- PublicationCurrent challenges and future trends in the field of communication architectures for microgrids(Elsevier, 2018) Marzal-Romeu, Silvia; Salas-Puente, Robert Antonio; González Medina, Raúl; Garcerá Sanfeliú, Gabriel; Figueres Amorós, Emilio; Dpto. de IngenierÃa Electrónica; Escuela Técnica Superior de IngenierÃa del Diseño; Escuela Técnica Superior de IngenierÃa Industrial; Grupo de Sistemas Electrónicos Industriales; Ministerio de EconomÃa y Competitividad; European Regional Development Fund[EN] The concept of microgrid has emerged as a feasible answer to cope with the increasing number of distributed renewable energy sources which are being introduced into the electrical grid. The microgrid communication network should guarantee a complete and bidirectional connectivity among the microgrid resources, a high reliability and a feasible interoperability. This is in a contrast to the current electrical grid structure which is characterized by the lack of connectivity, being a centralized-unidirectional system. In this paper a review of the microgrids information and communication technologies (ICT) is shown. In addition, a guideline for the transition from the current communication systems to the future generation of microgrid communications is provided. This paper contains a systematic review of the most suitable communication network topologies, technologies and protocols for smart microgrids. It is concluded that a new generation of peer-to-peer communication systems is required towards a dynamic smart microgrid. Potential future research about communications of the next microgrid generation is also identified.

- PublicationPower Management of the DC Bus Connected Converters in a Hybrid AC/DC Microgrid Tied to the Main Grid(MDPI AG, 2018) Salas-Puente, Robert Antonio; Marzal-Romeu, Silvia; González Medina, Raúl; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel; Dpto. de IngenierÃa Electrónica; Escuela Técnica Superior de IngenierÃa del Diseño; Escuela Técnica Superior de IngenierÃa Industrial; Grupo de Sistemas Electrónicos Industriales; Ministerio de EconomÃa, Industria y Competitividad[EN] In this paper, a centralized control strategy for the efficient power management of power converters composing a hybrid AC/DC microgrid is explained. The study is focused on the converters connected to the DC bus. The proposed power management algorithm is implemented in a microgrid central processor which is based on assigning several operation functions to each of the generators, loads and energy storage systems in the microgrid. The power flows between the DC and AC buses are studied in several operational scenarios to verify the proposed control. Experimental and simulation results demonstrate that the algorithm allows control of the power dispatch inside the microgrid properly by performing the following tasks: communication among power converters, the grid operator and loads; connection and disconnection of loads; control of the power exchange between the distributed generators and the energy storage system and, finally, supervision of the power dispatch limit set by the grid operator.

- PublicationDiseño e implementación de un interfaz HMI basado en ARM Cortex M4F para el testeo de inversores fotovoltaicos(Universitat Politècnica de València, 2016-05-17) Combarros Hernández, Gonzalo; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel; Dpto. de IngenierÃa Electrónica; Escuela Técnica Superior de IngenierÃa Industrial; Grupo de Sistemas Electrónicos Industriales[EN] The aim of this project is to develop a touch interface to monitor all possible devices involved into a microgrid developed by GSEI. Additionally, the platform also has to monitor a prototype of a solar panel emulator and a platform test of the microgrid developed in parallel with this work. The study starts with a hardware description of the base board designed around the touchscreen with the Tiva C Launchpad evaluation board, which is the brain of the system. Then, it is described the design made for an additional daughter board which provides a bridge between the monitor platform and de input channels from the microgrid. With regards to the software part: it shows one by one all the panels and functions implemented inside the touch interface, as well as a variety of internal functions that ensures its smooth operating. Eventually, there have been carried out a couple of tests to validate the developed communications over ModBus. The first test validates that the touchscreen is able to govern the test platform, monitoring its operation too. The second one verifies the input channels from the microgrid are able to send and receive ModBus frames.
