High Taxes on Cloudy Days: Dynamic State-Induced Price Components in Power Markets
研究了将电力市场中国家诱导的固定价格成分改为随时间变化，对整合可变可再生能源和脱碳的好处，基于德国85%可再生能源系统的模型分析，发现动态化可降低可再生能源整合成本0.3至3.4欧元/兆瓦时，并有利于灵活消费者。
State-induced components constitute the major share of electricity prices for consumers and are generally charged at a fixed rate. We analyze the benefits of charging state-induced price components at time-varying rates instead, especially with regard to the integration of variable renewable energy (VRE) sources and to decarbonization. For this purpose, we apply a detailed power market model that puts particular emphasis on electricity demand and how it is sensitive to prices.For a quantitative case study, the model is parametrized to represent a German energy system with an 85% share of renewables in its power generation. We find that dynamization has a reducing effect on integration costs of VRE, ranging from 0.3 to 3.4 €/MWh. Furthermore, strong distributional effects in favor of flexible consumers can be observed.
