Improving the performance of UPQC under unbalanced and distortional load conditions: A new control method
This paper presents a new control method for a three-phase four-wire Unified Power Quality Conditioner (UPQC) to deal with the problems of power quality under distortional and unbalanced load conditions. The proposed control approach is the combination of instantaneous power theory and Synchronous Reference Frame (SRF) theory which is optimized by using a self-tuning filter (STF) and without us...
متن کاملDesign & Analysis of ANFIS Controller for Three Phase UPS System under Unbalanced Loads & Distorted grid voltages
This paper proposes a basic ideal voltage control technique for three-stage uninterruptible-control supply frameworks. The proposed voltage controller is made out of a criticism control term and a repaying control term. The previous term is intended to make the framework blunders unite to zero, though the last term is connected to make up for the framework instabilities. In addition, the ideal ...

متن کاملActive Filter Control Method Based on Direct Power Control for Compensating Reactive Powers due to Unbalanced Voltages and Nonlinear Loads
Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...
متن کاملPower System Harmonics Study for Unbalanced Microgrid System with PV Sources and Nonlinear Loads
Harmonics distortion is a crucial problem in microgrid. Harmonic sources can be categorized as two main factors: renewable energy integration and nonlinear loads. Both factors are investigated in this paper. For renewbale energy, photovoltaic (PV) power is one of the most effective solutions for energy crisis and it is showing great potential for serving customers in microgrid. A threephase PV ...
