This paper presents a computationally accurate technique used to determine the estimated average probability of a dynamic system cascading collapse considering the effect of hidden failure on a protection system. This requires an accurate calculation of the probability of hidden failure as it will give significant effect on the results of the estimated average probability of dynamic system cascading...
This paper presents a method to estimate voltage profiles on source distribution system using Independent Component Analysis (ICA) algorithm. The profiles are estimated for 24- hours with time interval of 1 minute. The objective of this research is to reduce loss by controlling source of voltage per-unit. When voltage source is controlled, the losses occur on the system is reduced drastically. Power...
The risk of failure in power system components may vary with the change of environment, weather and other operating conditions. The other factors that will contribute to the risk of a system cascading collapse is due to the effect of hidden failure in a protection system. This paper presents a computationally accurate method in determining the risk assessment of a system cascading collapse considering...
The objective of this research is to employ Independent Component Analysis (ICA) for electrical load profiles estimation to ensure proper power usage measurement of the customers. ICA technique is able to separate the mixed signal into their source signals. Using this method, the load profiles on feeder distribution can be estimated without any knowledge of the network topology and electrical parameters...
Hidden failure relay protection is the major cause of cascading failure in power system. Therefore, in this study, a hidden failure model has been developed to study the impact of certain parameter that could cause cascading collapse. The parameters that could lead to major blackout include system loading level, spinning reserve, hidden failure probability and other factors. As the overall load is...
