An improved regression‐based perturb and observation global maximum power point tracker methods

IET Renewable Power Generation, Volume 18, Issue 9-10, Page 1646-1660, 17 July 2024.
This paper proposes a regression‐based perturbation and observation method to quickly find a global maximum power point tracker, avoiding being stuck in local maxima, likewise analytical and metaheuristic methods. Linear and non‐linear regression analyses narrow the search area using generated photovoltaic model on a flexible Python environment ...

Adaptive Neuro-Fuzzy Inference System-Genetic Algorithm approach for global maximum power point tracking in PV systems under different shading conditions

Green Technologies and Sustainability
Photovoltaic (PV) panels have become popular energy sources; nonetheless, when under partial shading, their efficiency greatly reduces because of the occurrence of several power peaks or spikes arising because of the variation in irradiance.

Highly Efficient DC–DC Boost Converter Achieved With Improved MPPT‐Based Raspberry Pi for Enhancing Photovoltaic System Generation

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
The operation of photovoltaic (PV) panels in partial shade (PS) conditions (PSCs) lowers the quantity of energy generated due to the hot spots that increase the power loss. In this scenario, a maximum power point tracker (MPPT) is necessary to monitor the power–voltage curve, which features multiple local peaks in addition to one global peak (GP).

Regenerative Braking in PV‐Mounted Electric Vehicle With Reduced Switch VSI‐Driven BLDC Motor and HAP‐FUP Controller

International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.
The electric vehicle’s overall efficiency can be augmented through the implementation of the regenerative braking system (RBS), which serves to extend the drive range. This paper explores a method for further increasing said range by implementing a roof‐mounted photovoltaic (PV) system in conjunction with RBS, resulting in an impressive 25.14% increase
