A Generalized Load Flow Method Including the Steady State Characteristic of Dynamic Devices

Abstract

Continuous advances in the field of power electronics have resulted in new technologies connected to power systems. Examples are the different types of FACTS devices connected to the network to perform a number of control functions or to reinforce congested areas. However, conventional power flow methods are not capable of representing these new components with accuracy. This paper presents a generalized power flow method able to include the steady state characteristics of any dynamic device by using the same models considered for time domain simulation. The proposed method allows the monitoring of the performance of the dynamic devices when certain parameter is changed, such as the load level or the voltage setpoint of a given controller.
