.rnHospital facility with maximum demand of 5 MW andrn2 MW are simulated. The annual savings will bernoptimized operationally by varying hourly generationrnoutput. Matching the generated electrical and thermalrnenergy to the load will be optimized. Having thermalrnstorage in the model will enhance the matching procedurerntowards better overall efficiency. Five different capacitiesrnof gas turbine generator that are available commerciallyrnare used in the simulation to determine the choice ofrnoptimal size system. This model and its solution arernsuitable for cogeneration facility planning study.
