experience, we recommend you use a more up to date browser (or turn off compatibility mode in Internet Explorer). In the meantime, to ensure continued support, we are displaying the site without styles and JavaScript. This paper provides an in-depth analysis of photovoltaic (PV) system control within the MATLAB/Simulink environment, focusing on optimizing Maximum Power Point Tracking (MPPT) algorithms for enhanced efficiency under dynamic conditions. While conventional algorithms are widely used, their performance is limited under fluctuating conditions. To address this, we propose a novel hybrid approach combining Incremental Conductance with Fuzzy Logic Control (FLC), utilizing two innovative input variables: the sum of Conductance and Incremental Conductance (SInC) and its rate of change (CSI). The performance of the proposed algorithm, in comparison to other hybrid FLC methods, is evaluated through simulations using a boost converter under dynamic conditions, including abrupt irradiance changes and load variations. The results demonstrate that the proposed hybrid algorithm achieves superior performance, with an average MPPT efficiency of 97.7%, a convergence time of 53.5 ms, and an RMS of 97.8%, outperforming both conventional and other hybrid techniques. This work advances PV system control by providing a robust and adaptive solution for maximizing power extraction under diverse operating conditions.
Operational Methodology & Framework
Figure 1: Conceptual Model & Experimental Workflow for Fuzzy Logic Controller For Solar Mppt Simulink 2. System Architecture & Functional Block Diagram The mounting global demand for energy, fueled by industrial expansion and increased consumption, has intensified the need for improved energy efficiency and the adoption of sustainable, renewable energy sources. The depletion of conventional energy reserves, coupled with environmental concerns and geopolitical challenges, has driven up energy costs, underscoring the urgency of transitioning to renewables such as solar and wind power. However, this transition requires not only the deployment of renewable energy systems but also the efficient extraction and delivery of power at competitive costs 1 , 2 , 3 , 4 .
Experimental Findings & Validation
Photovoltaic (PV) systems, while environmentally beneficial, face significant challenges that limit their widespread adoption. Industrial PV panels typically suffer from low energy conversion efficiencies (below 20%). Changes in sunlight intensity, ambient temperature, and even partial shading can drastically impact their electrical output. Additionally, the natural degradation of PV panels over time, leading to reduced energy production, further contributes to suboptimal performance, particularly in large-scale PV farms 5 . These combined factors often lead to reduced efficiency and reliability, significantly limiting the overall effectiveness of PV systems 6 , 7 .
