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. ... -
New challenges in metrology for health: looking for reliable diagnosis in electrocardiography and blood pressure measurement
Improving awareness of the importance of measurements in the field of health is one of the objectives of the Spanish Metrology Centre (CEM). To achieve this, a health metrology laboratory has been set up to develop projects ... -
Emerging innovations in health metrology for diagnostic imaging
The Spanish National Metrology Center (CEM) is dedicated to advance the understanding of the essential role of measurements in the healthcare sector. CEM has created a laboratory in healthcare metrology to ensure the ... -
Probabilistic functional forecasting of Residual Demand Curves in electricity markets
Residual Demand Curves (RDCs) in electricity markets represent the market-clearing price as a function of the energy traded. Being able to generate accurate scenarios of these curves is critical for market agents' strategic ... -
Uncertain Decision Making: A Cooperative Agent Model For Flexible Renewable Energy Comunities
The paper proposes an innovative model for integrating energy communities within urban districts according to the smart cities paradigm. The approach developed contemplates the proactive participation of members of an ... -
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 ... -
A decentralized business model for integrating energy hubs into flexibility markets within renewable-based smart grids
This paper presents a bi-level model enabling energy hubs to release all their flexible capacities according to the price pulse in real-time flexibility markets. The Alternating Direction Method of Multipliers (ADMM) is ... -
Building bidding curves for an EV aggregator via stochastic adaptive robust optimization
This paper proposes a stochastic adaptive robust optimization approach to build the bidding curves of an aggregator in charge of a set of electric vehicles participating in the day-ahead electricity market. These bidding ... -
Sled tests for development of HIII CAE dummy certification method
Virtual testing has been used as complement to mechanical testing in consumer information programs such as European New Car Assessment Program (Euro NCAP) since 2009. Rapid expansion of virtual testing with additional load ... -
Preparing for virtual testing for crashworthiness: proposing a method for certifying ATD models for frontal crash assessments
In the Euro NCAP 2030 roadmap, Virtual Testing using the H3 adult ATD FE-models is planned to be implemented in the next phase. Certification of ATD models ensures that the virtual models can predict the response of the ... -
