论文摘要
正在计划针对世界上多个电网的大规模可再生能源整合。为了实现安全稳定的网格操作,需要其他资源/储备金来减轻可再生能源(RES)的固有间歇性。在本文中,我们介绍了制剂,以了解快速存储储量在不同成本功能下提高网格可靠性方面的影响。我们的配方和解决方案方案不仅旨在最大程度地减少失衡,而且还旨在保持最先进的存储(SOC)。特别是,我们表明,由于惯性和地方调节响应而导致的系统响应,可以更逼真地量化存储要求,以减阻净负荷波动。存储需求明显低于当不考虑这种传统响应时确定的值。我们通过使用比利时Elia TSO和美国BPA代理商的Elia TSO的实际数据进行研究来证明我们设计的政策的性能。数值结果使我们能够基于在不同的系统响应和相关成本功能下增加存储量而对可靠性产生边际影响。
Large scale renewable energy integration is being planned for multiple power grids around the world. To achieve secure and stable grid operations, additional resources/reserves are needed to mitigate the inherent intermittency of renewable energy sources (RES). In this paper, we present formulations to understand the effect of fast storage reserves in improving grid reliability under different cost functions. Our formulations and solution schemes not only aim to minimize imbalance but also maintain state-of-charge (SoC) of storage. In particular, we show that accounting for system response due to inertia and local governor response enables a more realistic quantification of storage requirements for damping net load fluctuations. The storage requirement is significantly lower than values determined when such traditional response are not accounted for. We demonstrate the performance of our designed policies through studies using real data from the Elia TSO in Belgium and BPA agency in the USA. The numerical results enable us to benchmark the marginal effect on reliability due to increasing storage size under different system responses and associated cost functions.
