摘要

大部份的國家為了支持及推動再生能源，制定了許多不同的再生能源推動機制，這些機制可能會對電力部門產生影響，如提高發電成本。
    因此，本研究建構系統動態模型，以評估再生能源機制的推動對發電成本、二氧化碳排放量及環境外部成本之影響。本模型的再生能源推
   動機制的情境假設分別為固定電價收購機制（fixed feed-in tariff, FIT ）、固定電量收購機制（renewable portfolio standard, RPS）。透
  過本模型分析所得之結果，採行FIT機制之環境保護效果優於RPS機制。

英文摘要

In order to support electricity generation from renewable energy, most countries have instituted different mechanisms which may place 
impacts on the electricity sector. The purpose of this study is to establish a system dynamics model of electricity supply structure to evaluate
the impacts on power cost, CO2 emission and environmental external cost. The scenarios are both fixed feed-in tariff and renewable portfolio 
standard mechanisms. The results show that increases in renewable energy supply will drive rises in power generation cost, and compared 
with the renewable portfolio standard, the fixed feed-in tariff mechanism has better effects on environment protection.
