A study on the simple loop formation method of modern power system

Formation of all simple loops is a pivotal step of influencing the efficiency of break point determination algorithm. In view of the characteristics of modern power network loop distribution, based on the method of fundamental loop linear combination, a new simple loop formation method is presented in this paper in which combining a formed simple loop or complex loop with a fundamental loop can form a new simple loop. The new method can not only eliminate most invalid loop combination, but also decrease calculation quantities. The result shows the effectiveness of the new method.
