Selective precipitation of ionosolv lignins: Replacing water with low enthalpy of vaporization antisolvents
Sara Villarino, Victoria Rigual, Beatriz García-Sánchez, Francisco Rodríguez, Julián García
Industrial Crops and Products, 2025
Ionic liquids (ILs) have shown promising results in the extraction of lignin in biorefineries using the Ionosolv process. Isolating lignin from the IL-lignin solution to enable IL recycling is a critical step for the viability of this technology. The use of water as a lignin antisolvent is a well-established practice. However, the subsequent distillation of the antisolvent inevitably results in considerable energy expenditure due to the high enthalpy of vaporization of water. In this context, the substitution of water by solvents with low enthalpy of vaporization has been investigated. Lignin was extracted from eucalyptus wood using the IL 2-hydroxyethylammonium acetate or monoethanolammonium acetate ([MEA][OAc]). Alternative antisolvents tert-butanol, 2-propanol, and 1-butanol were tested for lignin precipitation and their energy recovery cost, was calculated and compared with the base case (water as antisolvent). The recovered lignins were characterized by a combination of techniques, including gel permeation chromatography (GPC), two-dimensional nuclear magnetic resonance (2D‐NMR),and thermogravimetric analysis (TGA), with the objective of elucidating the extracted lignin chemical structure and thermal stability. Lignins precipitated with alcohols had higher average molecular weights and lower polydispersity indexes compared to those precipitated with water. Furthermore, lignins precipitated with alcohols exhibited remarkable thermal stability at high temperatures and were characterised by an abundance of β-O-4’ linkages and S units. Consequently, this work proposes an alternative approach to the separation of ionosolv lignins from ILs with lower associated energy consumptions, while simultaneously delivering lignins with enhanced characteristics in comparison to the conventionally accepted Ionosolv process.
Multi-objective optimization of autohydrolysis of Prunus avium stones for hemicellulose extraction, obtaining high-value products
Beatriz García-Sánchez, Victoria Rigual, Juan C. Domínguez, M. Virginia Alonso, Mercedes Oliet, Francisco Rodriguez
International Journal of Biological Macromolecules, 2025
Prunus avium stones represent an agro-industrial waste with considerable potential to produce value-added bioproducts. This study examines the impact of temperature, time, and liquid-solid ratio on the autohydrolysis of Prunus avium shell stones (CSS) to ascertain their effect on hemicellulose extraction and on subsequent production of a cellulose- and lignin-rich solid. This analysis employed a central composite design of experiments. Furthermore, the phenolic compound content of the liquid phases and their antioxidant capacity were determined. Subsequently, a multi-objective optimization was conducted to maximize the removal of hemicellulose from CSS, producing a solid with high cellulose and lignin content while minimizing cellulose loss through solubilization in the liquid phases. The results of the multi-objective optimization demonstrated that a temperature of 185 °C, a reaction time of 65 min, and a liquid-solid ratio of 8:1 ( w /w) were optimal for the removal of hemicellulose (88.12 %), while maintaining a solid fraction rich in cellulose and lignin. Furthermore, the resulting liquors contained xylooligosaccharides (17.73 % recovery) and phenolic compounds (18.91 mg GAE/g CSS) and showed antioxidant capacity (9.69 TEAC/g CSS). This research contributes to advancing sustainable agro-industrial waste valorization and the circular economy by investigating xylooligosaccharide and phenolic compound extraction as raw materials for other industries. • Multi-objective optimization of hemicelluloses and phenolic compounds extraction. • Effects of temperature, time, and liquid-solid ratio on Prunus Avium stone autohydrolysis. • Achieved 90 % hemicellulose extraction under optimal conditions. • Produced cellulose and lignin-rich solid for subsequent fractionation. • Autohydrolysis liquors demonstrated antioxidant activity and high phenolic content.
