风力发电的平均市场价值可能低于其他发电技术，这是投资风力发电的一个经济障碍。这是由其他发电商行使市场支配力以及这些发电商行使市场支配力的能力与实时风力可用性成反比的事实驱动的。我们研究了利用储能来缓解这种价格抑制，将风力发电从低价格时期转移到高价格时期。我们表明，存储可以显着增加风力发电的价值，但目前的高资本成本的存储技术不能证明这种使用的基础上。此外，我们证明了这种使用存储可以减少消费者剩余，其他非风力发电机的利润和社会福利。我们还研究了这些影响的敏感性，一些参数，包括存储大小，存储效率，所有权结构，和市场竞争力表明，一个更具竞争力的市场可以使存储更有价值的风力发电机。
Abstract One economic disincentive to investing in wind generation is that the average market value of wind energy can be lower than that of other generation technologies. This is driven by the exercise of market power by other generators and the fact that the ability of these generators to exercise market power is inversely related to real-time wind availability. We examine the use of energy storage to mitigate this price suppression by shifting wind generation from periods with low prices to periods with higher prices. We show that storage can significantly increase the value of wind generation but the currently high capital cost of storage technologies cannot be justified on the basis of this use. Moreover, we demonstrate that this use of storage can reduce consumer surplus, the profits of other non-wind generators, and social welfare. We also examine the sensitivity of these effects to a number of parameters including storage size, storage efficiency, ownership structure, and market competitiveness—showing that a more-competitive market can make storage significantly more valuable to a wind generator.
