A CONTROL APPROACH FOR GRID INTERFACING INVERTER IN 3 PHASE 4 WIRE DISTRIBUTION SYSTEM WITH POWER-QUALITY IMPROVEMENT FEATURES
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 4
Abstract
With the increase in load demand, the Renewable Energy Sources (RES) are increasingly connected in the distribution systems which utilizes power electronic Converters/Inverters. Nowadays, 3-phase 4-wire distribution power system has been widely used in residential and office buildings, manufacturing facilities, schools etc This paper presents a novel control strategy for achieving maximum beneļ¬ts from the grid-interfacing inverters when installed in 3-phase 4-wire distribution systems. The inverter can thus be utilized as: 1) power converter to inject power to the grid, and 2) shunt APF to compensate current unbalance, load current harmonics and load neutral current. All of these functions may be accomplished either individually or simultaneously. This new control concept is demonstrated with extensive MATLAB/Simulink simulation studies
