Harmonics produced by distributed power generation systems (DPGS) is a main quality issue, particularly due to the number of these connected grid always increasing. This means that, it significant control harmonics caused inverters limit their contrary effects on quality. paper has proposed new proportional current controller (P Resonant Current Controller) with selective harmonic compensator f...

Abstract— This paper presents Neuro-Fuzzy logic based Power Conditioner for elimination of current harmonic. In it neuro-fuzzy based technique is used for generating compensating current to eliminate/reduce the harmonics content which is generated by the system. The modelling of Fuzzy rule base on Neural Network is also mention in this paper. FFT analysis also has been done for the calculation ...

<span lang="EN-US">This paper describes a new strategy for optimizing the switching angles of three-phase inverter in photovoltaic system. It presents non-traditional solutions to problem selective harmonic elimination (SHE) (VSI)-fed induction motor drives. The aforementioned was solved independently by using hybrid genetic algorithms (HGAs) and modified Newton–Raphson method. GAs can ob...

A flexible and versatile solution to voltage quality problems is offered by active power filters. Currently they are based on PWM converters and used to connect to low and medium voltage distribution system in shunt or in series. Active power filters can perform one or more of the functions required to compensate power systems in improving power quality. Hybrid Filter, which is a combination of...

This paper introduces an effective Selective Harmonic Elimination (SHE) modulation technique in a five, seven, and nine-level cascaded H-bridge (CHB) multilevel inverter (MLI). Minimization of the harmonics device counts is basis for ongoing research area MLI. Reduced hence lower Total Distortion (THD), improve output power quality. SHE low-frequency scheme to achieve this goal. techniques are ...

In this paper, a new approach is proposed for voltage and current harmonics compensation in grid-connected microgrids (MGs). If sensitive loads are connected to the point of common coupling (PCC), compensation is carried out in order to reduce PCC voltage harmonics. In absence of sensitive loads at PCC, current harmonics compensation scenario is selected in order to avoid excessive injection of...