Design and implementation of multiprotocol framework for residential prosumer incorporation in flexibility markets
Miguel Gayo-Abeleira, F.J. Rodríguez, Carlos Santos, Ying Wu, Yanpeng Wu, Juan C. Vasquez, Josep M. Guerrero
Internet of Things Netherlands, 2023
The growth of distributed renewable energy in the electrical grid presents challenges to its stability and quality. To address this at the local level, flexibility energy strategies emerge as an innovative technique. However, managing these strategies in residential areas becomes complex due to the unique characteristics of each prosumer. A major challenge lies in managing communication among diverse devices with different protocols. To address these issues, a comprehensive framework is designed and implemented to facilitate prosumers' integration in flexibility strategies, addressing communication at various levels. The effectiveness of the proposed framework is demonstrated through its implementation in a real smart home environment with diverse devices. The framework enables seamless integration and communication between IoT devices and IEC 61850-compliant power devices. This research presents a novel approach to address the challenges of managing flexibility strategies in residential areas, providing a practical solution for prosumers to actively participate in optimizing energy consumption and enhancing the stability and quality of the electricity system amidst the growing integration of distributed renewable energy.
Intra-day solar power forecasting strategy for managing virtual power plants
Guillermo Moreno, Carlos Santos, Pedro Martín, Francisco Javier Rodríguez, Rafael Peña, Branislav Vuksanovic
Sensors, 2021
Solar energy penetration has been on the rise worldwide during the past decade, attracting a growing interest in solar power forecasting over short time horizons. The increasing integration of these resources without accurate power forecasts hinders the grid operation and discourages the use of this renewable resource. To overcome this problem, Virtual Power Plants (VPPs) provide a solution to centralize the management of several installations to minimize the forecasting error. This paper introduces a method to efficiently produce intra-day accurate Photovoltaic (PV) power forecasts at different locations, by using free and available information. Prediction intervals, which are based on the Mean Absolute Error (MAE), account for the forecast uncertainty which provides additional information about the VPP node power generation. The performance of the forecasting strategy has been verified against the power generated by a real PV installation, and a set of ground-based meteorological stations in geographical proximity have been used to emulate a VPP. The forecasting approach is based on a Long Short-Term Memory (LSTM) network and shows similar errors to those obtained with other deep learning methods published in the literature, offering a MAE performance of 44.19 W/m2 under different lead times and launch times. By applying this technique to 8 VPP nodes, the global error is reduced by 12.37% in terms of the MAE, showing huge potential in this environment.
Turning base transceiver stations into scalable and controllable dc microgrids based on a smart sensing strategy
Miguel Tradacete, Carlos Santos, José A. Jiménez, Fco Javier Rodríguez, Pedro Martín, Enrique Santiso, Miguel Gayo
Sensors Switzerland, 2021
This paper describes a practical approach to the transformation of Base Transceiver Stations (BTSs) into scalable and controllable DC Microgrids in which an energy management system (EMS) is developed to maximize the economic benefit. The EMS strategy focuses on efficiently managing a Battery Energy Storage System (BESS) along with photovoltaic (PV) energy generation, and non-critical load-shedding. The EMS collects data such as real-time energy consumption and generation, and environmental parameters such as temperature, wind speed and irradiance, using a smart sensing strategy whereby measurements can be recorded and computing can be performed both locally and in the cloud. Within the Spanish electricity market and applying a two-tariff pricing, annual savings per installed battery power of 16.8 euros/kW are achieved. The system has the advantage that it can be applied to both new and existing installations, providing a two-way connection to the electricity grid, PV generation, smart measurement systems and the necessary management software. All these functions are integrated in a flexible and low cost HW/SW architecture. Finally, the whole system is validated through real tests carried out on a pilot plant and under different weather conditions.
