The enhancement in electric power quality using a single-stage solar PV integrated Unified Power Quality Conditioner (UPQC) has been discussed this paper. UPQC is the combination of Distributed static compensator (DSTATCOM) and Dynamic Voltage Restorer (DVR) having common DC voltage supply link. DSTATCOM compensates for load current associated problems like factor improvement, even odd harmonic...

Based on reactive power-voltage characteristics analysis of air conditioners, the effects of air conditioner load on voltage stability of an urban power system are investigated in this paper. Indexes for evaluating bus voltage security are proposed, and static voltage stability analysis method is adopted. The computational analysis of a real urban power system in East China shows that air condi...

In this paper a hybrid active DC line conditioner for fluctuations and ripples reduction in voltage and current of DC power systems is proposed. Malfunctions in operation of equipments and systems which are supplied by low quality distribution power systems are one of the main effects of DC voltage ripple. In the proposed configuration a hybrid system including series and shunt active line ...

Abstract A fuzzy-integrated sliding mode-based hybrid controller (FISMHC) attributed to unified power quality conditioner (UPQC) was proposed in this study through implementation with solar integrated fuel cell incorporation of UPQC within sequence designed for active filters series and shunt configurations under shared structure DC-link capacitor deployment. Furthermore, the scheme FISMHC (U-F...

This paper explains a new proposal for the placement, integration, and control of unified power quality conditioner (UPQC) in distributed generation (DG)-based grid connected/autonomous micro grid/micro generation (μG) system has been presented here along with fuzzy logic controller. Here we using fuzzy logic controller instead of using other controllers. The DG converters (with storage) and th...

Mitigating power quality issues in distribution systems is of utmost importance to both electricity consumers and suppliers as it improves the system’s efficiency, reduces costs, maintains continuous supply, diminishes requirement for frequent maintenance. Custom devices were introduced eliminate like voltage sags, swells, transients, imbalances, current harmonics arising systems. Unified condi...
