摘要
本文旨在探討臺灣綠能導向之電力市場發展策略及其配套措施。首先,描述再生能源全球發展趨勢及其特性之優缺點,提出太陽能及風力發電間歇性問題,然而藉由結合多元利害關係人及智慧科技應用,反而潛藏著更高的創新價值。當臺灣再生能源發電比例逐年提高,面對此一結構性之典範移轉,建構電力市場機制極為重要。其次,藉美國加州負載曲線變化的案例,說明何謂鴨子曲線及其影響,同時分析臺灣出現鴨子曲線的可能性,並論述德國、加州及德州出現負電價的經濟意涵。接著,面對再生能源大量併入電網可能帶來的衝擊,本文提出「導入公平競爭的市場機制」作為因應對策,亦即藉由電力市場的價格訊號提供合理誘因,增加利害關係人的多元性及來源,方具 電力市場的彈性與韌性。再者,本文參酌美國聯邦能源管制委員會之規範架構,分述能量市場、容量市場以及輔助服務市場之功能與角色定位,並參考台電公司已規劃之電力交易平臺機制,提出相關建言。最後,本文主張政府有關單位應積極導入綠電市場競爭機制,尤其電力系統操作者與電力市場操作者必須緊密同歩配合,建構健全之電力市場新生態系統經濟,同時讓臺灣科技與產業發展加速邁向綠能永續的境地。

This paper aims to explore Taiwan's green energy-oriented power market development strategies and related measures. First, the paper describes the global development of renewable energy with its advantages and disadvantages. The intermittence of solar and wind power generation must corporate with diverse stakeholders to create higher value with smart technology applications. As the proportion of renewable energy in Taiwan increases year by year, it is extremely important to build a power market mechanism to face this structural paradigm shift. Second, this paper uses the variation of the load curve in California as the case to explain what is the “duck curve” and its impact, then analyzes the possibility of the duck curve happening in Taiwan. This paper also discusses the economic implications of negative electricity prices in Germany, California, and Texas. Third, facing the potential impact of high renewable energy generation-mix integrated into the power grid, this paper proposes a fair-trade market mechanism for all stakeholders as a countermeasure. That is, the relevant policy has to provide timely price signals with sufficient incentives to attract more stakeholders to stipulate ancillary service, to keep the flexibility and resilience of the electric power market. Furthermore, referring to the regulatory framework of the US Federal Energy Regulatory Commission, this paper elaborates on the functions and role of the energy market, capacity market, and ancillary service market, and provides some suggestions based on the power trading platform mechanism that Taipower company has planned. Finally, this paper argues that the Taiwan government should actively introduce the fair and competitive mechanism of the green power market. In particular, power system operators and power market operators must work closely with each other to build a sound and new ecosystem in the power market, leading to the sustainable development of Taiwan's industry and economy as a whole.
