Abstract

The internet of things is undergoing rapid expansion, transforming diverse industries by facilitating device connectivity and supporting advanced applications. In the domain of energy production, internet of things holds substantial promise for streamlining processes and enhancing efficiency. This research introduces a comprehensive monitoring and energy management model tailored for the University of Cuenca's microgrid system, employing internet of things and ThingSpeak as pivotal technologies. The proposed approach capitalizes on intelligent environments and employs ThingSpeak as a robust platform for presenting and analyzing data. Through the integration of internet of things devices and sensors, the photovoltaic system's parameters, including solar radiation and temperature, are monitored in real time. The collected data undergo analysis using sophisticated models and are presented visually through ThingSpeak, facilitating effective energy management and decision making. The developed monitoring system underwent rigorous testing in a laboratory microgrid setup, where the photovoltaic system is interconnected with other generation and storage systems, as well as the electrical grid. This seamless integration enhances visibility and control over the microgrid's energy production. The results attest to the successful implementation of the monitoring system, highlighting its efficacy in improving the supervision, automation, and analysis of daily energy production. By leveraging internet of things technologies and ThingSpeak, stakeholders gain access to real-time data, enabling them to analyze performance trends and optimize energy resources. This research underscores the practical application of internet of things in enhancing the monitoring and management of energy systems with tangible benefits for stakeholders involved.

Abstract

[ES] El objetivo principal de esta Tesis Doctoral se centra en la presentación de soluciones de interconexión de red segura mediante la definición del diseño, estructura y funcionalidad de la protección eléctrica de los sistemas de interconexión de un nodo DC compacto multiterminal que alimenta ECVEs. La revisión bibliográfica/normativa ha revelado que hasta ahora no se ha prestado especial atención sobre la seguridad de sistemas interconectados en nodos de similares característica. De igual forma, tampoco se ha caracterizado el comportamiento de variables eléctricas del nodo en caso de faltas internas para nodos de este tipo (basados en convertidores reversibles). Conocer dicho comportamiento es clave para definir los requerimientos adecuados de protección eléctrica que garanticen la seguridad. Así, se ha definido un marco regulatorio unificado de requerimientos de protección eléctrica y configuración de sistemas de puesta a tierra aplicable a los sistemas de interconexión de red del nodo DC compacto multiterminal. [EN]The main objective of this Thesis is focused on the presentation of secure network interconnection solutions by defining the design, structure and functionality of the electric protection measurements of interconnection systems of a compact multiterminal DC node used to feed EVCSs. The literature/details about regulatory review has revealed that has not been paid special attention to the security of interconnected nodes in similar systems. Likewise, neither it has characterized the behavior of electrical variables for internal node to node failures of this type (based on reversible converters). Getting to know such behavior is key to defining suitable electrical protection requirements to ensure safety. Thus, it has been defined an unified regulatory framework for electrical protection requirements and an earthing system arrangement applicable to network interconnection of the compact multiterminal DC node.
