  • Artificial neural network-based flexible power point tracking for enhanced dynamic response of grid-connected photovoltaic systems
    Néstor F. Guerrero-Rodríguez, Robert Mercado-Ravelo, Rafael Omar Batista-Jorge, Vrindarani Núñez-Ramírez, Francisco.A. Ramírez-Rivera, Rubén D. Ramos Ciprian, Alexis B. Rey-Boué, Enrique Reyes-Archundia
    Energy Reports, 2025
    The widespread adoption of photovoltaic (PV) systems has accelerated in recent years due to technological maturation, reduced manufacturing costs, and enhanced power electronics enabling reliable grid integration. Additionally, the global transition toward low-carbon energy sources and the implementation of favorable energy policies have reinforced this trend. However, the intrinsic variability of PV generation driven by climatic and load fluctuations remains a challenge for maintaining grid stability. To address this, a Flexible Power Point Tracking (FPPT) algorithm based on Artificial Neural Networks (ANN) aimed at improving the dynamic response of grid-connected PV systems is proposed in this paper. A PV system, modeled in MATLAB/SIMULINK R2022b, simulates a two-stage, grid-connected PV generator with a rated capacity of 3.68 kWp and programmable local loads. The ANN was trained using real-world data collected in Santo Domingo, Dominican Republic, via MATLAB’s NNSTART toolbox. Validation was conducted through Controller Hardware-in-the-Loop (CHIL) simulations. The results reveal that the proposed ANN-FPPT algorithm accurately and consistently adjusts to the changes in irradiance received by the PV array with 99.67 % accuracy, while the traditional P&O-CPO featured 92.34 %, based on the Mean Absolute Percentage Error (MAPE). The proposed approach demonstrated superior responsiveness and stability, especially when operating to the left of the maximum power point, where it maintained higher accuracy across a wider load range.

    Néstor F. Guerrero-Rodríguez, Daniel A. De La Rosa-Leonardo, Ricardo Tapia-Marte, Francisco A. Ramírez-Rivera, Abraham Manilla-García, Enrique Reyes-Archundia, Eilen García Rodríguez
    Energy Conversion and Management X, 2025
    This study investigates the potential of green hydrogen production from small and large-scale photovoltaic water electrolysis systems under tropical climate conditions, with particular emphasis on the Levelized Cost of Hydrogen (LCOH) in Santo Domingo, Dominican Republic. The hydrogen production system was developed using MATLAB/SIMULINK R2023b. The system simulation incorporates a commercial proton exchange membrane (PEM) electrolyzer, driven by a DC/DC converter, is also evaluated under varying environmental scenarios based on real meteorological data for temperature and solar irradiance. Dynamic simulations were performed to analyze the relationship between solar resource availability and hydrogen production. Results indicate that at small-scale 3.68 kWp PV + 0.017 kW PEM, LCOH is 104.52 USD/kg for PV-only compared to 17.09 USD/kg for a grid sourced electricity case. At large-scale 100 MWp PV + 60 MWe PEM, LCOH falls to 7.05 USD/kg under PV-only operation Utilization factor U f = 0.31 and 3.61 USD/kg with grid supplied backup U f = 0.85 illustrating the massive cost reduction achievable through economies of scale. Model validation showed a high degree of accuracy, with an average percentage error of 1.41 % when comparing simulated and manufacturer provided parameters curves. A comparative carbon footprint analysis demonstrated the environmental advantages of PV driven hydrogen production over conventional fossil fuels methods. These findings are especially relevant for such climates and support the advancement of Sustainable Development Goals 7 and 13 positioning green hydrogen as a key vector for the clean energy transition.

    Vrindarani Nuñez-Ramírez, Néstor F. Guerrero-Rodríguez, Rafael Omar Batista-Jorge, Robert Mercado-Ravelo, Francisco A. Ramírez-Rivera, Julio A. Ferreira, Rubén D. Ramos-Ciprian, Enrique Reyes-Archundia
    Data in Brief, 2025
    This paper presents a dataset of non-linear household loads in Santo Domingo, Dominican Republic, obtained through a structured data collection and processing methodology. The dataset comprises high-resolution voltage and current waveforms, along with key electrical parameters such as harmonic profiles, voltage, current, frequency, and crest factors. Measurements were conducted using the METREL MI 2883 power quality analyzer on seven representative household devices: a refrigerator, air conditioner, smart TV, microwave oven, smartphone charger, laptop charger, and uninterruptible power supply (UPS). These devices were selected to capture the diversity of modern household loads, which contribute to harmonic distortion and impact power quality. The dataset enables studies on power quality analysis, and harmonic mitigation strategies. It is particularly suited for validating active power filters, modeling real-world non-linear loads in advanced simulations such as Controller Hardware-In-the-Loop (CHIL). The dataset is openly available for further research applications in power system studies, filter design validation, and energy efficiency analysis.
