This paper presents the introduction of various FACTS controllers such as SVC, TCSC, TCPAR or TCPAT, SSSC, STATCOM, UPFC, IPFC, GUPFC, HPFC for operation, control, planning & protection from different performance point of view such as increased the loadability, improve the voltage profile, minimize the active power losses, increased the available transfer capacity, enhance the transient and ste...

The paper mainly deals about the application of flexible AC transmission system (FACTS) to increase the power transfer capabilities for new operating scenarios in the bulk power systems. With the effect of FACTS technology improves transmission capabilities to reduce the system losses, and also improves the loadability of the power system. FACTs technology allows a better utilization existing t...

Due to the ever increasing demand for power, environmental constraints in expansion of transmission networks and the emerging scenario of restructuring of power system networks, the transmission lines are prone to be operated under heavily stressed conditions. In such a heavily stressed condition, there is a risk of line outage and the consequent voltage instability. This necessitates voltage s...

In this paper, a novel method using Bees Algorithm is proposed to determine the optimal allocation of FACTS devices for maximizing the Available Transfer Capability (ATC) of power transactions between source and sink areas in the deregulated power system. The algorithm simultaneously searches the FACTS location, FACTS parameters and FACTS types. Two types of FACTS are simulated in this study na...

is an issue that needs due thoughtfulness from researchers in the horizon of unbundling of generation and transmission. Electric power systems are exposed to various contingencies. Network contingencies often contribute to overloading of branches, violation of voltages and also leading to problems of security/stability. To maintain the security of the systems, it is desirable to estimate the ef...

Congestion management is one of the technical challenges in a Deregulated power system environment. Two types of Methodologies used in congestion Management are non-cost free methods and cost free methods. In this research work congestion is relieved by using cost-free methods considering FACTS Devices such as TCSC(Thyristor controlled series Compensator) and UPFC (Unified Power Flow Controller...

The paper summarizes new control designs developed at Washington State University for the control of existing SVC’s, and TCSC owned by Bonneville Power Administration. The new controls are primarily aimed at improving transient stability of the WSCC western electric power system. The proposed controls are heuristic and are nonlinear. They are shown to be very effective in increasing the operati...

This paper demonstrates the phase imbalanced series capacitive compensation concept to enhance power system dynamics as it has the potential of damping power swing as well as sub synchronous resonance oscillations. A scheme for a phase imbalanced capacitive compensation is shown. It is a “hybrid” series compensation scheme, where the series capacitive compensation in one phase is created using ...
