Optimal Setting of Multiple FACTS Devices to Improve Voltage Stability: A Novel GSA

摘要

In this paper, a novel GSA technique is used for improving the voltage stability of the system with multiple FACTS devices. The proposed novel algorithm is used to optimize the location, size and number of FACTS devices. The GSA is enhanced with the use of boundary for optimizing the parameters of the system. Therefore, the voltage stability is improved while satisfying a given set of operating and physical constraints. Here, multiple FACTS devices are used to evaluate the performance of proposed algorithm and these devices are connected in single line and double line of the bus system. The optimal locations and power ratings of the FACTS devices are determined, based on the voltage collapse rating and power loss of the system. The proposed technique is implemented in MATLAB platform and tested with IEEE 30 bus system. The performance of the proposed method is evaluated by locating multiple FACTS devices and compared with the PSO-adaptive GSA and GA-GSA technique.
