Voltage stability improvement is an important issue in power system planning and operation. Voltage stability of a system depends on the network topology and settings of reactive compensation devices. To ensure reliable operation of modern power system characterized by large integration of intermittent renewable sources and multi types of FACTS devices, the voltage stability index becomes a challenge for expert and industrials. In This preliminary study a particle swarm optimization with time varying acceleration (PSO-TVAC) algorithm is proposed for monitoring and improving voltage stability. The proposed technique is based on the minimization of the maximum of L-indices of load buses considering multi STATCOM device under normal case and contingency situation. The proposed algorithm has been tested on IEEE 57-bus test systems and successful results have been obtained.
