摘要

电力部门的转型是向脱碳经济过渡的核心要素。化石燃料驱动的传统发电机必须由可变可再生能源(VRE)替代,并结合电力储存和其他提供时间灵活性的选择。我们讨论了增加VRE渗透的市场动态及其在电力系统中的整合。我们描述了优序效应(VRE渗透率增加时批发电价下降)和同类相食效应(VRE值随着渗透率增加而下降)。我们进一步审查了电力存储和其他灵活选择在整合可变可再生能源方面的作用,以及存储如何有助于减轻上述两种影响。我们还使用了一个程式化的开源模型来提供关于这些问题的一些图形直观。虽然通过适度的电力储存可以实现相对较高的可再生能源份额,但随着可再生能源份额接近100%,长时间储存的作用会增加。

The Economics of Variable Renewable Energy and Electricity Storage
The transformation of the electricity sector is a central element of the transition to a decarbonized economy. Conventional generators powered by fossil fuels have to be replaced by variable renewable energy (VRE) sources in combination with electricity storage and other options for providing temporal flexibility. We discuss the market dynamics of increasing VRE penetration and its integration in the electricity system. We describe the merit-order effect (the decline of wholesale electricity prices as VRE penetration increases) and the cannibalization effect (the decline of VRE value as its penetration increases). We further review the role of electricity storage and other flexibility options for integrating variable renewables and how storage can contribute to mitigating the two mentioned effects. We also use a stylized open-source model to provide some graphical intuition on these issues. While relatively high shares of VRE are achievable with moderate amounts of electricity storage, the role of long-duration storage increases as the VRE share approaches 100%.
