Solving Critical Voltage Collapse Power Flow Based onEquivalent Power Method

Targeting the electric power system voltage collapse problem, based on the analysis of the critical voltage collapse, this paper discusses the power flow calculation methods of the power system critical voltage collapse on power-type load. It proposes that collapse branch can be avoided by using characteristics of the AC circuit critical voltage collapse, and the equivalent power be set up to solve the power flow of power system critical voltage collapse and address the non-convergence of the power flow in the critical voltage collapse state. The algorithm is validated through IEEE5 node numerical examples.
