Abstract:

The effective identi?cations of important nodes in power grid are foundations of differentiated management and stable operation of power grid. However, the current studies on this ?eld are not thorough enough. This paper applies the model based on co-citation (MBCC)hypertext induced topic selection (HITS) algorithm used in web page ranking to power grid and proposes an index to determine node importance of power grid from the perspectives of in?ow and out?ow power. MBCC-HITS algorithm is modi?ed considering load, power source, and line ?ow comprehensively for the differences between Internet and power grid in this paper. Then a method for evaluating node importance is proposed using the modi?ed algorithm. Lastly, the rationality and validity of the proposed method are veri?ed by comparisons with other methods in case studies of IEEE 14-bus and 118-bus systems.

Key words:Node importance, MBCC-HITS algorithm, Directed and weighted graph, Inﬂow power, Outﬂow power, Power grid
