Evolving Energy Systems Through Innovations in Energy Storage

能源系统正在演变。随着电网架构的变化和间歇式可再生发电机普及率的持续增长，能源系统的灵活性变得越来越重要。存储已被确定为这种灵活性的关键组成部分，因为它从技术和市场两个角度帮助协调供需之间的失衡。ES的好处可以包括改善可再生能源整合的条件，减少化石燃料发电厂，改善电力质量和可靠性，推迟系统升级成本，以及改善电力机动性。对于所有这些好处，新的ES技术的成功商业化可能是困难的。许多ES技术的广泛商业实现面临着一些挑战。首先是对存储可以为利益相关者提供的所有有益服务进行适当的估值。这不仅取决于服务的市场，还取决于存储资产提供这些服务的能力。因此，存储价值主张的准确性不仅受特定市场知识的影响，还受资产表现真实细节的影响。

Energy systems are evolving. Energy system flexibility is becoming increasingly important as grid architectures change and the penetration of intermittent renewable generators continue to grow. Storage has been identified as a critical component of such flexibility by helping to reconcile imbalances between supply and demand from both technical and market perspectives. Benefits of ES can include improved conditions for renewables integration, a reduction of fossil fuel peaker plants, improved power quality and reliability, deferral of system upgrade costs, and improved power maneuverability. For all of these benefits, successful commercialization of new ES technologies can be difficult. A few challenges face the broad commercial realization of many ES technologies. The first is a proper valuation of all the beneficial services storage can provide to stakeholders. This depends on the market for the services, but also, the ability of the storage asset to provide those services. Thus accuracy of storage value propositions is affected by specific market knowledge, but also the true details of asset performance.
