Abstract
This paper proposes a hybrid convertible static transmission controller (CSTC), in shunt-shunt mode, with dual active filters and photovoltaic (PV) power integration. The combined system aims to back up and control the power of the transmission transformer, as well as, improve the transmitted power quality. The filters are also designed to eliminate the harmonics due to the injected renewable energy. A new reference generation technique is proposed to inject the solar power into the grid and compensate the system reactive power and current harmonics. Moreover, the varying nature of PV power due to the change in solar radiation and temperature is accounted with the online computation of the DC voltage and power references with the help of the system rectifier. A simulation study adopted by PSCAD-EMTDC environment software is used to validate the proposed system with integration of a solar PV under normal and fault conditions.
