| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 98 === In this thesis, the optimal power dispatch planning considering the emission of carbon dioxide (CO2) is presented. First, different CO2 equivalent models for fossil fuel generating units are derived. Secondly, two index, the Cost-CO2 emission Tradeoff Curve (CCTC) and Incremental Cost for CO2 Reduction (ICCR) curve, are introduced to assess the impact of the carbon dioxide emission on the generation cost. Incorporating with the aforementioned index, the single-objective and bi-objective programming methods are employed to establish the power dispatching strategy. The salient feature of the dispatching strategy lies that the decision-maker can consider the environmental and economic factors at the same time. Since the power dispatching belongs to large-scale non-linear planning problem, this study employs a particle swarm approach with novel coding scheme for power dispatch solution, which can fast find an optimal solution with higher probability. Finally, taking the 27-unit system of the Tai-power as an example, simulation result of the study reveals that the proposed dispatching strategy can indeed consider the carbon dioxide reduction impact on cost in off-peak, half-peak and peak load conditions to achieve environmental protection and economic purpose.
