Modelling of Power Electronics Controllers for Harmonic Analysis

The modelling and quantitative analysis of power electronics controllers based on voltage source converters, for harmonic studies in power systems, are the main objectives of this book. A complete steady-state model, using the harmonic domain, for the voltage source converter based on PWM switching techniques is given. As a modular approach, the voltage source converter model is used to build up models for the STATCOM, HVDC-VSC stations and UPFC. A state-space representation of systems, based on time-dependent Fourier series, is proposed for dynamic harmonic analysis. In this new state-space, the new state variables are the harmonic coefficients of the original state variables. State-space equations for the STATCOM and HVDC-VSC station models are obtained and presented in this book. Finally, a harmonic power flow method, based on the instantaneous power flow balance and Newton-Raphson method, is also developed in this book. The proposed method support all the models developed in the harmonic domain.
