碩士 === 國立中正大學 === 電機工程研究所 === 105 === In recent years, power industries have been aggressive in reducing costs or improving operation efficiency because of higher international energy's prices. Fortunately, gas power generation benefit from the realization of the combined cycle technology, which greatly improve the power generation efficiency. However, it will become more difficult to do electrical dispatch when a large of combined cycle units are built. In this thesis, Pyomo is adopted to establish unit commitment model with short-term scheduling of combined cycle plants and thermal units by considering Minimum cost and generator characteristics including combined cycle unit’s Equivalent Operation Hour. The mathematical model proposes Mixed Integer Linear Programing (MILP) for based approaches, and piecewise linear approximation is used to get units input/output curves.
