摘要

台灣近年來大力推動風力發電等再生能源的發展，並將在澎湖等離島地區設置多部風力機組。然而由於風力發電輸出的不穩定性，當風力機出力佔比較高時，將對系統電壓、頻率和供電可靠度造成影響，進而影響澎湖電力系統之電網規劃以及運轉，故對於澎湖電力系統承受多少容量的風力發電，才不致造成系統安全運轉問題，是一項非常重要的議題。為此，本研究以IEC 61400-21規範評估風機併網之電力品質為依據，並依線路容量、電力品質、可靠度、運轉頻率限制及斷路器遮斷容量限制等五項評估準則，利用PSS/E電力系統模擬軟體，針對澎湖地區從民國96年至民國101年間，台澎海底電纜尚未興建之前，提出風機佔比允許上限之評估步驟，以不同時期的發電及負載運轉模式為基礎，藉系統指標饋線評估事故後之電壓、頻率與機組反應特性，來評估最大風力發電佔比。

Taiwan lend an impetus to develop renewable energy in recent year, such as wind power generation, and TPC is planning to install a large amount of wind generators at offshore island Penghu. However it may affect power quality and reliability of Penghu Power System due to wind generation variability, and influence the planning and operation of Penghu power system with high wind penetration . How many wind generation penetration allowed is an important issue since the system security is highly concerned. This research based on IEC 61400-21 standard to determine the power quality when wind turbines connection to power system, based on transmission capacity, power quality , the limited frequency and the breaker capacity, focuses on the years range from 2007 to 2012 that before constructing the submarine cable connecting between Penghu island and Taiwan, simulates the power system contingencies based on generation and load operation pattern in different periods by adopting the power system simulation program PSS/E. This research considers the index feeder post fault power quality in distribution system by the voltage, frequency and generator response characteristic from system disturbance, and to determine the maximum allowed wind penetration in Penghu island.
