Modern compact fluorescent lamps (CFLs) are reported to have very high levels of current total harmonic distortion, which may have strong negative impact on the quality of supply in distribution networks. This paper demonstrates how a novel circuit-based modelling approach can be used to investigate and quantify the effect of cancellation of harmonics between the groups of modern CFLs. The presented...
This paper presents a component-based modelling approach for developing time-varying harmonic current injection models of the residential load sector. Some initial results of the model are also presented to demonstrate the temporal variations in low-voltage (LV) residential harmonics. The level of detail afforded by the model is illustrated using the proliferation of compact fluorescent lamps as a...
This paper proposes a simple method for aggregating a group of induction motors, which are connected at the same bus. The parameters of aggregate motor are derived using a technique based on energy conservation law. An accuracy of the aggregate model of multiple motors is verified by comparing dynamic responses obtained from the sum of individual motor and the aggregate motor. The obtained results...
This paper presents an aggregate model of multiple induction motors using a single equivalent circuit model, which simplifies the computation while simulating dynamic behavior of large power systems. The simulations and analysis are carried out using MATLAB-based software package. The performance of the aggregation model of multiple motors is verified by comparing the results obtained from the sum...
