This paper presents an enhanced Genetic Algorithm (EGA) based approach to solve the Optimal Power Flow (OPF) with FACTS devices to eliminate line over loads in the system following single line outages. The optimizations are performed on two parameters: the location of the devices, and their values. Two different kinds of FACTS controllers are used for steady state studies: Thyristor Controlled ...

This paper discusses control design issues for the existing thyristor controlled series compensation (TCSC) device at Slatt substation on the Slatt–Buckley 500-kV transmission line owned by BPA. The controls were developed at Washington State University (WSU) in a project funded by Bonneville Power Administration (BPA). The project has been carried out in close collaboration between the WSU tea...

Existence of many different Operators in the new electricity has brought many challenges in the system operation and control to obtain minimum generation cost and security. With the growing demand of electricity in the competitive electricity market environment, one or more transmission lines could be overloaded, therefore causing congestion. The congestion can be eliminated/alleviated by impro...

Power system transient stability is one of the most challenging technical areas in electric power industry. Thyristorcontrolled series compensation (TCSC) is expected to improve transient stability and damp power oscillations. TCSC control in power system transients is a nonlinear control problem. This paper presents a T–S-model-based fuzzy control scheme and a systematic design method for the ...

In this dissertation, hybrid tabu search and simulated annealing (TS/SA) approach is proposed to find the optimal placement of multi-type FACTS devices to simultaneously minimize the total generator fuel cost and violation function. The problem is decomposed into the multi-objective optimal placement (MOOP) of multi-type FACTS devices subproblem that is searched by the hybrid TS/SA approach and...

Rapid industrial development and innovations in technology bring about the menace of congestion deregulated power systems (DPS). The transmission lines are continuously working under a stressed condition with reduced transfer capacity. In this situation, losses voltage deviations at load buses increased hence reduce system stability. To mitigate congestion, improving available capability (ATC) ...

Power System Stabilizers (PSS) are generally employed to damp electromechanical oscillations by providing auxiliary stabilizing signals to the excitation system of the generators. But it has been found that these Conventional PSS (CPSS) do not provide sufficient damping for inter-area oscillations in multimachine power systems. Thyristor Controlled Series Capacitor (TCSC) has immense potential ...

The incorporation of renewable energy into the existing electrical system is vital in a competitive system. unpredictable nature sources main obstacle to source integration. Since wind unpredictable, integrating it an thermal requires some additional operating procedures maintain economic and functioning sustainability In power network, uncertainty creates imbalance cost (IC) which directly aff...
