AI总结:

针对传统补救行动方案(RAS)参数固定无法适配电网动态变化的问题,提出基于混合整数二次规划的RAS-SCOPF优化框架,在RTS-96网络验证中实现了更低运行成本且可防范级联停电。

摘要:

补救行动方案(Remedial action schemes, RAS)常被视为新建输电基础设施以缓解系统拥堵的替代方案,因此全球电力系统中的RAS数量迅速增长。但多数RAS依赖固定参数,无法适应电网快速变化的特性。本文提出一种可实现RAS设计流程自动化的优化框架RAS-SCOPF,该框架为混合整数二次规划(mixed integer quadratic program, MIQP),可选择一组最优RAS动作,并在故障发生时最小化切负荷量。研究将RAS-SCOPF的运行成本与标准OPF和SCOPF公式的运行成本进行了对比,此外还采用基于直流潮流的级联故障模拟器(cascading failure simulator, CFS)评估了不同公式对应的级联故障风险。该框架被应用于RTS-96 24节点网络,结果表明引入RAS可让系统以更低成本运行,同时防止任何故障演变为级联停电。

英文摘要:

Remedial action schemes (RAS) are often seen as an alternative to building new transmission infrastructure to relieve congestion in the system. Consequently, there has been a rapid growth in the number of RAS in electric power systems across the world. However, most RAS rely on fixed parameters and hence cannot adapt to the rapidly evolving nature of the electric grid. In this paper, an optimization framework (RAS-SCOPF) to automate the RAS design procedure is proposed. The proposed framework is a mixed integer quadratic program (MIQP) that chooses a set of optimal RAS actions and minimizes load shed when a contingency occurs. The cost of operation of the RAS-SCOPF is compared against those of standard OPF and SCOPF formulations. Moreover, the risk of cascading failure for the different formulations are evaluated using a DC power flow based cascading failure simulator (CFS). The proposed framework is applied to the RTS-96 24-bus network. The inclusion of RAS allows the system to be operated at a lower cost while preventing any contingency from evolving into cascading blackouts.
