ガスエンジン・コジェネレーション・プラント用CAPシステムの開発

The objective of this study is to develop a computer-aided optimal planning (CAP) system for the initial design of a cogeneration plant composed of gas engine driven generators. electric and gas refrigerators, gas engines and electric driven heat pumps. gas boilers, single-effect refrigerators, heat exchangers. etc. In the CAP system, first, energy demand categorized by electric power, space heating and cooling, and hot water supply together with the configuration of the plant's equipment and the tariff of fuel are determined. To execute the optimal operation of the cogeneration plant, the load allocation problem is investigated based on the mixed-integer linear programming method by adopting zero-one integer variables, indicating the on/off status of operation, together with continuous variables indicating the operational level of each equipment. Lastly. the economical evaluation of the plant is done based on the annual cost method.
