It aims at high flexibility using a modular approach with a common hardware for most of the tasks. The proposed framework for laboratory scale microgrid addresses the requirements for teaching and research. This objective is attained with a reconfigurable power electronics stage, used for test and design of new topologies. The experimental framework also allows testing algorithms at different levels in the hierarchical control structure, while giving access to emulation and simulation of elements commonly found in microgrids and to low-level programming of communication protocols for studying the communications channel. The processing unit in each module, called local controller in the paper, uses a high performance digital signal processor (DSP). This processing unit allows reconfiguration of each module, to assume any of the tasks in the microgrid, i.e. controllable loads, storage, wind, photovoltaic generation, etc. The proposed hardware was tested as a simulator/emulator of the different subsystems. The communications with a microgrid central controller (MCC) is provided with standard embedded processors, capable of implementing the communication protocols suitable for micro-grid environments.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN  Este artículo presenta una propuesta de un banco de pruebas de microrredes para uso en laboratorio. El objetivo es proporcionar alta flexibilidad utilizando un enfoque modular con un hardware común para la mayoría de las tareas. El marco experimental propuesto para microrredes a escala de laboratorio proporciona los requisitos para enseñanza e investigación. Esto se logra con una etapa de electrónica de potencia reconfigurable, para pruebas y diseños de nuevas topologías. Permite probar algoritmos en los distintos niveles de la estructura jerárquica de la microrred. Da acceso a la emulación y simulación de elementos encontrados comúnmente en una microrred y a la programación de bajo nivel de los protocolos de comunicación para estudiar el canal de comunicación. La unidad de procesamiento en cada módulo, llamado controlador local, utiliza un procesador digital de señales de alto rendimiento (DSP). Esta unidad de procesamiento permite la reconfiguración de cada módulo para asumir cualquier tarea en la microrred; es decir, como cargas controlables, almacenamiento de energía, generación eólica, generación fotovoltaica, etc. El hardware propuesto se probó operando como emulador de los diferentes subsistemas. Las comunicaciones con un controlador central microrred (MCC) se realizan mediante procesadores integrados estándar, capaces de implementar los protocolos de comunicación adecuados para ambientes de microrred.]]></p></abstract>
