This paper proposes a novel double-loop control strategy for a single-stage boost inverter for a standalone photovoltaic system. This strategy includes compensation filters to avoid high currents and abrupt voltage variations. The final load has a non-linear behavior, representing new electronic components in the grid. The system is implemented in Matlab/Simulink platform, and the entire system is tested in situations like a temporary short circuit, non-linear loads, abrupt load variations, and input disturbance. The proposed control strategy allows the system a continuous operation, which means that the protection system is not triggered. Secondly, the total harmonic distortion (THD) percentage is a maximum of 1.845%, and the maximum voltage deviation compared with the reference error is 4%. Finally, the system efficiency average is more significant than 77% in the operation range.
