Abstract

Solving realistic security-constrained optimal power flow problems In “A surrogate-based asynchronous decomposition technique for realistic security-constrained optimal power flow problems,” we propose a new algorithm for solving a classical problem in power grid operations: the security-constrained optimal power flow, considering its nonlinearities and realistic transitions between nominal and emergency post-contingency operations. Solving security-constrained optimal power flow problems accurately is a critical function, upon which depends the reliability, security, and efficiency of power systems as well as the correct functioning of other critical infrastructure dependent on electricity. The proposed algorithm was extensively tested against many state-of-the-art approaches using realistic and real instances in the ARPA-E Grid Optimization Competition Challenge 1, where it found the best-known solution for 58% of the instances, attained an average gap of less than 0.2%, and obtained the best overall scores, thereby winning all divisions of Challenge 1 with a very strong first place.
基于代理的现实安全约束最优潮流异步分解技术
在“现实安全约束最优潮流问题的基于代理的异步分解技术”中,我们提出了一种新的算法来解决电网运行中的经典问题:安全约束最优潮流,考虑其非线性和标称和应急后应急运行之间的现实过渡。准确求解安全约束下的最优潮流问题是一项至关重要的功能,它取决于电力系统的可靠性、安全性和效率,以及其他依赖电力的关键基础设施的正确运行。提出的算法在ARPA-E网格优化竞赛挑战1中使用现实和真实的实例对许多最先进的方法进行了广泛的测试,其中它在58%的实例中找到了最知名的解决方案,平均差距小于0.2%,并获得了最好的总分,从而以非常强的第一名赢得了挑战1的所有分区。
