Design and performance of low power solar-PV energy generating system with zeta converter

This paper presents the design procedure and performance of a solar-PV (photovoltaic) energy generating system using an isolated zeta converter for meeting an energy demand of rural households. The solar-PV generating system consists of solar panels, a zeta dc-dc converter, a MPPT (maximum power point tracking) controller, energy storage system, VSI (voltage source inverter) and a filter. A feedback PID (Proportional-Integral-Derivative) controller is designed to regulate the output voltage under disturbances at the consumer loads. The system is designed and modelled in Matlab/Simulink and the simulation results are presented to demonstrate its performance in various atmospheric as well as consumer loads condition
