A High Efficiency MPPT Based PV System Using DC-DC Converter

This system is linked to a grid-connected single-phase solar PV module. To monitor the strength of the global maximum peak point, MPPT is used. An energy management system's grid is connected to a bidirectional converter. These suggested systems deliver nonlinear power quality output. The harmony search is an upgraded form of the fuzzy logic with machine learning method, It is inspired by the process of making music, and applying the normal probability distribution component enhances its searching performance. A constructed prototype is used to test the control strategies NHS-based MPPT and PNKLMS-based with a reduced sensor approach were considered. NHS is therefore suitable for hardware-based internet searches since it quickly approaches the global maximum power point (GMPP). The NHS algorithm's strong steady-state and dynamic performances are shown in various irradiance, temperature, and partial shade conditions. Situations including overvoltage, undervoltage, harmonic distortion, and load nonlinearity, the power normalized kernel least mean square algorithm's capabilities are also proved without the need of a DC link voltage and voltage sensor. The recommended system's objectivity has been confirmed by these outcomes.
