摘要:

极端高温下,新型电力系统降温负荷急增、输电设备故障率升高,系统难以安全可靠运行。为提升新型电力系统抵御极端高温的能力,考虑重要负荷对系统韧性的影响,提出基于差异化规划的韧性提升方案。首先,建立高温下系统负荷与线路故障率之间的关系模型,对脆弱线路进行识别。其次,为避免因未考虑重要负荷而使评估产生“遮蔽”现象,提出一种考虑负荷分级的韧性评估方法。然后,考虑到故障的不确定性,基于差异化规划,以运行成本与负荷损失最小为目标建立针对脆弱线路和储能的两阶段鲁棒优化模型,并采用列与约束生成(C&CG)算法进行求解,得到最优规划方案。最后,通过算例验证了该方案的有效性。

Abstract:

Under extreme high temperature, the cooling load of new power systems increases rapidly and the failure rate of transmission equipment increases, which makes it difficult to operate safely and reliably. To enhance the resilience of the new power system against such extreme high temperature, a differentiated planning based resilience enhancement scheme is proposed by taking into account the impact of critical loads on system resilience. Firstly, a relationship model between system load and line failure rates under high temperature is established to identify vulnerable lines. Secondly, to avoid the “overshadowing” phenomenon caused by neglecting critical loads in the assessment, a resilience assessment method that considers load classification is proposed. Then, considering the uncertainty of failures, based on differentiated planning, a two-stage robust optimization model for vulnerable lines and energy storage is established with the objective of minimizing operation costs and load losses. The column-and-constraint generation (C&CG) algorithm is also used to solve and obtain the optimal planning scheme. Finally, the effectiveness of the scheme is validated through numerical cases.
