论文摘要
可再生能源（RES）最近引起了很多兴趣。有限的传输容量服务通常会导致网络拥塞，因为它们位于偏远的有利位置。结果，当安排不当的情况下，RES的间歇性可能会导致自由资源的高度削减。当前，网格操作员在执行日前计划时会使用静态网络并忽略传输灵活性。本文探讨了利用网络重新配置作为减少传输拥塞的纠正措施的可能性，从而减少了日期安排中的RES减少。为了促进网格中的RES集成，建模了具有纠正网络重新配置（SSCUC-CNR）的随机N-1安全受限的单位承担。 SSCUC-CNR模型在带有RES的修改的IEEE 24总线系统上进行了研究。仿真结果表明，CNR不仅通过减少网络拥塞来导致较低的成本解决方案，而且还通过减少高渗透案件中拥塞诱导的缩减来促进RES集成。排放研究表明，实施CNR时，更多的绿色发生器会导致碳排放量减少。
Renewable energy sources (RES) has gained a lot of interest recently. The limited transmission capacity serving RES often leads to network congestion since they are located in remote favorable locations. As a result, when poorly scheduled, the intermittent nature of RES may result in high curtailments of the free resource. Currently, grid operators utilize a static network when performing day-ahead scheduling and ignore transmission flexibility. This paper explores the possibility of utilizing network reconfiguration as a corrective action to reduce the transmission congestion and thereby the reduction of RES curtailments in day-ahead scheduling. To facilitate the RES integration in the grid, a stochastic N-1 security-constrained unit-commitment with corrective network reconfiguration (SSCUC-CNR) is modelled. SSCUC-CNR model is studied on a modified IEEE 24-bus system with RES. The simulation results demonstrate that CNR not only leads to a lower cost solution by reducing network congestion but also facilitates RES integration by reducing congestion-induced curtailments in high penetration cases. Emission studies demonstrate that more green generators are committed resulting in reduced carbon emissions when CNR is implemented.
