Summary
The report presents modelling and simulation of the off-grid Photovoltaic (PV) power system
using MATLAB Simulink Interface in conjunction with Sim Power toolbox. The off-grid system
comprises of photovoltaic panels, storage battery, inverter, other electronic components like
transformers, diodes and fuses, and various loads including inductors, capacitors and resistors.
All the system components are simulated both in static state and under dynamic conditions to
determine their stability when operating within the desired frequency and voltage limits.
The results verified the effectiveness of the control system and the model components. Since the
entire simulation largely considered the components’ parameters that determined the outputs and
inverter efficiency, we recommend design of off-grid power stems for different applications.
