Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

Renewable Power Generation Systems with Active Power Filter Performance Improvement

An active power filter implemented with a four-leg voltage-source inverter using a predictive control scheme is presented. The use of a four-leg voltagesource inverter allows the compensation of current harmonic components, as well as unbalanced current generated by single-phase nonlinear loads. A detailed yet simple mathematical model of the active power filter, including the effect of the equ...

Single-Phase Shunt Active Power Filter Using Indirect Control Method

A single-phase shunt active power filter is used mainly for the elimination of harmonics in single-phase AC networks. In this paper a single-phase shunt active power filter based on, an indirect control technique is designed and simulated. This control technique is achieved by phase shifting the input signal(voltage/current) by π/2.The overall action of the shunt active power filter to eliminat...

Power SystemAnalysis for Nonsinusoidal Steady State Studies Based onWavelets

In this paper power system model is represented in a new domain that relates to Multi-Resolution Analysis (MRA) space. By developing mathematical model of elements in this space using Galerkin method, a new alternative method for power system simulation in nonsinusoidal and periodic conditions is developed. The mathematical formulation and characteristics of new proposed space is expressed. Als...

A New Control Method for Single-Phase Grid-Connected Inverter Using Instantaneous Power Theory

Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...
