安全约束经济调度的基数最小化方法

A Cardinality Minimization Approach to Security-Constrained Economic Dispatch

David Troxell, Miju Ahn, Harsha Gangammanavar

摘要:

我们提出了一个基于阈值的基数最小化制定模型的安全约束的经济调度问题。该模型旨在最大限度地减少系统的运营成本,同时减少在紧急事件期间在紧急操作区运行的线路数量。该模型允许系统操作员监控线路在紧急区域运行的持续时间,并确保它们在系统操作员确定的可接受的可靠性标准范围内。我们开发了一个连续的差分凸逼近的基数最小化问题和解决方法来解决这个问题。我们的数值实验表明,基数最小化的方法降低了整体系统的运行成本,以及避免长时间的高电价在突发事件。

英文摘要:

We present a threshold-based cardinality minimization formulation to model the security-constrained economic dispatch problem. The model aims to minimize the operating cost of the system while simultaneously reducing the number of lines operating in emergency operating zones during contingency events. The model allows the system operator to monitor the duration for which lines operate in emergency zones and ensure that they are within the acceptable reliability standards determined by the system operators. We develop a continuous difference-of-convex approximation of the cardinality minimization problem and a solution method to solve the problem. Our numerical experiments demonstrate that the cardinality minimization approach reduces the overall system operating cost as well as avoids prolonged periods of high electricity prices during contingency events.
