Emotion-Inspired Control for MPPT and Power Factor Correction in a Photovoltaic Converter System Connected to a Three-Phase AC Grid

This paper presents the design and control of a solar photovoltaic (PV) converter system connected to a three-phase AC grid. The system operates in parallel with a local load, enabling power sharing between the PV system and the utility grid. An advanced Maximum Power Point Tracking (MPPT) algorithm, incorporating an emotional controller, ensures efficient power extraction and adaptive response to varying solar irradiance and load conditions. The proposed control strategy ensures maximum extraction of active power from the solar PV panel while simultaneously compensating for the reactive power demand of the AC load. This enables the three-phase AC source to operate at unity power factor. A Hardware-in-the-Loop (HIL) implementation validates the controller's robust performance under varying load conditions and fluctuating solar irradiance.
