Abstract

A method of quantitative contribution assessment of power source in critical branch is proposed in this paper. During the various operation modes, a branch must keep its power flow within the critical boundary. A simple branch model is given to represent the overhead line, cable or transformer. The index proximity of criticality (IPC) is formulated to evaluate the severity. An electrical decomposition algorithm is adapted to identify the links between the critical branch and power sources. The decomposition branch which is corresponding to every power source can be used to calculate the IPC. The method is validated through the simulations on IEEE 14-bus power system.
