I'm excited to share that our collaborative journal paper titled "Improved RCC-Based MPPT Strategy for Enhanced Solar Energy Harvesting in Shaded Environments" has been published in IEEE Access! In this work, we propose an improved ripple correlation control (iRCC) algorithm designed to overcome the challenges of maximum power point tracking (MPPT) in photovoltaic (PV) systems under both uniform and partial shading conditions. Our iRCC method effectively detects and tracks the global maximum power point (GMPP), significantly enhancing energy output, especially in shaded environments. 🔍 Key Highlights: Enhanced Performance: Our proposed iRCC algorithm increases the efficiency of PV system under partial shading condition compared to conventional RCC methods. Dynamic Adaptation: The iRCC method dynamically adapts to changing weather conditions, ensuring optimal energy harvesting. Thorough Validation: The algorithm was rigorously tested through simulations in MATLAB and a hardware prototype, demonstrating superior tracking efficiency. This publication is a result of extensive collaboration and dedication, and I am grateful to my co-authors and the entire research team for their hard work. https://lnkd.in/gWqnyuGC Looking forward to further contributions in the field of renewable energy and continued innovation in control system design. #RenewableEnergy #SolarPower #MPPT #IEEEAccess #Research #Innovation #Collaboration

Proud to anounce that the paper "A computer-assisted Faulted Phase Selection Algorithm for dealing with the effects of Renewable Resources in Smart grids" presented during the NEIS 2023 congress is now available in IEEE Xplore. Link: https://lnkd.in/dcgmrZ4q Abstract: The increase in renewable generation in the grid has brought new challenges for the protection systems currently installed in distribution and transmission networks. Among these challenges is the potential misoperation of the faulted phase selection logic currently implemented in many commercial protection relays. This article presents a Faulted Phase Selection (FPS) algorithm based on incremental line-to-line voltages. Considering the advantages of IEC 61850 standard, the algorithm is implemented in a computer-based system using C++ code. The FPS operation is tested in Hardware-in-the-Loop (HiL) mode using a Real Time Digital Simulator (RTDS Technologies Inc.). Different fault conditions are considered during the test, varying fault type, resistance, and location. Furthermore, evolving faults are also included in the tests. From the study, it is concluded that the proposed algorithm operates correctly in all the analyzed scenarios. Thanks to H2020 FLEXIGRID project and CIRCE - Centro Tecnológico for making this work possible.

Excited to share my latest paper, "Unified Machine Learning Based Fault Detection Strategy Through Voltage-Sensing for Both AC and DC Side Faults in Photovoltaic Farms," published on IEEE Xplore. Photovoltaic (PV) farms, consisting of a vast number of solar panels, are widely recognized as a viable source of renewable power generation. However, fault detection and protection remain critical challenges in PV farms. Conventional methods, such as over-current relays, often prove inadequate, leading to system disruptions. The intricate nature of PV arrays necessitates fast and accurate fault detection. In this paper, we propose a unified machine learning-based approach that detects various fault types on both DC (PV) and AC (grid) sides using just one voltage sensor per side. This innovative approach provides a comprehensive solution for fault detection, classification, and protection—all within a unified framework. #RenewableEnergy #MachineLearning #FaultDetection #PVFarms #SmartGrids

The electric grid is a vast, complex engineering marvel that connects us all. But it was built more than a century ago and is no longer equipped to meet today’s energy demands—especially when it comes to the adoption of renewable resources like wind and solar. As Tapestry’s Ravi Jain argues in a new whitepaper, the transformation of our power grid to digital is not a matter of “if,” but “how fast.” Published in partnership with Alexina Jackson and Colleen Lueken from The AES Corporation, “An Architecture for the Digital Grid” outlines a vision for a secure digital grid that we can move to safely, reliably, and affordably. Inspired by the internet, it outlines the structures, interactions and infrastructure that will be needed to make the transition to a digital grid and the critical role of AI in this process.

🌞 Maximizing Photovoltaic Cell Efficiency: Key Factors to Watch 🌞 In the world of renewable energy, one of the most critical elements is the efficiency of photovoltaic (PV) cells. Efficiency directly determines how much sunlight can be converted into usable electricity. 🔋 Here are a few key factors influencing PV cell efficiency: 1. Material Quality: The purity of silicon or other materials used in PV cells greatly affects performance. 2. Temperature: Higher temperatures reduce the efficiency of PV cells. Innovative cooling techniques can help mitigate this. 3. Light Absorption: Increasing the amount of sunlight absorbed through anti-reflective coatings and surface texturing boosts overall efficiency. 4. Cell Architecture: Advanced designs, such as multi-junction cells, can capture a wider spectrum of sunlight. Improving these factors is essential as we move toward a sustainable energy future. 🌍⚡ What are your thoughts on the latest innovations in PV technology? #RenewableEnergy #SolarPower #Engineering #Sustainability #PVCells #EnergyEfficiency
