Abstract

In this paper, we propose a two-stage transmission hardening and planning (TH&P) model that can meet the load growth demand of normal scenarios and the resilience requirements of hurricane-induced damage scenarios. To better measure the resilience requirements, the proposed TH&P model includes two resilience assessment indexes, namely, the load shedding (LS) under the damage scenario and the average connectivity degree (ACD) at different stages. The first-stage model, which aims to meet the load growth demand while minimizing the LS, is formulated as a mixed-integer linear program (MILP) to minimize the total planning and hardening cost of transmission lines, the operating cost of generators, and the penalty cost of wind power and load shedding in both normal and damage scenarios. The second-stage model aims to further improve the ACD when the ACD of the scheme obtained from the first-stage model cannot reach the target. Specifically, the contribution of each transmission line to the ACD is calculated, and the next hardened line is determined to increase the ACD. This process is repeated until the ACD meets the requirements. Case studies of the modified IEEE RTS-24 and two-area IEEE reliability test system-1996 indicate the proposed TH&P model can meet the requirements for both normal and damage scenarios.

飓风影响下以复原力为导向的输电系统加固和扩建规划
本文提出了一种两阶段输电加固和规划(TH&P)模型,该模型既能满足正常情况下的负荷增长需求,又能满足飓风引起的损坏情况下的恢复能力要求。为了更好地衡量抗灾能力要求,本文提出的输电加固与规划模型包括两个抗灾能力评估指标,即受损情景下的甩负荷(LS)和不同阶段的平均连通度(ACD)。第一阶段模型的目标是在满足负荷增长需求的同时使 LS 最小化,该模型被制定为一个混合整数线性程序 (MILP),以最小化正常和受损情景下输电线路的总规划和加固成本、发电机的运行成本以及风电和甩负荷的惩罚成本。第二阶段模型旨在当第一阶段模型得到的方案 ACD 达不到目标时,进一步提高 ACD。具体来说,计算每条输电线路对 ACD 的贡献,并确定下一条加固线路,以提高 ACD。这一过程不断重复,直到 ACD 达到要求。对修改后的 IEEE RTS-24 和双区域 IEEE 可靠性测试系统-1996 的案例研究表明,建议的 TH&P 模型可以满足正常和损坏情况下的要求。
