Modelo simplificado de compensador estático de potencia reactiva en el flujo de cargas con inyección de corriente

Abstract

This paper describes Newton-Raphson (NR)

current injection power flow model of a

Static Var Compensator (SVC) to reduce the

complexities of the computer load flow program

codes of a network containing this device.

This model is based on power mismatch

approach. The SVC controlled buses in the

network are converted to PV buses with zero

active power generation at the required voltage

magnitudes. The power mismatch equations for

these connected buses are included and updated

in NR current injection load flow algorithm.

While, the load buses are represented by current

mismatch equations. Moreover, the parameters

of SVC can be calculated using an iterative

process and the final value is updated after the

convergence is achieved.

The developed SVC model enhances the

reusability of load flow program by avoiding

modifications in the Jacobian matrix. This

model is considered the simplest and the

best representation of shunt control devices.

The feasibility of the SVC model has been

validated on the WSCC 9-bus and IEEE 57-bus

transmission systems.
