Control secundario multi-agente para reconectar una microrred de convertidores formadores de red con la red principal
La resincronización es una característica fundamental para flexibilizar la operación de una microrred en su relación con la red principal. En la literatura se han propuesto estructuras de control secundario multi-agente ... -
Análisis modal de un compensador síncrono de 10kW con disco de inercia conectado a red
Este artículo explora el análisis modal de un compensador síncrono conectado a red mediante la estabilidad de pequeña perturbación. En las redes de energía renovable actuales, la disminución de la inercia y de la corriente ... -
Anomaly detection of a cooling water pump of a power plant based on its virtual digital twin constructed with deep learning techniques
This paper aims to explore the use of recent approaches of deep learning techniques for anomaly detection of potential failure modes in a cooling water pump working in a gas-combined cycle in a power plant. Two different ... -
Miniaturized top-metalized 3D-printed rectangular Dielectric Resonator Antenna
This paper introduces a novel top-metalized Dielectric Resonator Antenna (DRA). The inclusion of top metallization induces a modification in the boundary conditions, resulting in a frequency reduction in the fundamental ... -
Towards sustainability optimization in touristic route recommendation
While route recommendation plays a vital role in digital tourism services, conventional methods tend to be inherently complex, as they need to consider several constraints at once: user preferences, geographical and ... -
Variational Linearized Laplace Approximation for bayesian deep learning
The Linearized Laplace Approximation (LLA) has been recently used to perform uncertainty estimation on the predictions of pre-trained deep neural networks (DNNs). However, its widespread application is hindered by significant ... -
Impact of high penetration of grid forming converters in a large-scale power system
The stability of large-scale power systems is being challenged by the high penetration of converter interface generation (wind and solar photovoltaic).Synchronous generators must be committed to guarantee the stability of ... -
Robust optimal portfolio configuration of Renewable-based Virtual Power Plants for long-term planning
This paper proposes a robust optimal algorithm to determine the best portfolio configuration of Renewable-based Virtual Power Plants (RVPPs) over medium to long-term horizons. In this work, modifications to state-of-the-art ... -
System-wide benefits of renewable-based virtual power plants in island power systems
Renewable Energy Sources (RESs) have experienced significant growth in recent years. RES-based Virtual Power Plants (RVPPs) allow aggregating smaller RES-based Distributed Generators (DGs). This paper presents a system-wide ... -
Optimal bidding of renewable-based VPPs in energy and ancillary service markets
The tutorial discusses the dynamic analysis and operation of virtual power plants (VPPs), that is, clusters of generators located at different locations of the grid and providing coordinated services. The tutorial is ... -
The behind-the-scenes story of 2022 energy and inflationary crises: data, experiences and opinions of Spanish vulnerable households
The 2022 Russian invasion of Ukraine has caused a profound economic impact in Europe. In this new context of energy and inflationary crises, the EU and its Member States implemented different strategies to mitigate their ... -
Damping local and inter-area oscillations with synchronous compensators: a fundamental study
The increase in the penetration of inverter-based generation in current power systems is reducing their short circuit currents and inertia. Synchronous compensators are being proposed and installed to address those issues. ... -
