“…In [9], a single-phase gridinterfaced PV system has been used for improving the voltage quality at the grid-tied nodes for small voltage dips and harmonic mitigation. In [10], grid-interfaced wind generation systems with active harmonic filtering capabilities have been proposed. Compared to the other control strategies such as PQ theory, and the DQ control method, CPT may be considered a novel alternative method to design and control multifunctional DG inverters.…”

A multifunctional control strategy for a singlephase Asymmetrical Cascaded H-Bridge Multilevel Inverter (ACHMI), suitable for microgrid systems with nonlinear loads, is presented. The primary advantage of ACHMI is to produce a staircase output voltage with low harmonic content utilizing unequal DC voltages on the individual H-bridge cells. In gridconnected mode of operation, the control strategy of the ACHMI is based on the Conservative Power Theory (CPT), providing selective disturbing current compensation besides injecting its available energy. In autonomous mode of operation, two different control methods along with a damping resistor in the filter circuit are developed for regulation of the ACHMI instantaneous output voltage in a variety of load conditions. The first method is a single-loop voltage control scheme without the need of any current measurement. The second one is multi-loop voltage control scheme with a load current feed-forward compensation strategy and preservation of the grid-connected current control scheme. The steady state response and stability of both voltage control schemes are analyzed, and based on the application requirement, the control schemes are implemented individually. The effectiveness of each control strategy is experimentally verified using a hardware-in-the-loop (HIL) setup with the control algorithm implemented in the TMSF28335 DSP microcontroller.

“…No entanto, os autores não determinam a TDH da corrente da rede elétrica antes e depois da filtragem ativa, o que dificulta a análise da estratégia do sistema GIDA/FAP. Em [11], a operação do sistema GIDA/FAP é implementado no sistema dSPACE (DS1103) comercializado no mercado e que possui custo elevado. Os autores apresentam os resultados de simulação e experimentais de TDH com e sem filtragem ativa no CLR, utilizando uma técnica de controle que utiliza controladores de corrente por histerese.…”

Resumo -Neste trabalho descreve-se uma nova proposta de um sistema de geração eólica que controla as potências ativa e reativa e realiza a função de filtragem ativa das componentes harmônicas de correntes da rede elétrica. A compensação harmônica é realizada por um algoritmo aplicado ao conversor do lado da rede elétrica na presença de uma carga trifásica não linear no ponto de acoplamento comum. Esta técnica quando empregada de modo correto melhora a qualidade de energia. O conversor do lado da máquina controla as potências ativa e reativa que são entregues à rede através do controle vetorial por orientação de fluxo do estator. Uma metodologia de projeto dos controladores utilizados nessas técnicas propostas é apresentada. Resultados de simulações e experimentais confirmaram a eficácia e desempenho do sistema proposto. Palavras-Chave APPLICATION OF THE POWER CONTROL FOR WIND POWER GENERATION AND CURRENT HARMONIC FILTER WITH DFIGAbstract -This paper describes a new proposed wind power system which controls the active and reactive generated power as well as performs filtering of the grid currents harmonic components. The harmonic compensation is achieved by an algorithm applied for grid side converter in the presence of a non-linear three-phase load in the point of common coupling. This technique when correctly used improves the power quality. The machine side converter controls the active and reactive power that is delivered to the grid by vector control with the stator field orientation. A design methodology of the controllers used in these techniques is presented. Simulation and experimental results confirmed the effectiveness of the proposed system.

This paper proposes a Power Harmonic Suppression (Damping) (PHS) based reference current generation scheme, which focuses on simultaneous mitigation of harmonic pulsations in electromagnetic torque, stator real and reactive powers, and DC‐link voltage while retaining sinusoidal stator and grid currents and unity power factor at grid side. The crux of this PHS method lies in its ability to eliminate the harmonic powers developed in the DFIG stator and grid at 100Hz, 200Hz, 300Hz, 400Hz, and 600 Hz owing to second, fifth, and seventh harmonic grid voltages. This is achieved as a result of the elimination of natural fluxes developed in the DFIG air gap due to second, fifth, and seventh harmonic distortions in grid voltage. For this, a single concurrent reference current generation technique is developed for RSC and GSC to mitigate the oscillations of electromagnetic torque, stator real and reactive powers, and ripples in DC‐link voltage. Further, the reference rotor currents (positive, negative, fifth, and seventh sequence) are compared with the actual rotor currents using a PI controller to retain sinusoidal stator and grid currents. The proposed scheme's efficacy is validated with PSCAD/EMTDC simulations and using OPAL‐RT OP4510 real‐time simulator, on a 2.3 kVA DFIG.
