El papel de la electricidad en la transición energética: de la descarbonización del sector eléctrico a la electrificación de la economía
Miércoles 7 de julio | 10:00 – 11:00
Este modelo energético tiene fecha de caducidad por la limitación de los recursos, su concentración geográfica y su impacto ambiental. Durante mucho tiempo se ha retrasado el cambio de modelo por la falta de tecnologías alternativas pero en el siglo XXI ya disponemos de las herramientas necesarias para acabar con la dependencia de los combustibles fósiles:
Por una parte la energía hidráulica, eólica y solar permitirán que países como España puedan producir más del 75% de su electricidad con fuentes renovables.
Por otro lado los vehículos eléctricos, la bomba de calor, los usos directos de la electricidad y el hidrógeno verde harán posible que usemos la electricidad renovables en todos los ámbitos de nuestra vida.

High Reporting Rate Measurements for Smart[er] Grids
Viernes 9 de julio | 10:45 – 11:45
There are several applications where synchronized data received with high reporting rate has to be used together with aggregated data from measurement equipment having a lower reporting rate (complying with power quality data aggregation standards) and the accompanying question is how adequate are the energy transfer models in such cases. For example, state estimators need both types of measurements: the so-called “classical” one, adapted for a de facto steady-state paradigm of relevant quantities and the “modern” one, i.e. with fewer embedded assumptions on the variability of same quantities. Another example is given by emerging active distribution grids operation, which assumes higher variability of the energy transfer and consequently a new model approximation for its characteristic quantities (voltages, currents) is needed. Such a model is required not only in order to be able to correctly design future measurement systems but also for better assessing the quality of existing “classical” measurements, still in use for power quality improvement, voltage control, frequency control, network parameters’ estimation etc.
The main constraint so far is put by the existing standards where several aggregation algorithms are recommended, with specific focus on the information compression. The further processing of rms values (already the output of a filtering algorithm) results in significant signal distortion.
Presently there is a gap between (i) the level of approximation used for modeling the current and voltage waveforms which is implicitly assumed by most of the measurement devices deployed in power systems and (ii) the capabilities and functionalities exhibited by the high fidelity, high accuracy and high number of potential reporting rates of the newly deployed synchronized measurement units.
The talk will address:
The measurement paradigm in power systems.
– System inertia, real time and steady-state.
– Instrument transformers; limited knowledge on the infrastructure.
– PQ, SCADA and PMUs.
– Power system state estimation; WAMCS.
– IEDs, PMUs, microPMUs.
– Time-stamped versus synchronized measurements.
Measurement channel quality and models for energy transfer.
– Voltage and frequency variability; rate of change of frequency.
– The steady-state signal and rapid voltage changes (RVC); rms-values reported with 100 frames/s.
– Measurement data aggregation; filtering properties.
– Time-aggregation algorithms in the PQ framework.
– Statistical approaches.
Applications and challenges.
– Communication channel requirements; delay assessment in WAMCS.
– Smart metering with high reporting rate (1s).
The presentation provides an overview of these techniques, with examples from worldwide measurement solutions for smart grids deployment.
