Abstract
This paper presents Silicon Controlled Rectifier (SCR) based power flow control for grid integration in home-scale photovoltaic system. Power flow control is used to control the power flow from the grid if the power from solar panel and battery cannot meet the power requirements of the load. To control the power on the grid, a full-wave SCR circuit is designed. The full-wave SCR circuit serves to convert 220 Volt AC from the grid into 36 Volt DC. The effect of the delay angle of the SCR on the full-wave SCR output voltage is shown in this paper. A filter with a combination of an inductor (L) and a capacitor (C) which is assembled into an LCLC filter in parallel with the load aims to smooth out ripples in the output voltage. The circuit is designed and modeled in The PSpice program code, then simulated and analyzed. The simulation and implementation test results show that the voltage can work at the setpoint voltage at 100-ohm and 50-ohm loads. The full-wave SCR circuit can supply up to 1.8kW based on the simulation results.
