摘要

在高渗透水平下，额外兆瓦风的边际平均弃风率通常是其平均弃风率的3倍以上。对于陆上和海上风能和太阳能光伏的投资组合，这一比例要高得多。随着使用潜在剩余VRE（出口、储存）方法的增加，平均弃风率下降，但边际平均弃风率上升。VRE的边际平化成本与边际容量系数成反比，边际容量系数随着边际弃风量的增加而下降，这引起了人们的担忧，即减少平均弃风量可能不会降低VRE的边际成本。本文证明情况并非如此。减少弃风对边际弃风的影响被放大，并且确实降低了VRE的边际成本。

Implications of renewable electricity curtailment for delivered costs

At high penetration levels, the ratio of the marginal: average curtailment of an extra MW of wind is typically 3+ times its average. For a portfolio of on- and off-shore wind and solar PV, the ratio is considerably higher. With increasing methods of using potentially surplus VRE (exports, storage) average curtailment falls but the ratio of the marginal: average curtailment rises. The marginal levelised cost of VRE is inversely proportional to the Marginal Capacity Factor, which falls as marginal curtailment increases, raising concerns that reducing average curtailment may not lower the marginal cost of VRE. This paper proves this is not the case. Reducing curtailment has a magnified effect on marginal curtailment and does indeed lower the marginal cost of VRE.

期刊介绍： Energy Economics is a field journal that focuses on energy economics and energy finance. It covers various themes including the exploitation, conversion, and use of energy, markets for energy commodities and derivatives, regulation and taxation, forecasting, environment and climate, international trade, development, and monetary policy. The journal welcomes contributions that utilize diverse methods such as experiments, surveys, econometrics, decomposition, simulation models, equilibrium models, optimization models, and analytical models. It publishes a combination of papers employing different methods to explore a wide range of topics. The journal's replication policy encourages the submission of replication studies, wherein researchers reproduce and extend the key results of original studies while explaining any differences. Energy Economics is indexed and abstracted in several databases including Environmental Abstracts, Fuel and Energy Abstracts, Social Sciences Citation Index, GEOBASE, Social & Behavioral Sciences, Journal of Economic Literature, INSPEC, and more.
