Available transfer capability (ATC) and transmission reliability margin (TRM) provides imperative information for power marketers and planning sectors in a deregulated power system. The stochastic environment of power system activities, however, made the evaluation of TRM and ATC a intricate and complicated task. A stochastic structure has been established for TRM and ATC calculation with implication...
Protection system plays an important function in maintaining the stability and reliability of the electric power grid. However, most of the major blackouts happened throughout the world has identified that hidden failure of a protection system is one of the major causes of system cascading failure. This paper proposes a computationally systematic approach to assess the impact of protection system...
Protection system hidden failure was identified as one of the main causes of cascading failure. However, in the current practice of power system analysis, protection system is assumed to be perfect and the impact of hidden failures of a protection system is neglected. This paper proposes a systematically accurate technique to evaluate the impact of protection system hidden failures to the probability...
The concern towards power quality has increased rapidly due to the amount of losses it created. Throughout the world, many researchers have proposed a study on various aspects of power quality, which may be used to overcome or reduce the effects. In this paper, a project initiated by the Energy Commission of Malaysia has been carried out to find the level of power quality in Malaysia as well as to...
Occurrences of faults in power system contribute extensive voltage sags (dips) in a network. These occurrences have introduced problems to consumers mainly at 415V where sensitive control equipment is located. This paper investigates the propagation and travelling of voltage sag event under the influence of transformer connections and impedance line length. PSS/ADEPT (Power System Simulator Advanced...
Due to the increasing of power system fault and failure, voltage sag (dip) will occur instantaneously with respect to the fault and failure itself. The power system network consists of high voltage (HV), medium voltage (MV) and low voltage busbar (LV). Monitoring equipment in the power systems network are installed at strategic and appropriate 33/11 kV feeder. The propagation and the travelling of...
