A New Approach with Modeling the Combination of Unified Power Quality Conditioner and Photovoltaic Arrays
ABSTRACT This paper presents a system that provides photovoltaic generation as well as the functions of a unified power quality conditioner (UPQC). The system can be controlled for current harmonics and reactive power compensation simultaneously by using a converter operating as active shunt filter. The other converter is used as active series filter and it compensates voltage harmonics or volt...
متن کاملDelay Dependent H∞ Based Robust Control Strategy for Unified Power Quality Conditioner in a Microgrid
This paper proposes a novel robust control scheme based on delay-dependent H∞for unified power quality conditioner (UPQC) in a microgrid under the influence of the delay and parameter uncertainties. A new UPQC model considering the effects of the delay and parameter uncertainties is established. Then, the H∞ controller is designed based on the cone complementarity linearization (CCL) algorithm....
متن کاملA Control Strategy for Unified Power Quality Conditioner
This paper presents a control strategy for a Unified Power Quality Conditioner. This control strategy is used in three-phase three-wire systems. The UPQC device combines a shunt-active filter together with a series-active filter in a backto-back configuration, to simultaneously compensate the supply voltage and the load current. Previous works presented a control strategy for shunt-active filte...
متن کاملDifferent Control Strategies for Unified Power Quality Conditioner – A Review
Power quality has become an important factor in power systems. The main causes of a poor power quality are harmonic currents, poor power factor, supply-voltage variations, etc. To mitigate power quality problems, we have various equipments like active filter, passive filter, unified power flow controller and unified power quality conditioner etc. Among from them unified power quality conditione...
متن کاملA Novel Flexible Control Strategy for Unified Power Quality Conditioner
This paper presents a novel flexible control strategy for Unified Power Quality Conditioner (UPQC), which achieves more flexibility in compensation of power quality disturbances as compared to the existing methods. The proposed control strategy provides priority-based compensation as well as full and standard-based compensation considering the rating of series and shunt parts of a UPQC. The pri...
