This paper concerns the optimal location of Flexible AC Transmission Systems (FACTS) in multimachine power system using Genetic Algorithm. The objective is to obtain the bus voltages of the system within healthy limits. TCSC is the FACT device chosen for the proposed algorithm. The location of FACT devices and their rated values are optimized simultaneously. Simulations are done on a power syst...

This paper presents a genetic algorithm based approach for solving security constrained optimal power flow problem (SCOPF) including FACTS devices. The optimal location of FACTS devices are identified using an index called overload index and the optimal values are obtained using an enhanced genetic algorithm. The optimal allocation by the proposed method optimizes the investment, taking into ac...

Traditionally, electric system operators have dispatched generation to minimize total production costs, assuming a fixed transmission topology within the dispatch horizon. Implementation of smart-grid systems could allow operators to co-optimize transmission topology alongside generator dispatch; the technologies that would enable such co-optimization are still regulated as part of the monopoly...

This paper presents an AC Transmission system power flow controlled by injecting a compensating voltage in series with the line and injecting reactive power in shunt with the bus. Static Synchronous Series Compensator (SSSC) and Static Synchronous Compensator (STATCOM) are utilized as a series and shunt compensation, respectively while Unified Power Flow Controller (UPFC) is considered as a shu...

The development of a control system and control strategies capable of governing multiple flexible AC transmission system (FACTS) devices in coordination with a load shedding is described here. The main purpose of the presented coordinated control system is to remove overloads caused by unplanned line outages in transmission network. A sensitivity analysis was used to find out an intercoupling b...

The increasing complexity of the conventional grid due to population growth, advancement in technology, and infrastructures are the factors that contribute immensely to instability, insecurity, and inefficiency of the use of electrical energy. To overcome the problems, the environmental energy sustainability calls for the use of renewable energy for sustainability of power supply. Intermittency...

The Static Var Compensator (SVC) and the Static Synchronous Compensator (STATCOM), as two components of Flexible AC Transmission System (FACTS) devices, play an important role in controlling the reactive power flow to the power network. Because of economic considerations, identifying the best location for installing the SVC and STATCOM is also important. The FACTS devices placement problem is c...

The current social impact of new transmission and distribution lines and the growth in environmental requirements has not lead to the expansion of the electric power grid but to the optimization of the existing assets. Flexible AC Transmissions Systems (FACTS), developed during the last decades of the past century, have become one of the most remarkable solutions for the optimization of the ele...
