Abstract: 政府為實現非核家園目標,正逐步推動能源轉型政策,預定在2025年達成將再生能源發電占比提升至百分之二十、天然氣發電占比提升至百分之五十、以及燃煤發電占比降低至百分之三十之能源轉型目標。目前政府能源政策使得發電能源占比產生劇烈改變,直接影響了傳統的機組維修排程與發電機組排程,也衝擊了台電公司行之多年的經濟調度模式。
2017年夏季期間,和平電廠電源線(冬山-和平兩回線)因尼莎颱風造成#72鐵塔倒塌,對台灣整體電力系統之電力調度造成極大影響。本論文針對2018年~2026年期間台灣地區電力系統各種假設情境,運用PSS/E軟體進行年尖峰負載日之電力潮流分析與345kV輸電線路N-2事故之模擬,藉以分析其對台灣整體電力系統所造成之衝擊影響。本研究各項評估結果與建議可作為台電公司在電力調度與電網規劃方面之參考,亦可作為政府在發電能源政策方面的決策參考。
In order to achieve the goal of nuclear-free homeland, the government is gradually promoting energy transformation policies. It is scheduled in energy conversion goals to increase the proportion of renewable energy power generation to 20%, increase the proportion of natural gas power generation to 50%, and decrease the proportion of coal-fired power generation to 30% in 2025. At present, the government's energy policy has caused a dramatic change in the proportion of power generation, directly affecting the traditional unit maintenance schedule and generator set scheduling, and also impacted the economic dispatch mode which has been run many years in TPC. During the summer of 2017, the power line of the Peace Power Plant (Dongshan-Peace Double Line) caused the collapse of #72 Tower caused by Typhoon Nishsa, which greatly affected the overall power dispatch in Taiwan power system. This thesis focus on the power flow analysis of the annual peak load day and N-2 contingency on 345kV transmission line using the PSS/E software for various hypothetical scenarios of the power system in Taiwan during the period from 2018 to 2026, in order to analyze its impact effect on Taiwan power system. The evaluation results and recommendations of this study can be used as reference for the Taiwan power company in power dispatching and power grid planning, and can also be used as a reference for government decision-making in power generation energy policy.
