Complex network theory has been considered valuable in analyzing the security of networked infrastructures including power grids. However, the traditional pure topological assessment metrics ignore many characteristics in electrical engineering. The most popular metrics for evaluation of nodes or buses in power grids are degree and betweenness. By integration of specific knowledge of electrical engineering, these metrics have been updated to entropic degree and e-betwenness in former studies. However, with consideration of local and global structural features, these two all have defects respectively. This paper made integration of entropic degree and e-betweenness to develop a new concept as extended entropic degree by considering the e-betweenness of line as the weight in entropic degree. The new extended entropic degree can reflect both local and global structural features in evaluation of buses in power grids. This extended entropy degree was tested to verify the effectiveness in IEEE-30, IEEE-118, IEEE-300 and a United Kingdom distribution power grids. The results indicated that this new metric is more reasonable and effective in discovering structural features of buses in power grids.
