Power quality has become an important factor in power systems, for consumer and household appliances with proliferation of various electric/ electronic equipment and computer systems. The main causes of a poor power quality are harmonic currents, poor power factor, supply voltage variations, etc. In recent years the demand for the quality of electric power has been increased rapidly. Power quality...
Innovations in renewable energy technology are becoming important as worldwide needs for affordable, reliable & clean energy grow worldwide. Research is needed for new generation technologies and effective integration of these into electric grid. Renewable sources are abundant particularly in India and we can harness these resources for producing electricity. Globally speaking, wind technology...
In this paper, a new control strategy based on current mode control for dynamic voltage restorer (DVR) is proposed to mitigate the power quality problems in the supply voltage. The DVR is controlled indirectly by controlling the supply current. The reference supply currents are estimated using the sensed load terminal voltages and the dc bus voltage of DVR. The control scheme is based on synchronous...
