There is growing interest in renewable energy around the world. Since most renewable sources are intermittent in nature, it is a challenging task to integrate renewable energy resources into the power grid infrastructure. Distribution systems provide standby service during utility outages and when operated during peak load hours, potentially reduce energy costs. This paper presents a grid inter...

The study is done in the field of inverter topologies, which is used to interface a wind energy module to the power grid/load. The boost converter and inverter are developed with focus on low cost, high reliability and massproduction. The switching strategy to control ...

A new approach to electrical load forecasting is investigated. The method is based on the semi-parametric spectral estimation method that is used to decompose a signal into a harmonic linear signal model and a non-linear part. A neural network is then used to predict the nonlinear part. The final predicted signal is then found by adding the neural network predicted non-linear part and the linea...

Abstract— A Fourier analysis of on-chip signals in CMOS integrated circuits is presented in this paper. It is demonstrated that on-chip signals can be approximated by a Fourier series up to the th harmonic component. The effective load impedance characterizing a distributed RC and RLC line driven by a CMOS logic gate is based on a Fourier analysis of the on-chip signals. The voltage waveform ba...

Pulse width modulation (PWM) converters are frequently used due to unity power factor operation with reduced total harmonic distortion (THD) at ac mains and also provide constant-regulated dc output voltage even under fluctuations of ac voltage and dc load. This paper contains the harmonics analysis of sinusoidal PWM (SPWM) technique and space vector PWM (SVPWM) technique for three-phase AC to ...

This paper presents a novel way of generating the reference currents for an active filter and/or a static compensator. A compensator structure is proposed which is capable of balancing an unbalanced delta-connected load that may also draw harmonic currents. In addition to balancing the load, the supply side power factor is also made unity. The theory of instantaneous symmetrical components is u...

A robust controller for a single-phase Pulse-Width Modulation (PWM) inverter is designed. The single-phase PWM inverter generates an AC sinusoidal output from a DC link voltage. Robustness of the output waveform against load variations and minimum Total Harmonic Distortion (THD) are the main goals in this design. The importance of this design methodology results from the changes in the inverter...

This paper describes the finite element modelling, dynamic testing and finite element model updating of a newly constructed, 35m span, cable-stayed footbridge. A numerical simulation, using an updated FE model, was conducted to evaluate the accelerations that would be induced by a walking pedestrian. The results from the simulation were compared to corresponding experimental measurements, and w...

This paper proposes a simplified equivalent circuit model that can be used in the presentation of characteristic harmonic components generated by full wave diode rectifiers. In the model, the load current is assumed to be constant as in many industrial applications. In order to obtain an accurate and exact analysis, the proposed model involves both current harmonics on AC side and voltage harmo...
