Assessment of voltage security in a multi-bus power system using artificial neural network and voltage stability indicators

Abstract EN

In this paper, a new methodology has been proposed for monitoring and assessment of statu voltage stability margins using a unique technique combining artificial neural network (ANN^ and linear voltage stability indicator (LVSi).

A technique for equivalencing of a multi-bus powel system to a two bus radial system has been developed and LVSI has been used as the underlying tool for evaluation of voltage stability margins in a standard SO bus power network.

ANN basei pattern recognition engine has been combined with LVSI to predict voltage security of tht system under various operating conditions.

The proposed technique gives excellent prediction a voltage security under all operating conditions including multiple contingencies.
