Wind power generation is grasping more attention nowadays because it offers the benefits of reduced cost, increased efficiency, less pollution and so on. But the known disadvantage is that the integration of wind farm with grid leads to many power quality problems such as voltage sag, swell, unbalance, harmonics, flickers etc. This paper concentrates mainly on diminution of source voltage sag a...

In this paper, a simplified control algorithm based on unit vector template generation (UVTG) is proposed for a stardelta supported three-phase four-wire (3P-4W) unified power quality conditioner (UPQC) topology for the improvement of different power quality problems. Different topologies reported in literature for 3P-4W UPQC use active compensation for the mitigation of source neutral current ...

In a modern power system, the unified quality conditioner (UPQC) is considered to be most effective device for mitigating problems. The use of dynamic voltage restorer (DVR) active-reactive power-sharing reduces loading on UPQC in all operating conditions, leading better system efficiency and reliability. VA DVC can controlled by maintaining proper angle between load source voltage. this paper,...

Nowadays, integration of renewable sources into the local distribution system and nonlinear behavior advanced power electronic equipment have made a large impact on quality (PQ). The unified conditioner (UPQC) is multifunctional FACTS device, which combination both shunt active filter series filters via common DC link. Presently, artificial intelligence playing vital role in development intelli...

In order to deal with power quality problems under distortional and unbalanced load conditions, this paper presents a new control method for a four-wire three-phase unified power quality conditioner (UPQC) which is based on instantaneous power p-q theory. The proposed control approach is based on instantaneous power and is optimized by using a self-tuning filter (STF), without using any low-pas...
