Photovoltaic (PV) system as one part of distributed energy resources is becoming an alternative for low and medium distribution network microgrid. By the reason a wide implementation power electronic non-linear loads, harmonics distortion main problems systems. There are several filter types to mitigate harmonics. The passive distinguished by its simplicity economical options from another filte...

Due to a rising share of power electronic devices in networks and the consequent rise harmonic distortion, impedance resonances are an important issue. Nowadays, frequency scan method is used for resonance phenomena identification analysis. The main disadvantage its inability decouple different phenomena. This means that also unable provide sufficient information about effects parameters networ...

The development of a reliable power filter is essential for meeting the need high-quality power. Current and voltage harmonics are major contributor to poor quality must be eliminated. Shunt active filters (SAPFs) can installed reduce negative effects harmonics. Fuzzy logic proportional integral (PI) controllers excel at regulating DC link in shunt (SAPFs). This research assessed how well Parti...

In recent years, with the widespread use of non-linear loads power electronic devices associated penetration various renewable energy sources, distribution system is highly affected by harmonic distortion caused these sources. Moreover, inverter-based distributed generation units (DGs) (e.g., photovoltaic (PV) and wind turbine) that are integrated into systems, considered as significant sources...

Dynamics and stability of average current-mode control of buck converters are analyzed by sampleddata and harmonic balance analyses. An exact sampled-data model is derived. A new continuoustime model “lifted” from the sampled-data model is also derived, and has frequency response matched with experimental data reported previously. Orbital stability is studied and it is found unrelated to the ri...
