Power quality improvement features on photovoltaic grid connected dual voltage source inverter

In this paper the Dual Voltage Source Inverter (DVSI) is used for improving the reliability and the microgrid system quality. Here, proposed system includes two inverter, which allows the microgrid to replace the energy generated by the source of energy distribution i.e. the PV system, and more than to compensate local and non-linear load conditions. The DVSI is enabled in the network sharing modes and the injection mode conditions for the algorithms of control which are constructed by using the instantaneous symmetric component theory (ISCT). The proposed design provides improved reliability, low bandwidth requirements for the inverter source, filter size reduces the cost and power consumption of the microgrid large powers while using a dc connection reduction Voltage for the main inverter. The factors make the design option of DVSI for the small grid can provide load sensitivity. The algorithm of topology control and approved by many consequences caused by MATLAB/Simulink.
