论文摘要
随着以电子互连可再生能源资源的安装在电力系统中迅速增长，系统频率维护和控制成为挑战性的问题，以维持批量电力系统中的系统可靠性。作为独立系统操作员（ISO）和公用事业控制中心中最重要的两个频率控制动作，经济调度（ED）和自动生成控制（AGC）之间的相互作用吸引了越来越多的关注。在本文中，我们提出了一个基于强大的优化框架，以通过考虑两个层次过程之间的相互作用（即ED和AGC）来衡量系统的灵活性。我们提出了一种使用重新制定技术的切割平面算法，以获得系统的七个不同指数。此外，我们研究了几种系统因素的影响（即操作成本的预算，提高功能和传输线的容量），并以数值方式显示这些因素如何影响系统的灵活性。
As the installation of electronically interconnected renewable energy resources grows rapidly in power systems, system frequency maintenance and control become challenging problems to maintain the system reliability in bulk power systems. As two of the most important frequency control actions in the control centers of independent system operators (ISOs) and utilities, the interaction between Economic Dispatch (ED) and Automatic Generation Control (AGC) attracts more and more attention. In this paper, we propose a robust optimization based framework to measure the system flexibility by considering the interaction between two hierarchical processes (i.e., ED and AGC). We propose a cutting plane algorithm with the reformulation technique to obtain seven different indices of the system. In addition, we study the impacts of several system factors (i.e., the budget of operational cost, ramping capability, and transmission line capacity) and show numerically how these factors can influence the system flexibility.
