in this paper, the static var compensator (svc) has been used to improve dynamic behaviour of power system. to do this, a new objective function is formulated considering power loss reduction, voltage profile improvement and loadability margin decrease. other contribution of this research is proposing a novel structure for particle swarm optimization (pso) algorithm through modifying the initia...

Efficient transmission of power is a pressing concern in modern systems as it could relieve additional investments (e.g., right way) and may improve stability. Non-uniform loading lines (which normally occurs due to the inefficient power) lead overloading few lines. These would then be prone voltage instability. However, this problem aggravated under network contingency condition. This paper fo...

The paper presents a new anticipatory load shedding protection scheme implemented centrally from the energy control centre for loadability enhancement. Most of the schemes available in literature for this purpose are based on information at the current operating condition which are blind to load increase scenario and associated switchings in voltage controlled buses. The proposed scheme anticip...

This paper proposes a new voltage control methodology using the particle swarm optimization (PSO) technique for smart grid loadability enhancement. The goal of this paper is to achieve reliable and efficient voltage profile/stability regulation in power grids. This methodology is based on the decouple power flow equations and the worst-case design technique. Specifically, the secondary voltage ...

In the current power system much concentration is given to the efficient transmission of power from generator side to load end with minimum power loss. To achieve this, the newly introduced FACTS technology is being used. FACTS device such as STATCOM (static synchronous compensator) is used in this paper, for the efficient power transfer between transmission lines. To enhance the loadability of...

One of the factors to maintain system survivability is the adequate reactive power support to the system. Lack of reactive power support may cause undesirable voltage decay leading to total system instability. Thus, appropriate reactive power support scheme should be arranged in order to maintain system stability. The strength of a system capacity is normally denoted as system loadability. This...

The paper considers the problem of nding points of maximum loadability which are closest (in a local sense) to the power system operating point. This optimization problem leads to a set of equations which describe such critical points. Not all solutions of this set of equations are critical points. The paper therefore explores the nature and characteristics of solutions. A two stage algorithm i...
