HYBRID INVERTER FOR RURAL ELECTRIFICATION

Abstract

Generating electrical energy in remote areas is challenging due to the scarcity of
energy sources. This paper presents a standalone hybrid solar and wind energy system
designed for rural electrification. The system maximizes solar power extraction using
the Perturb and Observe (P&O) method for Maximum Power Point Tracking (MPPT)
and employs a Permanent Magnet Synchronous Generator (PMSG) to convert wind
kinetic energy into electrical energy. A five-level Cascaded H-Bridge Inverter is used
to convert DC power to AC. To minimize Total Harmonic Distortion (THD), an LC
filter is implemented, with results verified through Fast Fourier Transform (FFT)
analysis. The hybrid energy system model is simulated using MATLAB/Simulink.