- PublicationGestión eficiente de los convertidores de potencia conectados al bus DC de una Microrred hÃbrida de generación distribuida(Universitat Politècnica de València, 2019-03-22) Salas Puente, Robert Antonio; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel; Dpto. de IngenierÃa Electrónica; Escuela Técnica Superior de IngenierÃa Industrial; Grupo de Sistemas Electrónicos Industriales[ES] Dos aspectos crÃticos en la operación de una microrred son las estrategias de control y gestión de potencia implementadas, las cuales son esenciales para proporcionar su buen funcionamiento. La aplicación adecuada de dichas estrategias permite compensar los desequilibrios de potencia causados por la discontinuidad de la generación y de la demanda de energÃa en las microrredes. En este sentido, el objetivo global de estas estrategias de gestión es equilibrar adecuadamente el flujo de potencia en la microrred, mediante la aplicación de diferentes algoritmos que permiten cumplir con los criterios de estabilidad, protección, balance de potencia, transiciones, sincronización con la red y gestión adecuada de la microrred. En el caso de microrredes de pequeña escala de potencia con bajo número de generadores y sistemas de almacenamiento distribuidos, las estrategias de control centralizado ofrecen un alto nivel de flexibilidad para lograr funcionalidades avanzadas en la microrred y una adecuada distribución de la potencia entre los convertidores que la conforman. Esta tesis se ha enmarcado en el contexto de algoritmos de gestión centralizada de potencia de una microrred de generación distribuida en modo conectado a red. Los algoritmos presentados se pueden aplicar a los convertidores de potencia conectados al bus DC de una microrred AC/DC hÃbrida o en una microrred de DC, donde el despacho de potencia es observado y gestionado por un controlador central. Este último adquiere datos del sistema mediante una infraestructura de comunicaciones y estima la potencia que gestionará cada uno de los convertidores de potencia, sistemas de almacenamiento y cargas en funcionamiento. En este estudio se muestra la validación experimental de las estrategias de gestión aplicadas en la microrred desde el enfoque del comportamiento de los convertidores de potencia, de las baterÃas y las cargas ante dicha gestión. Se verifica la estabilidad de la microrred sometiendo a los convertidores a diferentes escenarios de funcionamiento. Estos escenarios pueden ser fluctuaciones en la irradiación, la demanda, el estado de carga de las baterÃas, los lÃmites máximos de exportación/importación de potencia desde/hacia la microrred hacia/desde la red principal y de la tarifa eléctrica. Adicionalmente, se propone un sistema de almacenamiento de energÃa en baterÃas encargado de mantener el equilibrio de potencia en el bus de DC de la microrred que permite aprovechar las fuentes de generación renovables presentes en la microrred y maximizar el tiempo de servicio de las baterÃas mediante la aplicación de un algoritmo de carga de las baterÃas. Este último se ajusta al procedimiento de carga especificado por el fabricante, estableciendo las tasas de carga en función de los escenarios en que la microrred se encuentre. El procedimiento de carga en las baterÃas es fundamental para garantizar las condiciones adecuadas de operación de las mismas, ya que toman en consideración los parámetros establecidos por el fabricante, como son: tasas de carga/descarga, tensión máxima de carga, temperaturas de operación, etc.
- PublicationPerformance Evaluation of the B4 Topology for Implementing Grid-Connected Inverters in Microgrids(MDPI AG, 2024-05) Torán Mort, Enric; Liberos Mascarell, MarÃa Antonia; Patrao Herrero, Iván; González Medina, Raúl; Garcerá Sanfeliú, Gabriel; Figueres Amorós, Emilio; Dpto. de IngenierÃa Electrónica; Escuela Técnica Superior de IngenierÃa del Diseño; Escuela Técnica Superior de IngenierÃa Industrial; Grupo de Sistemas Electrónicos Industriales; AGENCIA ESTATAL DE INVESTIGACION; Ministerio de Ciencia e Innovación[EN] The B4 topology is an interesting alternative to the conventional B6 inverter due to its reduced number of parts and lower cost. Although it has been widely used in the past, especially in low-power motor drive applications, its application as a grid-connected inverter is an open area of research. In this regard, this paper analyses the feasibility of the B4 inverter topology for grid-connected applications. A versatile 7 kW inverter prototype, which may be configured as B4 and B6, was built, allowing for a comprehensive evaluation of the performance of both topologies. Through an analytical study and experimental tests, the performance of the B4 and B6 topologies was comparatively evaluated in terms of efficiency, total harmonic distortion of line currents, current unbalance, cost, and mean time between failures. The study was carried out in the context of microgrid systems, highlighting their role in the integration of renewable energy and distributed generation.
