An Efficient Switched Filter Compensation Used LED Lighting PV-Battery Scheme

Abstract

This study presents a completely stabilized and novel flexible self-adjusting light emitting diode (LED) lighting scheme powered by a PV-Battery and using a pulse width modulation (PWM) switching multi-regulation dual-loop error-driven weighted modified proportional–integral–derivative (WM-PID) accelerated control scheme. The presented scheme incorporates a green plug filter capacitive switched compensator scheme to ensure efficient energy utilization and reduced inrush currents and switching transients. The LED lighting load is regulated using two stabilizing switched filter compensation (SFC) devices located at the DC side common and load buses. It ensures damping of transient voltage and reduces inrush currents for enhanced energy efficient operation and minimal stresses on the solid-state switches. The proposed multi-regulator controller uses a dual-loop error-driven, error-time de-scaled controller for the PWM switching scheme. The dual-action regulator uses total error-driven signal fed to the fast-acting modified proportional–integral–derivative (PID) controller equipped with error-squared acceleration loop and fast response auxiliary derivative type loop, to ensure efficient fast-acting control with minimal inrush conditions, and recovery from load excursions and fault conditions. Moreover, it also changes battery state of the charge (SOC) and solar insolation and ambient temperatures.
