This paper presents a methodology for the optimal placement of wind farms and FACTS units in power networks, in order to guarantee the voltage profile and to maximize the loadability of the system under voltage sags conditions. Results shown in the paper indicate that the proposed formulations can be used to determine which the best buses are where the addition of Var sources can enhance the vo...

This paper deals with the optimal location and parameters of TCSC and SVC in electrical power systems, using Particle Swarm Optimization technique (PSO). The objective is to maximize the transmission system loadability subjected to the transmission line capacity limits and specified bus voltage levels. Using the proposed method, the location of SVC and TCSC and their parameters are optimized si...

This paper presents a mixed integer programming based approach for optimal placement of DC model of Unified Power Flow Controller in the deregulated electricity environment. The method accounts for DC load flow equations taking constraints on generation, line flow, and UPFC parameters. The security of transactions has become important issue to reserve the available transfer capability. Therefor...

This paper presents a Modified Shuffled Frog Leaping Algorithm to obtein the optimal number and location of FACTS devices in a power system. Unified Power Flow Controller (UPFC) has great flexibility that can control the active and reactive power flow and bus voltages, simultaneously. Decoupled model of the UPFC is applied to maximize the system loadability subject to the transmission line capa...
