摘要
提出了一种解决动态安全评估中的动态优化问题的方法。文中首先回顾了在连续时域空间的动态优化问题的描述方法,然后通过离散化,将该问题转换成离散时域空间的静态优化问题。解决该问题的方法可以用于评估保证系统动态和静态安全稳定的预防控制措施的效果。特别是,通过一个合同削减程序,可以评估在解除管制的市场环境下用于考虑安全约束的输电管理双边合同的修正电量。
A methodology for treating dynamic optimization problems relevant to dynamic security assessment (DSA) is proposed. This paper starts with an overview on the description of a dynamic optimization problem in the continuous time domain. Through a discretization, a static optimization problem, in the discrete time domain, is obtained. The solution of this problem allows evaluating preventive control actions able to guarantee static and dynamic security of power system. In particular, corrections on bilateral contract power exchanges, through a contract curtailment procedure, are assessed for security-constrained transmission management in a deregulated environment.
