Abstract

The nodal and loop equations of electric power network are established relied on the equivalent pi circuit where the load is considered as voltage source and the impedance branch is considered as the link and ground branch is considered as the tree branch in order to perform the hybrid analysis method for power flow calculation in this paper. Moreover, the problems about the node and loop degradation are particularly expatriated with nodal type and load model treating during the process of power flow calculation. It is showed that amount of foundational loops is the amount of total lines minus the amount of degradation loops. Then, the relations combined the loop analysis with the voltage stability are revealed by analyzing the existence and multi-value of the power flow solutions. The case study is made at the IEEE-30 node system and it is tested that hybrid analysis method is the effective for the power flow calculation
