this paper presents a novel method to calculate the reference source current and the referencecompensating current for shunt active power filters (sapfs). this method first calculates theamplitude and phase of the fundamental load current from a recursive algebraic approach blockbefore calculating the displacement power factor. next, the amplitude of the reference mains currentis computed with ...

This thesis consists of five self-contained papers on factor demand and market power. The main objective of Paper [I] is to analyze potential effects on the Swedish forest sector of a continuing rise in the use of forest resources as a fuel in energy generation. The background to the problem can be found in the commitments Sweden has made concerning energy policy. Two such commitments are the p...

in this paper, a novel control method for photovoltaic converter connection to the national gridis presented, so in addition to the injection control by solar arrays to the grid, this method cancompensate reactive power and harmonics in the load current. the system will be connected inparallel between the grid and load. the proposed system supplies all load power consumption(including active po...

Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...
