This paper investigates the impacts of distributed generator such as solar PV and energy storage on the utility grid. Initially experiment was conducted by increasing PV penetration into the grid and analysed the voltage fluctuation at PCC and harmonic emission on the network. Later, a software model was developed and same impacts were investigated with increased penetration of solar PV. The model...
It is known that a direct application of artificial neural network (ANN) for modeling high power, nonlinear, and impact load may lead to inaccuracies. This paper proposes an approach that the characteristic of the high power, nonlinear and time varying load is modeled by advanced ANN, which is implemented by using back propagation network (BPN) and dynamic time warping (DTW) algorithms. The model...
This paper presents a method that the voltage/current characteristic of the high power, nonlinear and time varying load is modeled by using artificial neural network, this method is implemented by using back propagation network and look up tables which accurately establish high power load model and receive the consumption of the active, reactive and apparent power and voltage distortions in different...
Stationary and dynamic flicker calculation methods are often used for assessing flicker levels throughout the network. This paper introduces a method for calculating flicker levels in the network by analyzing the propagation of voltage interharmonics. Calculated flicker levels are compared with the measurement results. Simplifications of this method are tested on numerous examples.
In order to determine the impact of a fluctuating load on a utility system, the engineer needs accurate measurement and modeling devices. The purpose of this paper is to show methods used in predicting flicker on the utility system due to projected changes in loads. The goal is to demonstrate the usefulness and accuracy of newer measuring and modeling techniques.