  • Comparative Study of the Grid Current Harmonic Attenuation in a Photovoltaic Generator Due to the Influence of the Synchronization Strategy
    N.F. Guerrero-Rodríguez, F.A. Ramírez-Rivera, R.O. Batista-Jorge, Julio A. Ferreira, Robert Mercado-Ravelo
    International Journal of Electrical and Computer Engineering Systems, 2025
    The present paper studies the current harmonic attenuation for four synchronization strategies commonly used in inverters for photovoltaic power generation. In a model of a 6kWp photovoltaic generator, the four synchronization strategies are implemented in the inverter controller. Real-time simulations are performed, for this purpose, the models of the photovoltaic generator and the utility grid were embedded in an OPAL-RT OP5707XG simulator. The distortion of the grid current for each synchronization strategy is analyzed using its corresponding frequency spectrum and a comparison is made with the IEEE Std. 519-2022 standard. The purpose of this test is to observe the effect of the synchronization strategy on the harmonic attenuation of the grid currents. The results show that one of the synchronization strategies evaluated in this work may be sufficient for the system to comply with the harmonic standard for photovoltaic generators without the use of harmonic compensation structures or active harmonic filters. The evaluation of the harmonic distortion behavior of photovoltaic generators as a function of the synchronization strategy used in the inverter controller is the principal work contribution.
  • Experimental Characterization of Thermal Conductivity with a New Compact Hot-Box Prototype
    Francisco A. Ramírez-Rivera, Néstor Guerrero-Rodríguez, Yokasta García-Frómeta, Diógenes Vargas, Mauricio Montanaro
    Applied Sciences Switzerland, 2025
    In this study, a new compact “hot-box” prototype with a volume of 0.602 m3 has been designed, instrumented, and implemented to experimentally characterize the thermal conductivity of specimens measuring 25 cm × 25 cm, with the thickness of the specimen varying up to a maximum of 10 cm. The prototype features a novel design aimed at enhancing flexibility and speed in changing specimens, thereby reducing downtime when testing different materials. It requires minimal space and incurs low development and maintenance costs. To validate the prototype’s functionality for measuring thermal conductivity, an oak wood specimen with a thickness of 3.81 cm was experimentally tested. The results indicate that the control system maintains key parameters under steady-state conditions for a significant duration. The thermal conductivity obtained for the oak wood specimen is 0.1695 W/m·K, with an expanded uncertainty of 0.0183 W/m·K for a 95% confidence interval.
  • Harmonic distortion caused by non-linear household loads: Measurement and modelling
    Vrindarani Nuñez-Ramírez, Néstor F. Guerrero-Rodríguez, Rafael Omar Batista-Jorge, Robert Mercado-Ravelo, F.A. Ramírez-Rivera, Julio A. Ferreira, Rubén D. Ramos-Ciprian
    Results in Engineering, 2025
    This study presents the modeling and validation of non-linear household loads in a single-family house in the Dominican Republic for harmonic analysis using a comprehensive methodology. Actual measurement data from seven non-linear household loads were captured with a METREL MI 2883 power quality analyzer, with the laptop charger exhibiting the highest harmonic distortion, showing a Total Harmonic Distortion of current (THD I ) of 126.97 %, and the fridge with the lowest, at 14.25 %. These data were then modeled in MATLAB/Simulink for real-time execution on an Opal RT 5700XG simulator. A novel approach for accurately replicating harmonic waveforms and characteristics of real loads is introduced, enabling precise evaluation of Active Harmonic Filters (AHFs) and control strategies in Hardware-in-the-Loop Simulation (HILS) configurations. Validation tests confirmed the reliability of the methodology, with percentage deviations consistently below 3 % between Simulink and measured values, and an average RN_RMSE of 2.19 % between MATLAB/Simulink and RTDS simulations. Specifically, RN_RMSE values ranged from 0.82 % for the microwave oven to 3.28 % for the smartphone charger, with the highest accuracy observed in the microwave oven and the largest deviation in the smartphone charger. The methodology consistently achieved deviations below 5 % across all validation scenarios. These results establish the effectiveness of the proposed methodology in achieving high-fidelity modeling non-linear household loads. The primary contribution of this work lies in advancing beyond traditional approaches reliant on generic models, providing a practical and accurate framework for the design and optimization of harmonic mitigation strategies aligned with real-world conditions.
  • Modelling real non-linear loads for a Controller Hardware-in-the-Loop configuration to evaluate a Shunt Active Power Filter
    N.F. Guerrero-Rodríguez, Vrindarani Nuñez-Ramírez, Rafael Omar Batista-Jorge, Robert Mercado-Ravelo, F.A. Ramírez-Rivera, Julio A. Ferreira, Enrique Reyes-Archundia
    Energy Reports, 2024
    This work shows the design and validation of a Shunt Active Power Filters (SAPF) using Controller Hardware-In-the-Loop (CHIL) Simulations by using a OP5707XG Real-Time Simulator module provided by OPAL-RT, an external OP8666 controller, a host PC and an oscilloscope for visualization. A novel methodology for the modelling of real non-linear electrical loads by making use of MATLAB/SIMULINK is presented. This allows, in conditions like real physical systems, an evaluation of the behavior of active filters before their prototyping, allowing improvements to be made in their design. For the compensation strategy, the calculation of a compensation current from the estimation of the ideal current is used. This strategy is implemented in a microcontroller system for validation with a CHIL configuration simulation. The results have demonstrated significant progress in harmonic mitigation, with the effectiveness of the SAPF in reducing the current Total Harmonic Distortion (THD) across various load types firmly established. As demonstrated in the test cases, the SAPFs significantly reduced THD from significant double-digit percentages to values well below 3 %. This confirms their significant impact on maintaining the integrity and quality of the power system.
