We develop new optimization methodology for planning installation of Flexible Alternating Current Transmission System (FACTS) devices of the parallel and shunt types into large power transmission systems, which allows to delay or avoid installations of generally much more expensive power lines. Our methodology takes as an input projected economic development, expressed through a paced growth of...

The role of Independent System Operator (ISO) in the restructured power industry includes system control, capacity planning, transmission tariff and congestion management; the challenging task being minimizing the congestion. One of the popular techniques used to alleviate congestion is using Flexible AC Transmission Systems (FACTS) devices. The power system generally operates near its rated ca...

The advanced electric power grid is a cyber-physical system comprised of physical components such as transmission lines and generators and a network of embedded systems deployed for their cyber control. The objective of this paper is to qualitatively and quantitatively analyze the reliability of this cyber-physical system. The original contribution of the approach lies in the scope of failures ...

In emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. The flexible Ac transmission system (FACTS) controllers can play an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power system. FACTS...

Loss minimization in power system is an important research issue. Transmission line losses in a power system can be minimized by means of reactive power compensation. The continuous demand in electric power system network has caused it to be heavily loaded leading to voltage instability. This phenomenon has also led to voltage profile depreciation below the acceptable secure limit. The signific...

With the development and advancement of power electronics devices in recent years, changes in the scenario in the field of controlling and handling the power quality issues have been very effective. FACTS devices are the outstanding approach. In this manuscript,we choose one such FACTS device known as STATCOM, a powerful shunt controller, for discussing its impact and depth how to tackle the po...

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...
