Active power flow control in a distribution system using discontinuous voltage controller
This paper proposes a hybrid discontinuous control methodology for a voltage source converter (VSC),which is used in an uninterrupted power supply (UPS) application. The UPS controls the voltage at thepoint of common coupling (PCC). An LC filter is connected at the output of the VSC to bypass switch...

| description | This paper proposes a hybrid discontinuous control methodology for a voltage source converter (VSC),which is used in an uninterrupted power supply (UPS) application. The UPS controls the voltage at thepoint of common coupling (PCC). An LC filter is connected at the output of the VSC to bypass switchingharmonics. With the help of both filter inductor current and filter capacitor voltage control, the voltageacross the filter capacitor is controlled. Based on the voltage error, the control is switched between current and voltage control modes. In this scheme, an extra diode state is used that makes the VSC output current discontinuous. This diode state reduces the switching losses. The UPS controls the active power it supplies to a three-phase, four-wire distribution system. This gives a full flexibility to the grid to buy power from the UPS system depending on its cost and load requirement at any given time. The scheme is validated through simulation using PSCAD. |
