In this paper the three-phase 7-level Packed U-Cell (PUC) converter has been employed as a shunt active power filter (APF) to compensate the load harmonics in a power network. Using multilevel converter as APF results in generating low distortion waveforms as well as operating in low switching frequency. A PI controller has been used to compensate the load harmonics and to correct the source side...
This paper proposes a linear algorithm to optimize the compensation of reactive power, harmonic distortion and unbalanced load applied to distributed electronic power processors, for example, active power filters and/or photovoltaic grid-connected inverters, especially when their power capacity is limited. The optimized compensation consists in achieve, in terms of power quality, the best performance...
This work presents an adaptive nonlinear control strategy in a PI controller applied to a single-phase shunt active power filter. This strategy is based on a Gaussian-shaped function, where the control gains are defined as a nonlinear function of the input. The single-phase shunt active power filter application has two control loops, the DC bus voltage control loop and the compensating current control...
The main objective of a photovoltaic (PV) inverter is inject the PV power into the grid. However, due to variations in solar irradiance, inverters have a current margin, which can be used in reactive power and harmonics compensation. This possibility, known as multifunctional operation, can be interesting in terms of power factor improvement and reduction of nonlinear loads impact at point of common...
