摘要

在电力系统运行过程中，经常需要对电力系统的运行可靠性进行评估。如何快速计算运行过程中的可靠性指标是一个关键问题。提出了一种基于直流潮流的发输电系统运行可靠性快速评估方法。在前一次可靠性评估结果的基础上，利用各母线的注入功率对前一次的可靠性指标进行修正，得到新的可靠性评估结果。通过对ieee30系统进行三次可靠性评估，验证了该模型的有效性、高效性和局限性。

A Sensitivity Method for Operational Reliability Assessment of Composite Generation and Transmission System

During the operation of power system, it is necessary to evaluate the operation reliability of power system frequently. One of the key challenges is how to calculate the reliability indices during operation quickly. In this paper, a rapid evaluation method for operational reliability of power generation and transmission system based on DC power flow is proposed. Based on the reliability assessment results of the previous time, the injection power of each bus is used to modify the reliability indices of the previous time, then the new reliability evaluation results can be obtained. The validity, efficiency and limitation of the model are verified by evaluating the reliability of IEEE 30 system at three times.
