摘要
2016年6月我國能源局頒布修正再生能源推廣目標,2025年總體再生能源裝置容量將達27,423 MW,未來電力系統之再生能源占比將大幅提升。由於再生能源的間歇特性,將對電力系統運轉造成供電品質及可靠度的衝擊,隨著具備先進電力電子設備之大量非線性電源及負載加入,諧波對系統的影響將日漸明顯,另外高占比再生能源出力變動影響系統慣性的頻率響應,亦將改變電力系統的保護協調設定。若未具備因應高占比再生能源之所需配套與對策,日後非預期的停/限電次數及時間恐將增加,將對國家整體發展帶來威脅。本文章提出未來再生能源併網對臺灣電網衝擊的可能影響因素,了解高占比再生能源對我國電力系統的衝擊影響,提供後續政策推動與研究之參考方向,期我國未來的能源政策能順利推動。

In 2016 June, the revised version for renewable energy target was released by Bureau of Energy, which mean that the total renewable energy target capacity will achieve 27,423 MW in 2025, and that the penetration of renewable energy in power system will be raised in the future. The power quality and reliability in power system will be affected by renewable energy because of its intermittent characteristic. The harmonic effect in power system is significantly grow as more and more non-linear power sources and loads are used. Owing to the variety of system inertia and renewable energy output, the relays in grid need to be rearranged in the future. There will be more power failures and the problems in economic development if there is no measures prepared by government. To help carry out energy policy successfully, the influence of renewable energy on power system will be talked about in this paper. The suggestions for carring out policy and study will also be presented.
