PROJECT TITLE :

Modified p-q Theory Based Control of Solar PV Integrated UPQC-S - 2017

ABSTRACT:

This paper proposes a modified p-q theory based control of solar photovoltaic array integrated unified power quality conditioner (PV-UPQC-S). The elemental frequency positive sequence (FFPS) voltages are extracted using generalized cascaded delay signal cancellation (GCDSC) that is used in p-q theory based mostly control to generate reference grid currents for the shunt compensator. The solar PV (SPV) array integrated at the DC-bus of the UPQC, provides a part of active load power. The series VSC operates such that it shares a half of the reactive power of the load even beneath nominal grid conditions. The dynamic performance of proposed system is verified by simulating it in Matlab-Simulink using a combination of linear and non-linear load.
