可再生能源绿证价格季节性测算方法研究

  目的  在市场化交易模式消纳可再生能源发电的发展趋势下，“市场电价+绿证收入”将成为未来可再生能源发电企业的主要经营模式。以可再生能源发电参与现货电能量市场为研究大背景，对可再生能源绿色电力证书的价格进行研究。  方法  基于现货电能量市场的优化出清模型，应用可再生能源全生命周期成本测算理论，以满足可再生能源发电企业的内部收益为目的，建立了绿证-电能量市场耦合的优化模型，并结合可再生能源季节性出力特性，提出了可再生能源绿证价格季节性曲线及其波动区间的仿真和测算方法。  结果  不同类型的可再生能源绿证价格不同，不同类型的可再生能源绿证价格的气候相关性亦不相同。  结论  绿证价格的科学合理测算不仅可以帮助可再生能源发电企业进行收益评估和制定更为准确的投资决策，还为电力市场主体与交易中心提供相关决策支持。

Research on Seasonal Calculation Method of Renewable Energy Certificate Price

［Introduction］ Based on the trend of consuming renewable energy sources （RES） through the market-based trading model， the “market electricity price + renewable energy certificate （REC） revenue” will become the main operation of energy generators in the future. Based on the research background of RES participating in spot power market， this paper studies the price of REC.  Method  Based on the optimized clearing model of the spot electric energy market， applying the theory of the life cycle costing （LCC） of RES generation and satisfying the internal rate of return （IRR） of the energy generators， we established the optimization model of coupling REC-electric energy market. Combined with the seasonal output characteristics of RES， the simulation and measurement methods of the seasonal curve and fluctuation interval of REC price are proposed.  Result  The price of REC for different types of RES are different， and the price of REC for different types of RES also has different climatic correlations.  Conclusion  Scientific and reasonable calculation of REC price can not only help RES generation enterprises make income assessment and more accurate investment decisions， but also provide relevant decision-making support for power market entities and trading centers.
