Authors
abstract
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. finally, the effectiveness of the proposed control method is demonstrated by numerical simulations.

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...
