Design, control and performance analysis of a standalone solar-PV energy generating system

This paper presents the design, control and performance of a low power standalone solar-photovoltaic (PV) energy generating system. The system includes a maximum power point tracking (MPPT) controller along with a full bridge DC-DC converter, an energy storage system and a voltage source inverter (VSI). The detailed design and modelling of the system components are given with incremental conductance (IC) approach as a MPPT method. A cascaded controller of the VSI is designed to regulate output voltage and current under varying loads. The performance of the system is presented under varying radiations and different consumer loads
