摘要
近年環保意識抬頭,能源議題須具環保觀念,潔淨的再生能源成為各國政府致力發展及推廣的方向,隨著未來間歇性再生能源(如風力、太陽光電)佔比的提升,其不穩定及不易預測等特性,對電力系統併網及運轉將造成供電品質及可靠度的衝擊,若未具備所需配套因應對策,日後非預期的停/限電次數及時間恐將增加,將對國家整體經濟發展帶來威脅。目前政府推行再生能源發電主要以太陽光電及風力發電為主,鑒於不穩定之再生能源是否優先併網發電,其對系統運轉及產業的衝擊是否會如同歐盟傳統電業於五年內,資產市值少了一半,在重大能源政策拍板前,宜通盤思考;本文針對先進國家大力發展再生能源時曾經歷的問題,檢視再生能源併網運轉經驗,探討政府欲擴大推動再生能源時,技術面所需配套,如再生能源設備之性能要求及於電力系統擾動時所須具備的電壓及頻率承載能力,以確保電力品質及供電可靠度。本文期盼藉由吸取先進國家運轉經驗,作為國內未來對再生能源併網運轉所需配套及相關規範訂定的參考,供相關決策者於規劃能源政策時,能注意到技術面的障礙,以縮短臺灣學習的時間與減少盲目投資造成的浪費。

Growing environmental awareness has led to increased attention toward energy sources in recent years, and governments worldwide are developing renewable energy. Renewable energy are characterized by their intermittent and unpredictable nature; with increasing penetration of renewable energy, these characteristics increasingly undermine the reliability and quality of the electricity supply from these sources. If adequate countermeasures are not developed, the number of unexpected outages and brownouts will increase in the future, which is a threat to the economy of any country. Taiwan’s primary renewable energy policy currently focuses on the development of photovoltaic and wind energy. Before deciding major energy policies, the government should consider the effect of interconnection of renewable energy power system and the power industry. For example, shares of traditional European electrical utilities have plunged 50% in five years because of the increasing penetration of renewable energy. This paper examines foreign experiences with interconnection of renewable energy and discusses the technical support needed for developing renewable energy. Such as, performance requirements of equipment for renewable energy, and when the power system is incurred disturbance, they must have voltage and frequency ride-through capacities to ensure power quality and power reliability. The experience of interconnection of renewable energy in countries with advanced renewable energy systems can be a reference for future policy decisions in Taiwan. This paper is expected to serve as reference for policy makers when planning energy policy for Taiwan. That can shorten the learning time and reduce waste caused by blind investment.
