Load flow analysis with a neurofuzzy model of an induction motor load
(2009)In the conventional load flow study, the active and reactive powers of all load buses are generally specified. Although the constant power model is applicable for approximate studies, it may not suitable for the motors ... 
Continuation load flow with a neuro fuzzy model of an induction motor for voltage stability analysis
(2010)This paper uses the concept of the continuation power flow analysis used in voltage stability Analysis for control the power in large systems. It uses the PV curves to find the knee point of a certain bus. A neuro fuzzy ... 
Comparison of aggregation methods of induction motor models for transient stability load modeling
(2010)This paper focusses on the comparison of the aggregation methods of multiple induction motors (IM) connected in parallel on the same bus into a single equivalent model using the noload and lockedrotor and transformer ... 
Opportunities and challenges for smart grid communications
(2010)The current power grid is in the verge of being improved. Recent technological advances have made possible the creation of a new and improved grid known as the smart grid. Smart grid allows for better interaction between ... 
Analysis of a fuzzy logic power system stabilizer for stability enhancement
(2010)Modern power systems consist of several generators working synchronously to meet the Power demand. For reliability of these systems, stability must be ensured in case of faults within the system. Faults within a system ... 
Investigating the impact of power system stabilizers in a multi machine system with an induction motor load
(2010)The high reactive power demand by the induction motor load during fault condition due to reduced bus voltages may cause a generator to behave like a voltage source behind the synchronous reactance and its terminal voltage ... 
Power factory load flow sensitivity analysis of an induction motor load model
(2010)Power factory Load flow sensitivity is a method used to obtain certain relationship between dependent and independent variables using differential relationship among physical measure in systems. Voltage sensitivity analysis ... 
Voltage stability analysis using CP_ANN and optimized capacitor bank placement
(2010)Voltage Stability refers to the ability of power system to maintain steady voltage at all buses in the system after being subjected to a disturbance from a given initial operating condition. In this paper, the IEEE 30bus ... 
Suitability of aggregation methods of induction motor models for transient stability load modeling of Kenya power transmission and distribution system
(2010)Current trend indicate that there has been increase on power outage frequency. This has partly been as a result of unstable power system with very small security margin of operation. Therefore, this paper focusses on the ... 
Short term voltage stability analysis of an aggregated industrial load
(2010)Environmental constraints have limited expansion of transmission line networks. And with Power systems being operated close to their security limits, the likelihood of voltage collapses Occurring has increased [1]. In ... 
Investigation of static voltage stability using a modified load flow algorithm and counter propagative artificial neural networks
(2010)In conventional load flow studies, the active and reactive powers of all load buses are generally specified. Thus, by assuming a constant power load characteristic, the impact of the load in the system is overemphasized ... 
Modelling of the industrial load of Bamburi cement company for power system studies
(2010)In the recent past, much attention has been given to models for generation and transmission equipment. The representation of the loads has received comparatively less attention and continues to be an area of greater ...
