再生能源發電高滲透率之配電饋線分析－對再生能源發電系統併聯技術要點之檢討
Analysis of distribution feeders with high penetration of renewable energy resources
摘要
台灣因為屬於海島地形，天然資源不足，政府因應環境變化與全球趨勢，投入大量資金與人才研發及提升我國再生能源相關發展，期望能減少對外國進口的石化燃料依賴性。政府為推廣太陽能發電及風力發電兩項再生能源系統；經濟部於民國98年7月8日公布「再生能源發展條例」、子條例與相關規範，作為台灣各地區發展再生能源之標準。 在各項措施與輔助政策的環境中，台灣的太陽能以及風力發電滲透率(penetration)年年升高，但「再生能源發展條例」以及相關條例所規範之要點，是否能夠符合現今台灣再生能源發電環境？面對日漸成長的再生能源發電之大型躉售電力併聯於配電系統，能否在已發佈條例下運作而並不影響配電之電力品質？值得探討。本論文使用EPRI開放式配電系統模擬軟體OpenDSS，依「台灣電力股份有限公司再生能源發電系統併聯技術要點」之規範條例，進行太陽能及風力發電對配電系統電壓變動率的模擬分析。由模擬結果得知，若配電系統併聯規範所容許之最大太陽能及風力發電系統容量，有可能導致電壓變動率超過規範所要求的小於±2.5%。

Taiwan is an island which have very limited natural resources. In order to reduce the dependence on imported fossil fuel, Taiwan government began to invest a lot of money and manpower in renewable energy technologies. The Renewable Energy Development Act of Taiwan is published in July 8, 2009. Solar and wind power systems are highly promoted in Taiwan since then, but the Act has no amendment since it announced. The growth of renewable energy generation capacity will increase the affection of the power quality of distribution system. In this thesis, OpenDSS developed by EPRI is used to simulate the voltage profile for maximum allowable renewable energy power input of the distribution feeder. The results show that if the sum of renewable power generations is greater than demand, the voltage alone the feeder could be greater than 2.5%, which does not comply with the voltage regulation in Taipower’s document: The Regulation of Renewable Energy Generation System Connected to Grid.
