A novel on high voltage gain boost converter with cuckoo search optimization based MPPTController for solar PV system

Area of Science:

• Electrical Engineering
• Renewable Energy Systems
• Power Electronics

Background:

• Traditional boost converters for solar photovoltaic (SPV) systems face limitations including low voltage gain, high ripple, and bulkiness.
• SPV systems exhibit non-linear I-V/P-V characteristics and are susceptible to reduced energy yield from partial shading.
• Conventional maximum power point tracking (MPPT) methods struggle with accuracy, speed, and ripple under partial shading.

Purpose of the Study:

• To propose a stackable single switch boost converter (SSBC) integrated with a Cuckoo search MPPT controller for enhanced SPV system performance.
• To address the limitations of conventional converters and MPPT algorithms in terms of efficiency, power output, and ripple under varying conditions.
• To validate the proposed SSBC and Cuckoo search MPPT controller through experimental verification.

Main Methods:

• Development of a novel stackable single switch boost converter (SSBC) topology.
• Implementation of a Cuckoo search algorithm (CSO) for maximum power point tracking (MPPT).
• Comparative analysis of the proposed SSBC with conventional boost converters and various MPPT algorithms (PSO, FPNA).

Main Results:

• The proposed SSBC with a best MPPT (BMPPT) controller demonstrated ripple-free power output under steady conditions, unlike conventional MPPT with CBC.
• SSBC with BMPPT achieved higher power output compared to SSBC with traditional MPPT (TMPPT).
• The efficiency of the SSBC with BMPPT combination was found to be superior to other tested configurations.

Conclusions:

• The stackable single switch boost converter (SSBC) with a Cuckoo search MPPT controller offers a significant improvement in SPV system performance.
• The proposed system effectively mitigates issues related to partial shading and enhances overall energy yield.
• Experimental validation confirms the practical viability and superior efficiency of the developed prototype.
