Addressing intra-area oscillations and frequency stability after DC segmentation of a large AC power system
En las últimas décadas, diversos acontecimientos han puesto de manifiesto que las oscilaciones electromecánicas constituyen un grave problema para los grandes sistemas eléctricos de corriente alterna (CA) interconectados. ... -
Islanded operation of distribution grid with high penetration of renewable energy sources
Renewable energy sources are being connected not only to transmission but also to distribution grids. Medium voltage distribution grids are meshed grids that are operated radially. Their reliability is determined by their ... -
Banking on mobiles. The role of digital epidemic effects and mobile money regulation in accelerating the uptake of financial services
Despite the accelerated mobile money adoption in emerging countries, financial inclusion levels remain well below the developed world, especially when advanced financial inclusion is considered. We argue that the adoption ... -
Climate-related credit risk: Rethinking the credit risk framework
Climate change poses a significant financial risk to economic agents, as well as a potential systemic risk threat due to uncertainty and non-linearity of the transition risks to a zero-carbon economy. This article conducts ... -
Ataque MitM a puntos de recarga AC
En este artículo presentamos un ataque MitM a puntos de recarga AC que permite controlar la carga del vehículo sin que el punto de recarga lo detecte. El ataque se ha llevado a cabo tanto en entorno de laboratorio como en ... -
Strategic plays in electricity markets: exploring gaming opportunities for demand under different settlement rules
Even when a market is cleared using optimal power flow calculations, ensuring dispatch feasibility, the settlement can be performed in different ways. In this paper, we consider three different types of settlement mechanisms ... -
Self-scheduling for a hydrogen-based virtual power plant in day-ahead energy and reserve electricity markets
This study presents an innovative optimization model for the self-scheduling of a hydrogen-based virtual power plant (H2-VPP) that aims to thrive in day-ahead energy and reserve markets. At its core, the model seeks to ... -
A comparative analysis of Cournot equilibrium and perfect competition models for electricity and hydrogen markets integration
The relationship between hydrogen and electricity has gained attention due to their interconnected roles in the energy transition. Existing joint electricity and hydrogen market models often overlook the dependence between ... -
Practical solutions to limit computational burden of UC in Island Power Systems
Unit commitment (UC) models used in real-life island power systems (IPSs) require complex modelling details and low execution times since they have to be launched repeated times for different assumptions and changing ... -
Electricity markets regulations: the financial impact of the global energy crisis
Amid the global energy crisis, we examine the impact of electricity market regulations in the European Union (EU). Pursuing an integrated EU elec-tricity market inadvertently heightened the interdependence between gas and ... -
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 ... -
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 ... -
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 ... -
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. ... -
A 3D-printed prototype of a miniaturized top-metalized rectangular Dielectric Resonator Antenna
This paper presents a 3D-printed prototype of 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 ... -
Performance of multi-agent secondary control for reconnecting a microgrid of grid-forming converters to the main grid
Electrical microgrids (MGs) are meant to make access to electricity more flexible. In this regard, they are required to work, alternatively, either connected to or disconnected from (forming an island) the main grid. ...
