Abstract:

Voltage and power quality management are the primary components for regulating grid integrated voltage source converters (VSC) during abnormal grid disturbances. This Project offers a distinct control method for controlling a grid-connected solar photovoltaic (PV) system that makes use of an IG integrater. The topology of a three-stage and single stage is investigated. The former purpose is to maintain Photo voltaic power flowing to the power grid although when the system is experiencing irregular oscillations. Normally, the system provides Unity power factor (UPF). Despite this, when the grid voltage varies, reactive power injection keeps the PCC voltage profile within the permissible limits. Moreover, LVRT functioning occurs in the presence of substantial voltage sags.During the night, when there is no PV generation, the VSC and DC link capacitor act as a distribution static compensator, enhancing system usage (DSTATCOM). In contrast to usual control approaches, the power quality of the system is not reduced. The successes of the control are demonstrated through simulation implementation.A comparison with state-of-the-art processes is also emphasized, illustrating the utility of the supplied control.
