Flexible AC Transmission Systems (FACTS) controllers with its ability to directly control the power flow can offer great opportunities in modern power system, allowing better and safer operation of transmission network. In this paper, in order to find type, size and location of FACTS devices in a power system a Dedicated Improved Particle Swarm Optimization (DIPSO) algorithm is developed for de...

FACTS devices allocation and assessing its optimal capacity is one of most discussed subject in scheduling and utilization of the power system. According to value of the matter such as power loss reduction, enhance of the stability margin and also, less cost imposition need to create a partial balance between these several goals, FACTS allocation problem established as a multiobjective optimiza...

This study proposes an algorithm to allocate different types of flexible AC transmission system (FACTS) in power systems. The main objective this is maximize profit by minimizing the system’s operating cost including FACTS devices (FDs) installation cost. Dynamic and steady state restrictions with loads uncertainty are included problem formulation. overall solved using both teaching learning ba...

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...

For system operators, Congestion management is a difficult task as the market’s security and reliability are protected by this methodology. As magnitude of an electric transmission extremely dynamic, limits must be estimated much beforehand, in order to manage congestion issues at right time. Flexible AC systems (FACTS) used control voltage fluctuation adjusting system's real reactive power. A ...

Under new de-regulated environment an open access to transmission system seems to be desired. Determination and enhancement of available transfer capability (ATC) are important issues in deregulated operation of power systems. This paper focuses on the best location and optimal allocation of FACTS devices to improve maximum available transfer capacity (ATC). ATC is computed using repeated power...

Wireless networking is becoming an increasingly important and popular way of providing global information access to users on the move. One of the main challenges for seamless mobility is the availability of simple and robust Channel Allocation algorithm. The radio propagation environment and related handoff challenges are different in cellular structures. A handoff algorithm with fixed paramete...
