   Design, Control and Loss Analysis of PV-based Shunt Active Filter for Improved power Quality with maximum PV power injection

Abstract: This research proposes the Photovoltaic (PV) based shunt active filter (SAF) connected to the storage device. This scheme generates and injects the maximum PV power into the system and ensures that the grid current is healthy by offering a high filtration quality on the grid side. It provides higher reliability, high efficiency, and increased stability. The control strategy devised for this structure works equally well for the lower and higher PV energy penetration, light and heavy loading conditions, and importing/exporting power to/from the grid. The performance of the overall scheme is analyzed by employing commercial power electronics components, MOSFETs, in the simulation using PLECS and MATLAB Simulink.

   Generalized algorithm for determining the control functions of an AC voltage compensator with a bipolar AC/AC converter

Abstract: Power quality problems in the low voltage distribution grid are related to the development of prosumer electricity generators (especially PV) and the network's inadequacy to new distributed energy sources with significant nominal power. The main problem is related to the increase in voltage above the normative values and its asymmetry. In the scientific literature, one can find many articles describing this problem and methods of its solution based on the use of power electronics systems, energy storage, transformer tap changers or appropriate management of energy demand and production. The paper presents a generalized procedure for determining the control functions of transistors in an AC voltage compensator with a bipolar AC/AC converter. The obtained mathematical relations allow determining the control functions for the amplitude or phase asymmetry of input voltages. The correctness of the determined relations was verified in simulation studies.
