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...

in recent years, in iran and other countries the power systems are going to move toward creating a competition structure for selling and buying electrical energy. these changes and the numerous advantages of dgs have made more incentives to use these kinds of generators than before. therefore, it is necessary to study all aspects of dgs, such as size selection and optimal placement and impact o...

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...

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...

In this investigation, a novel approach is presented to nd the optimum locations and capacity of Flexible AC Transmission Systems (FACTS) devices in a power system using a fuzzy multi-objective function. Maximising the fuzzy satisfaction allows the optimization algorithm to simultaneously consider the multiple objectives of the network to obtain active power loss reduction; i.e., new FACTS devi...
