摘要
本研究運用混合整數線性規劃方法論建置金門地區電力系統整合資源規劃模型,並以最小電力 系統營運成本目標分析基準情境、政策減碳情境及深度減碳情境之電力供需規劃。基準情境發展至 2030年時,電力系統主要電力供應為燃油機組(約占88%),再生能源供電占比約9%,電力碳排放係 數0.633公斤/度,屬於高度碳排放的電力供應組合。金門地區若要以最小營運成本達成政策減碳目 標,建議2030年前至少須增建8.66 MW陸域風力、85.84 MW太陽光電及4 MW/16 MWh儲能系統。 政策減碳情境將使金門地區2030年再生能源供電占比將達44.72%;電力成本相對2020年將會增加約 17%;當年尖峰負載發生日約可維持約4個小時100%再生能源供電。深度減碳情境分析再生能源供 電占比分別達50%、60%、70%及80%時,對電力碳排放的影響及再生能源與儲能系統的需求量。 若要提升金門地區2030年再生能源供電占比達80%,建議2030年前至少須增建170 MW再生能源(150 MW太陽光電 + 20 MW陸域風力)及93 MW/372 MWh儲能系統,約有22.54%的再生能源須倚靠儲能 系統進行供電。深度減碳情境將使2030年電力碳排放係數降至0.137公斤/度,相對基準情境約減少 83%;相對政策減碳情境約減少63%,當年尖峰負載發生日約可維持約14小時100%再生能源供電。

This research employed linear programming methodology to establish an integrated resource planning model for power system in Kinmen, and analyzes Reference, Policy Decarbonization and Deep Decarbonization scenarios with the minimum power system operating cost objective. The main power supply of the power system is fuel-fired power (about 88%), renewable energy power supply accounts for about 9% and the power carbon emission coefficient is 0.633 kg/kWh for Reference Scenario in 2030. This scenario belongs to the power supply portfolio with high carbon emissions. In suppose to achieve the policy decarbonization target at the minimum cost in Kinmen, it is recommended that at least 8.66 MW of onshore wind power, 85.84 MW of PV and 4 MW/16 MWh of energy storage system be built before 2030. The Policy Decarbonization Scenario will increase renewable energy power supply in Kinmen to 44.72% of electricity demand in 2030; power cost will increase by about 17% compared with 2020. Power system can maintain 100% renewable energy supply for about four hours in peak day in 2030. Deep Decarbonization scenario analyzes the impact on power carbon emissions and capacity demand for renewable energy and energy storage system when renewable energy power supply reaches 50%, 60%, 70% and 80%, respectively. In suppose to increase renewable energy power supply in Kinmen to 80% in 2030, it is recommended that at least 170 MW of renewable energy (150 MW PV + 20 MW onshore wind) and 93 MW/372 MWh energy storage system be built before 2030, and 28% of the renewable energy generation relies on energy storage system for power supply. Deep Decarbonization scenario will reduce the power carbon emission coefficient to 0.137 kg/kWh in 2030, which are about 83% and 63% less than Reference scenario and Policy Decarbonization scenario, respectively. Deep Decarbonization scenario can maintain 100% Renewable energy supply for about 14 hours in peak day.
