Biogeography-based optimization for voltage stability improvement and reactive reserve management


Abstract: This paper proposes a biogeography-based optimization algorithm to enhance the voltage stability of a power system. It computes the optimal quantity of reactive power support with a view to place the static VAR compensator at the most appropriate nodes. The scheme inflicts an effective management of VAR resources in the process of improving the voltage profile and reducing the network losses. It includes the results of IEEE 30-node system to illustrate the feasibility of the approach.

Keywords: Voltage stability, biogeography-based optimization, real power loss minimization, static VAR compensator, FACTS devices