  • Ensemble Learning Algorithms for Solar Radiation Prediction in Santo Domingo: Measurements and Evaluation
    Francisco A. Ramírez-Rivera, Néstor F. Guerrero-Rodríguez
    Sustainability Switzerland, 2024
    Solar radiation is a fundamental parameter for solar photovoltaic (PV) technology. Reliable solar radiation prediction has become valuable for designing solar PV systems, guaranteeing their performance, operational efficiency, safety in operations, grid dispatchment, and financial planning. However, high quality ground-based solar radiation measurements are scarce, especially for very short-term time horizons. Most existing studies trained machine learning (ML) models using datasets with time horizons of 1 h or 1 day, whereas very few studies reported using a dataset with a 1 min time horizon. In this study, a comprehensive evaluation of nine ensemble learning algorithms (ELAs) was performed to estimate solar radiation in Santo Domingo with a 1 min time horizon dataset, collected from a local weather station. The ensemble learning models evaluated included seven homogeneous ensembles: Random Forest (RF), Extra Tree (ET), adaptive gradient boosting (AGB), gradient boosting (GB), extreme gradient boosting (XGB), light gradient boosting (LGBM), histogram-based gradient boosting (HGB); and two heterogeneous ensembles: voting and stacking. RF, ET, GB, and HGB were combined to develop voting and stacking ensembles, with linear regression (LR) being adopted in the second layer of the stacking ensemble. Six technical metrics, including mean squared error (MSE), root mean squared error (RMSE), relative root mean squared error (rRMSE), mean absolute error (MAE), mean absolute percentage error (MAPE), and coefficient of determination (R2), were used as criteria to determine the prediction quality of the developed ensemble algorithms. A comparison of the results indicates that the HGB algorithm offers superior prediction performance among the homogeneous ensemble learning models, while overall, the stacking ensemble provides the best accuracy, with metric values of MSE = 3218.27, RMSE = 56.73, rRMSE = 12.700, MAE = 29.87, MAPE = 10.60, and R2 = 0.964.
  • An Overview of the Efficiency and Long-Term Viability of Powered Hydrogen Production
    Nestor F. Guerrero-Rodríguez, Daniel A. De La Rosa-Leonardo, Ricardo Tapia-Marte, Francisco A. Ramírez-Rivera, Juan Faxas-Guzmán, Alexis B. Rey-Boué, Enrique Reyes-Archundia
    Sustainability Switzerland, 2024
    This work studies the efficiency and long-term viability of powered hydrogen production. For this purpose, a detailed exploration of hydrogen production techniques has been undertaken, involving data collection, information authentication, data organization, and analysis. The efficiency trends, environmental impact, and hydrogen production costs in a landscape marked by limited data availability were investigated. The main contribution of this work is to reduce the existing data gap in the field of hydrogen production by compiling and summarizing dispersed data. The findings are expected to facilitate the decision-making process by considering regional variations, energy source availability, and the potential for technological advancements that may further enhance the economic viability of electrolysis. The results show that hydrogen production methods can be identified that do not cause significant harm to the environment. Photolysis stands out as the least serious offender, producing 0 kg of CO2 per kg of H2, while thermolysis emerges as the major contributor to emissions, with 20 kg of CO2 per kg of H2 produced.
  • Harmonic Distortion Study of a Photovoltaic Generator in a Microgrid under Disturbances
    Nestor F. Guerrero-Rodríguez, Rafael Omar Batista-Jorge, Francisco A. Ramírez-Rivera, Julio Ferreira, Robert Mercado-Ravelo, Abraham Manilla
    Energies, 2024
    This paper describes research on the harmonic-distortion capacity of a single-stage photovoltaic (PV) 3.68 kWp generator in a microgrid configuration. An overview of various harmonic compensator methods used in PV generators is presented to evaluate their advantages and disadvantages. Proportional-resonant (PR) structures with harmonic compensators (HCs) are designed, modeled, and validated through real-time tests. The modeling of harmonic compensation structures for a photovoltaic inverter using MATLAB/SIMULINK R2022a is explained in detail. The harmonic compensation capacity of a PV generator inverter is studied under voltage harmonics, grid frequency variation, and voltage unbalance. The contributions of this work are, firstly a bibliographic analysis of various strategies currently used for harmonic compensation in grid-connected inverters and secondly, a detailed explanation of the modeling of harmonic compensation structures using MATLAB/SIMULINK. Finally, a demonstration of the improvement in energy quality that results from using harmonic compensation techniques in photovoltaic generators in microgrid configurations affected by grid disturbances is performed. The obtained results show that harmonic compensation strategies based on resonant filters are a good alternative for the reduction of harmonic voltage distortion in the presence of grid disturbances such as frequency variation and voltage unbalance.
