Original Article


This paper describes power quality improvement, which has attracted the attention of the electricity distribution companies and subscribers. The idea of improving power quality is considered as the universal concept for various types of the power system disturbances. These aforementioned disturbances include noise, low voltage, overvoltage and middle harmonics, in general. The key goal of realizing the adaptation-based control strategy in this investigation is to reduce the grid current harmonics, in its efficient manner. It should be noted that there are some traditional and state-of-the-art techniques to improve power quality through the realization of active, passive or hybrid filters, respectively. In accordance with the growing applications of the renewable energy sources in distribution grids, the investigated research proposes the renewable energy sources in the studied grid. In the strategy presented here, the background of this topic is extensively considered and subsequently the above-referenced adaptation-based control strategy is designed, in order to deal with the converter signals, which are connected to the point of common coupling and also the direct current link. In summary, the main contribution of this investigation with respect to the state-of-the-art outcomes is made to improve power quality of the grid side and also to handle the transfer of the power between the renewable energies and the corresponding grid, as well. The validity of the investigated outcomes is tangibly verified by considering the benchmarks, correspondingly.
