Electric power is the most essential raw material impacting the bottom line of quality production economically on a commercial scale. It can‟t typically be stored like other commodities and is essentially required with continuous flow all the time. Electric power can be visualized as the epitome of „just in time‟ philosophy used like the components delivered to a production line by a trusted an...

In the last years, the wind power generation incorporated into standard grids has been increased significantly. This situation forced the revision of grid connection code requirements, to guarantee the reliability in systems with high wind power penetration. These strategies were implemented using a Unified Power Quality Compensator (UPQC). A model of wind farm with induction generators connect...

Different from the extant power flow analysis methods, this paper discusses flows for unified quality conditioner (UPQC) in three-phase four-wire systems point of view impedance matching. To end, combined with designed control strategies, establishing method UPQC model is presented, and on basis, system can be equivalent to an adjustable model. After that, a concept matching introduced into stu...

This work presents a distributed generation system (DG) that combines of wind turbine (WT) and photovoltaic (PV) using unified power quality conditioner (UPQC). Along with providing active (AP) to the utility grid, Wind-PV-UPQC improves PQ indicators, for example, voltage drops/surges, harmonics grid voltages, PF. Since depends on dual compensation scheme, parallel converter works as sinusoidal...

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...

The power quality issues are of great concern now a days. The increasing use of power electronic devices based nonlinear loads deteriorate the quality of power. Power electronic appliances are widely used in industrial, commercial and utility system thus leading to various power quality problems. This leads to harmonics being injected into the distribution system and also reactive power burden....

A low carbon, high efficiency and high quality power supply scheme for Distributed Generation (DG) in a micro-grid is presented. A three-phase, four-leg DG grid-interfacing converter based on the improved structure of a Unified Power Quality Conditioner (UPQC, including a series converter and a parallel converter) is adopted, and improved indirect and direct control strategies are proposed. It ...

This paper, presents a new unified powerquality conditioning system (MC-UPQC) , The response of the Multi converter unified power quality conditioner, for different types of controllers are studied. This paper capable of simultaneous compensation for voltage and current in multibus/multifeeder systems. In this configuration, one shunt voltage-source converter (shunt VSC) and two or more series ...
