This paper investigates the process of Newton power flow in rectangular form when it is used for systems with small impedance branches, and finds out that the divergence only occurs in the cases which both ends of the small impedance branch are connected to PQ buses. The reason why the power flow diverges under this case and converges under other cases are(More)
Only few switches in a real-time power system are operated during a short interval between the executions of the network topology algorithm, and switch activities just have local affect on network topology. So a fast local network topology method using optimal search direction is presented in this paper. The proposed method has three main procedures:(More)
