In a modern urbanization metropolitan country, energy especially electrical energy is considered as an inevitable necessity because of their need have been seen apparently increase every year. Since then, the congestion in the power system had brought serious problems for the utility in particula. If the problems are not handled with care, a grisly catastrophic event is waiting, thus an appropriate...
Locating the suitable locations in power system for the purpose of Flexible Alternating Current Transmission System (FACTS) devices installation can be realized via wide variety of techniques, and commonly applied by many researchers are sensitivity analysis and optimization approach. On the other hand, there are also various power tracing techniques have been invented by researchers, but their application...
This paper presents a new optimization approach for tuning conventional PID controller parameters of a static var compensator (SVC) which controls a synchronous machine. SVC is designed and implemented to improve the damping of a synchronous generator. Particle Swarm Optimization (PSO) method based PID controller using SVC is implemented in this study. The study involves the optimization of proportional...
Application of the viable technologies in the new millennium has discovered successfulness in reducing undesirable problems related to power system operation. The advent of computational intelligence methods are mostly assisting to achieve high efficiency for controlling the changing of sophisticated process flow in industrials. Congestion problem in power system is a crucial issue as it leads to...
Providing high security and reliability for a power system is compulsory for a transmission service provider (TRANSCO) as this will affect the performance in terms of stability and economy. This can only be achieved by means of ancillary services like reactive power provision. However, to cover the cost of supplying such services, determination of appropriate methods for allocating the cost to consumers...
This paper presents Evolutionary Programming (EP) based optimization technique for estimating PI controller parameters of a static var compensator (SVC) which controls a synchronous machine. SVC is one type of Flexible AC Transmission Systems (FACTS) device, designed and implemented to improve the damping of a synchronous generator, as well as controlling the system voltage. This paper introduced...
A new method to select suitable generators for the purpose of power scheduling has been proposed in this paper, namely Fast Voltage Stability Index Generation Tracing (FVSI-GT). Contrary to previous power tracing techniques which select the generators based on the magnitude of traced power, the proposed technique performs the generator selection based on the stability index contributed by individual...
The inability of traditional methods in providing fair and non-discriminatory transmission service pricing has attracted many researchers to streamline the existing methods, or invent some methods that can improve the weakness. Transaction based allocation like MW mile, contract path, and postage stamp allocation are the examples of traditional technique applied by many transmission service providers...
In deregulated power system, the only way to provide fair and non-discriminatory transmission service pricing is by applying electricity tracing methods. The weakness of conventional methods like transaction based allocation has resulted to inaccurate transmission cost allocation as the physical power system constraints are not taken into account; whereas the proportional sharing principle (PSP) based...
There are various types of method applied for allocating reactive power usage charge among generators and loads, and the most frequent techniques are transaction based charge allocation, sensitivity analysis and reactive power tracing. Studies have revealed that application of power tracing in reactive power market has reflected an acceptable economic signal and in virtue of that, this paper proposes...
