Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: This paper discusses the design of a multivariable control for unified power flow controller using evolutionary optimization algorithms. It utilizes two biologically inspired optimization algorithms; the particle swarm optimization algorithm and biogeography optimization algorithms, to obtain the optimal set for the controllers of the UPFC. The UPFC is to control the active power flow through the line, regulate the AC bus voltage, regulate the DC link voltage, and damp the low frequency oscillations in the network through a set of PI controllers and a two stage lead lag compensator respectively. The obtained controllers are then verified through time domain simulation for different variable control to assess the capability of this multivariable control scheme.
