Active Power Flow

The aim of this paper is to propose modified centrality measures as a tool to identify critical nodes before a vulnerability analysis is performed in an electrical power grid. Pair dependency centrality is weighted using the grid active power flow, and this becomes the basis to define closeness and betweenness of its nodes, and hence to identify the most critical ones. To support the idea of using modified centralities, four power grids are tested to be either exponential or scale-free. To evaluate the proposal, information obtained via modified centrality measures is used to calculate global efficiency of the power grids.

The continuous change in power demand and supply altered the power flow patterns in transmission networks in such a way that some of the corridors are lightly loaded and some of the corridors get over loaded. This raises serious challenge in operating the power system in secure and reliable manner. To cope with this problem Flexible AC Transmission Systems (FACTS) is used. It plays a very important role in improving the power system operating performance. In this paper load flow models for STATCOM and SVC have been developed. Power flow study of a five bus system is carried out with and without FACTS controllers. Results of the power flow studies are obtained with MATLAB programming.