Integration of Blockchain with IEC 61850 for Internal Management of Microgrids
M. Gayo, F. J. Rodriguez, C. Santos, P. Martin, J.A. Jimenez
IEEE International Symposium on Industrial Electronics, 2020
This paper proposes a local management approach for a microgrid (MG) which comprises a great variety of heterogeneous prosumers, connected to the main grid at a single point. The management system obtains a fair division of costs billed by the utility through the design of a local energy market within the MG. This local market relies on blockchain (BC) technology with the aim of guaranteeing the veracity and immutability of the data and automating the transactions. Likewise, the energy-related prosumer data is obtained using IEC 61850 protocol running on the BC. The veracity of the electrical parameters is, therefore, effectively guaranteed, since the prosumers do not have to introduce the data in the BC. This, in turn, makes the system compatible with any device irrespective of the manufacturer implementing the IEC 61850 standard. The purpose of this management strategy is twofold: firstly, competitive prices can be offered to the MG participants in terms of both sales and acquisitions in comparison to those set by the conventional grid utilities; and secondly the MG becomes less dependent on the grid and less unpredictable on account of the internal energy exchanges.
A day-ahead irradiance forecasting strategy for the integration of photovoltaic systems in virtual power plants
Guillermo Moreno, Pedro Martin, Carlos Santos, Francisco J. Rodriguez, Enrique Santiso
IEEE Access, 2020
Encouraged by the considerable cost reduction, small-scale solar power deployment has become a reality during the last decade. However, grid integration of small-scale photovoltaic (PV) solar systems still remains unresolved. High penetration of Renewable Energy Sources (RESs) results in technical challenges for grid operators. To address this, Virtual Power Plants (VPPs) have been defined and developed to manage distributed energy resources with the aim of facilitating the integration of RESs. This paper introduces a hybrid irradiance forecasting approach aimed at facilitating the integration of PV systems into a VPP, especially when a historical irradiance dataset is exiguous or non-existent. This approach is based on Artificial Neural Networks (ANNs) and a novel similar hour-based selection algorithm, has been tested for a real PV installation, and has been validated also considering irradiance measurements from an aggregation of ground-based meteorological stations, which emulate the nodes of a VPP. Under a reduced historical dataset, the results show that the proposed similar hour-based method produces the best forecasts with regard to those obtained by the ANN-based approach. This is particularly true for one-month and two-month datasets minimizing the mean error by 16.32% and 9.07% respectively. Finally, to demonstrate the potential of the proposed approach, a comparative analysis has been carried out between the hybrid method and the most used benchmarks in the literature, namely, the persistence method and the method based on similar days. It has been demonstrated conclusively that the proposed model yields promising results regardless the length of the historical dataset.
Model-based latency compensation for network controlled modular multilevel converters
Tomás P. Corrêa, Francisco J. Rodríguez, Emilio J. Bueno
Electronics Switzerland, 2019
The use of an internal digital communication network enhances the scalability, implementation and maintenance of Modular Multilevel Converters (MMC). However, it also introduces delays that limit the sampling frequency and the controller dynamic performance. In this paper, we propose a model-based predictor to compensate for the loop delay and overcome these limitations. Two benefits of this approach are possible: either designers can increase the sampling rate and control performance or employ a slower communication protocol/technology. In this paper, we present the mathematical description of the model-based predictor, assess the parameter sensitivity, and show matching simulation and experimental results that validate it. As constraints introduced by the use of digital communications are overcome, the results achieved encourage engineers to adopt a network into the design of Modular Multilevel Converters.
Communication aspects in the distributed control architecture of a modular multilevel converter
Tomas P. Correa, Luis Almeida, Francisco J. Rodriguez
Proceedings of the IEEE International Conference on Industrial Technology, 2018
Several authors researched on the use of digital communications in the control of Modular Multilevel Converters, but, in our opinion, three characteristics of this solution need more discussion: transmission media, synchronization accuracy, and network topology. In this paper, we also address the gap of modeling the communications with more details. For this, we propose a simple cosimulation strategy that relies on the fact that the control and power circuits have no real-time influence in the operation of the communication network. We present simulations with OMNeT++ and Matlab/Simulink to demonstrate the importance of a more detailed modeling of the system.
