英文摘要 | Taiwan has an independent electric grid that cannot be connected with those of other countries. This power system is isolated; thus, overseas assistance cannot be relied on during power shortages. Therefore, power development and advanced dispatch planning are crucial. This study uses multi-objective planning to construct a power supply planning model for the island of Taiwan. With the goals of minimizing power generation costs and CO emissions, this study simulated past power supply and dispatch situations, verified the feasibility of these simulations, and subsequently simulated power dispatch situations in set scenarios for the future target year to evaluate the benefits of CO emissions reduction. Focusing on the policies of retrofitted power plants, increases in natural gas usage, commercial operations or no commercial operation of Taiwan's fourth nuclear power plant, punctual decommissioning of nuclear plants, cogeneration, and expansion of the renewable energy installed capacity, this study explored the influence the power supply model on the supply and dispatch of power, power generation costs, and CO emissions when implementing related policies. The scenario simulation results show that regardless of whether all carbon reduction techniques mentioned in the study scenario are conducted, the total amount of CO emissions will still increase from 122.6 Mt in 2010 to 141.6 Mt in 2030. A 51.6 Mt disparity with the 90 Mt reduction target established in 2000 exists. Although carbon emissions show a declining trend overall (0.634, 0.565, 0.536 kg CO kWh-1 in 2010, 2020, 2030, respectively), emissions will increase from 2018 to 2025 because of the decommissioning of Taiwan's first, second, and third nuclear power plants beginning in 2018, and their replacement with coal-fired units to meet power demands. If all carbon reduction techniques included in the study scenario are conducted, power generation costs are anticipated to increase from-12.108 to 2.452 NT kWh , a rise of 7.74%, because of higher fuel costs. If the 4th nuclear power plant is not commercially operated, the cost of electricity will increase from 2.108 to 2.454 NT kWh-1 , about 7.79% higher. |
