摘要

长时间储能（LDES）装置尚未广泛安装在现有的电力系统中，但有望在高可变可再生能源电网中发挥重要作用。LDES器件的选址是复杂的，并且会显著影响系统成本，但影响最佳LDES器件放置的因素尚未完全了解。我们考虑了LDES器件在两种具有不同系统配置的不同电源系统中的最佳位置。我们使用生产成本模型分析了VRE的集中和位置、负载位置、其他存储设备位置和传输可用性的影响。我们发现，所有这些因素都会影响LDES的最佳选址，没有一个单一的指标能够始终如一地确定最佳选址。此外，我们发现LDES在电网中的放置会对整个电网产生影响（例如，在某些地区增加削减，而在其他地区减少削减），我们提出了未来工作的几个领域。

Toward understanding the complexity of long-duration energy storage siting in high renewable power grids

Long-duration energy storage (LDES) devices are not yet widely installed in existing power systems but are expected to play a significant role in high variable-renewable energy grids. Siting LDES devices is complex and can significantly impact system cost, but the factors influencing optimal LDES device placement are not fully understood. We consider the optimal placement of an LDES device in two different power systems with varied system configurations. We analyze the impact of VRE concentration and location, load location, other storage device locations, and transmission availability using production cost models. We find that all of these factors influence optimal LDES siting, and no single metric considered was able to consistently identify optimal placement. Further, we found that LDES placement in the grid can have impacts that propagate throughout the grid (e.g., increasing curtailment in certain areas while decreasing it in others), and we propose several areas of future work.

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
