Combination of a large amount of harmonic currents produced by nonlinear/power electronic loads and capacitance in the network usually results in harmonic resonance which is detrimental to the performance of the distribution systems. Over the last few years, there has been a very significant increased in the usage of power electronic loads such as the inverter air-conditioners, inverters refrigerators,...
During the islanding mode, whenever the power grid is not available, distributed-generation (DG) produces sinusoidal output voltage and supplies nonlinear loads, thus voltage at point of common coupling (PCC) becomes non-sinusoidal. The situation gets particularly aggravated during the islanding mode, when the power grid is not available. This deteriorates the performance of other loads connected...
This paper presents a dq0 control scheme for a three-phase four wire shunt active power filter (SAF) based on a three-level neutral point clamped (NPC) inverter. Neutral-point clamped inverter is a widely used topology for utility applications. However, the differential neutral point voltage is fluctuates with different switching states. This phenomenon has to be minimized or disappeared for all power...
