Novel resilient solar photovoltaic power extraction strategy for rural AC micro grids with enhanced incremental conductance based MPPT
This research introduces an innovative Maximum Power Point Tracking (MPPT) technique, the Enhanced Incremental Conductance Algorithm (EICA), designed to optimize solar photovoltaic (PV) system efficiency in rural AC microgrids. EICA dynamically adjusts the step size of a DC-DC Boost converter to prevent MPP divergences, especially under rapid changes in sunlight and temperature. Simulation and hardware results demonstrate that EICA tracks the maximum power point more accurately, offering 22% faster convergence and significantly lower oscillations (15% efficiency increase). The proposed system also achieves lower Total Harmonic Distortion (THD) values, enhancing overall power quality for rural electrification in developing countries.

⚡ Enhanced Incremental Conductance (EIC)
The EIC method is a novel MPPT technique that continuously adjusts the step size for tracking the maximum power point (MPP) more quickly and accurately. It addresses the limitations of conventional incremental conductance by preventing MPP divergences under rapidly changing irradiance and temperature conditions. This is achieved through dual tests for current and voltage changes, leading to robust performance.
converter DC-DC Boost Converter
This converter acts as the interface between the PV module and the grid-side inverter. Its primary role is to elevate the PV output voltage to match grid integration requirements while also being controlled by the MPPT algorithm to extract maximum power. The duty cycle of the IGBT switch within the converter is manipulated by the EIC controller to achieve optimal voltage and power conversion.
🏡 Rural AC Microgrids
The proposed system is designed for interconnected AC microgrids in rural areas of developing countries, aiming to promote rural electrification. These microgrids benefit from the optimized solar PV power extraction, leading to a stable and reliable power supply. The integration ensures improved power quality (lower THD) and efficient energy utilization, critical for regions with limited infrastructure.
