Computer aided voltage stability analysis in power systems

الملخص EN

The current paper aimed to present a computer simulation method to know the power system state which may be in case of voltage collapse, voltage instability or voltage stability by using eigenvalue analysis as well as identifying the weaken nodes in that power system using eigenvector analysis which is used to find the participation factor.

The high participation factor values lead to the weaken nodes in the power system that required to treatment by installing shunt capacitors in those locations to improve the power system performance and reduce the losses power.

The simulation results obtained by tested the proposed method on 30-bus, 30 lines distribution system and the satisfied results are obtained.

The simulation results showed the efficiency and flexibility of proposed algorithm.

Proposed algorithm has been implemented using MATLAB language version (7.5).
