Abstract
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.
