Optimizing Large-Scale PV Systems with Machine Learning: A Neuro-Fuzzy MPPT Control for PSCs with Uncertainties

نویسندگان

چکیده

The article proposes a new approach to maximum power point tracking (MPPT) for photovoltaic (PV) systems operating under partial shading conditions (PSCs) that improves upon the limitations of traditional methods in identifying global (GMP), resulting reduced system efficiency. proposed uses two-stage MPPT method employs machine learning (ML) and terminal sliding mode control (TSMC). In first stage, neuro fuzzy network (NFN) is used improve accuracy reference voltage generation MPPT, while second TSMC track MPP using non-inverting DC—DC buck-boost converter. has been validated through numerical simulations experiments, demonstrating significant enhancements performance even challenging scenarios. A comprehensive comparison study was conducted with two algorithms, PID P&O, which demonstrated superiority generating higher less time. generates least loss both steady dynamic states exhibits an 8.2% average 60% time compared methods, indicating its superior performance. also found perform well real-world load variations, 56.1% variability only 2–3 W standard deviation at GMPP.

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

Neuro-Fuzzy Wavelet Based Adaptive MPPT Algorithm for Photovoltaic Systems

An intelligent control of photovoltaics is necessary to ensure fast response and high efficiency under different weather conditions. This is often arduous to accomplish using traditional linear controllers, as photovoltaic systems are nonlinear and contain several uncertainties. Based on the analysis of the existing literature of Maximum Power Point Tracking (MPPT) techniques, a high performanc...

Declarative Systems for Large-Scale Machine Learning

In this article, we make the case for a declarative foundation for data-intensive machine learning systems. Instead of creating a new system for each specific flavor of machine learning task, or hardcoding new optimizations, we argue for the use of recursive queries to program a variety of machine learning algorithms. By taking this approach, database query optimization techniques can be utiliz...
