论文摘要

区域电力系统之间的领带电力交换有助于可再生住宿。可以通过平局安全区域来计算功率交换,该区域提供区域电力系统之间耦合参数的可行区域。但是,由于多个时间段内和电力系统操作中的边界总线,领带的安全区域是高维度的高维度,导致了相当大的计算负担。本文研究了针对高维度中的领带安全区域的快速计算方法。在所有时间段内,高维度均分解为笛卡尔在每个时间段内的笛卡尔生产,通过利用几代人的调度水平。对于每个较低维度的多层,由多个边境公共汽车带来的计算负担可以通过汇总的平线功率来减轻。此外,通过在领带安全区域中纳入一个额外的维度来保留最低可再生能源的削减。对于位于我们的领带安全区域内的耦合参数,存在区域电力系统的可行决定。最后,领带安全区域用于减少在分散和非文字框架下相互联系的电力系统中的可再生能力减少。在IEEE 9-BUS系统,661-Bus实用程序系统和五个区域系统中,介绍的方法的性能得到了证实。

Tie-line power exchanges among regional power systems facilitate renewable accommodations. Power exchanges can be calculated via a tie-line security region that provides the feasible region of the coupling parameters among regional power systems. However, a tie-line security region is a high-dimension polytope due to multiple time periods and border buses inherently in power system operations, leading to the considerable computational burden. A fast calculation method for tie-line security regions in high dimension is studied in this paper. The high-dimension polytope across all the time periods is decomposed as a Cartesian production of lower-dimension polytopes at each time period by leveraging dispatch levels of generations. For each lower-dimension polytope, the computational burden brought by multiple border buses is alleviated by aggregating tie-line power. Also, minimum renewable curtailments are preserved by incorporating an additional dimension in the tie-line security region. For the coupling parameters located within our tie-line security region, a feasible decision of the regional power system exists. Finally, the tie-line security region is used to reduce renewable curtailments in an interconnected power system under a decentralized and non-iterative framework. The performance of the presented methods is corroborated in the IEEE 9-bus system, a 661-bus utility system and a five-region system.
