This paper proposes a two-stage framework to solve the long-term transmission network expansion planning (TNEP) problem ensuring user-defined reliability levels and wind curtailment over the planning horizon. In the first stage, the static TNEP (S-TNEP) problem is solved to define where a set of new lines must be installed at the end of planning horizon. In the second stage, a multistage procedure is performed to solve the dynamic TNEP (D-TNEP) in order to determine the moment that each transmission line should be built. Both S-TNEP and D-TNEP are decomposed into investment decision and performance assessment through a bi-level scheme based on Benders decomposition; thus, the reliability is considered and evaluated over the planning process. The reliability and performance indexes are obtained through the non-chronological Monte Carlo simulation considering the random behavior of transmission lines failures, load fluctuations and uncertainties over wind availability. The loss of wind probability performance index is introduced to measure the probability of wind curtailment in each connection point of the system, and it is used to prevent wind farms from being underused. The proposed methodology is tested in modified versions of the 24-bus IEEE reliability test system and the IEEE 118-bus test system.

考虑风力发电的可靠性约束动态输电扩容规划

本文提出了一个两阶段框架来解决长期输电网络扩展规划 (TNEP) 问题，确保用户定义的可靠性水平和规划范围内的弃风。在第一阶段，解决静态 TNEP (S-TNEP) 问题以定义在规划范围结束时必须安装一组新线路的位置。在第二阶段，执行多阶段程序来求解动态 TNEP (D-TNEP)，以确定每条传输线应建立的时刻。S-TNEP和D-TNEP都通过基于Benders分解的双层方案分解为投资决策和绩效评估；因此，在规划过程中会考虑和评估可靠性。考虑输电线路故障的随机行为、负载波动和风力可用性的不确定性，通过非时序蒙特卡罗模拟获得可靠性和性能指标。引入失风概率性能指标来衡量系统各连接点的弃风概率，用于防止风电场未得到充分利用。所提出的方法在 24 总线 IEEE 可靠性测试系统和 IEEE 118 总线测试系统的修改版本中进行了测试。它用于防止风电场未被充分利用。所提出的方法在 24 总线 IEEE 可靠性测试系统和 IEEE 118 总线测试系统的修改版本中进行了测试。它用于防止风电场未被充分利用。所提出的方法在 24 总线 IEEE 可靠性测试系统和 IEEE 118 总线测试系统的修改版本中进行了测试。
