碩士 === 大同工學院 === 電機工程研究所 === 81 === Economic dispatch for cogeneration system is to get the optimal operation strategy and minimize the overall operation cost subject to satisfying the demand of process steam and electrical load. This thesis proposes an optimal method based on Newton-Rapson method for economic dispatch. The cogeneration system can be divided into two parts : one is the steam system, and the other is the electric system. The steam system is to perform economic dispatch for boilers and minimize the overall cost of all fuels subject to satisfying the demand of high- pressure steam. The electric system is to minimize the electric cost after considering time-of-use rates and various constraints that applied on real system subject to satisfying the demand of process steam in first priority and electric load. A real cogeneration system is cited as an example to verify the availability of the proposed method.
