电力系统小时内不平衡预测
Forecasting Intra-Hour Imbalances in Electric Power Systems
摘要：
保持电力生产与实际需求的平衡正在成为一项困难和昂贵的任务，尽管有经验的人类操作员的参与。这是由于电网系统日益复杂，间歇性可再生能源生产是其中一个贡献者。关于发生的不平衡的预先信息可以帮助传输系统操作者调整生产计划，并且因此通过减少昂贵的平衡储备的使用来确保供电的高安全性，并且因此减少50Hz电力系统频率的不期望的波动。在本文中，我们介绍了一个相对较新的问题，一个小时内的不平衡预测的传输系统运营商（TSO）。我们专注于挪威TSO Statnett的用例。我们提出了一个互补的不平衡预测工具，能够支持TSO确定未来不平衡的趋势，并显示出与当代解决方案相比具有更高准确性的主动缓解不平衡的潜力。
英文摘要：
Keeping the electricity production in balance with the actual demand is becoming a difficult and expensive task in spite of an involvement of experienced human operators. This is due to the increasing complexity of the electric power grid system with the intermittent renewable production as one of the contributors. A beforehand information about an occurring imbalance can help the transmission system operator to adjust the production plans, and thus ensure a high security of supply by reducing the use of costly balancing reserves, and consequently reduce undesirable fluctuations of the 50 Hz power system frequency. In this paper, we introduce the relatively new problem of an intra-hour imbalance forecasting for the transmission system operator (TSO). We focus on the use case of the Norwegian TSO, Statnett. We present a complementary imbalance forecasting tool that is able to support the TSO in determining the trend of future imbalances, and show the potential to proactively alleviate imbalances with a higher accuracy compared to the contemporary solution.
