摘要：This paper concentrates on increasing the loadability of power system. The most powerful
multi-line FACTS controller, Generalized Unified Power Flow Controller (GUPFC) is
considered using power injection model. While finding the optimal installation location for
GUPFC, transmission line thermal limits and bus voltage limits are taken into consideration.
The overall system and area wise loadability is enhanced in the presence of GUPFC with static
and dynamic loads under normal and contingency conditions. A novel optimization algorithm
based on uniform distribution of control variables and two-stage initialization processes included
in conventional Particle Swarm Optimization (PSO) to start the convergence of problem with
good initial value and reaches best final value in less number of iterations. The proposed
methodology is tested on standard IEEE-30 bus test system and the obtained results are quite
encouraging and will be useful for power system restructuring.
