    Algorithm development for night charging electric vehicles optimization in big data applications
    (Elsevier B.V., 2017) Álvaro Hermana, Roberto ; Fraile Ardanuy, Jesús ; Merino, Julia
    In this paper a night charging method that optimizes the recharging process of electric vehicles (EVs) depending on hourly energy price in a peer to peer (P2P) energy trading system is presented. This algorithm determines how much energy should be recharged in the battery of each EV and the corresponding time slot to do it, avoiding the discontinuities in the charging process and considering the users' personal mobility constraints.

    Carbon-free electricity generation in Spain with PV–storage hybrid systems†
    (MDPI, 2022-06-29) Fraile Ardanuy, Jesús; Álvaro Hermana, Roberto; Castaño Solís, Sandra ; Merino, Julia
    Climate change motivated by human activities constitutes one of the main challenges of this century. To cut carbon emissions in order to mitigate carbon’s dangerous effects, the current energy generation mix should be shifted to renewable sources. The main drawback of these technologies is their intermittency, which will require energy storage systems to be fully integrated into the generation mix, allowing them to be more controllable. In recent years, great progress to develop an effective and economically feasible energy storage systems, particularly motivated by the recent rise of demand for electric transportation, has been made. Lithium-ion (Li-ion) battery prices have fallen near 90% over the past decade, making possible the affordability of electric vehicles and trans-forming the economics of renewable energy. In this work, a study on storage capacity demand previously presented as conference paper is expanded, including a deep analysis of the Spanish generation mix, the evaluation of the energy storage requirements for different low-carbon and carbon-free scenarios in Mainland Spain, and the calculation of the CO2 emissions’ reduction and the associated storage costs.

    Impacto de las políticas de autoconsumo y recarga del vehículo eléctrico en comunidades energéticas
    (Gobierno Vasco = Eusko Jaurlaritza, Departamento de Economía, Trabajo y Empleo = Ekonomia, Lan eta Enplegu Saila, 2021) Álvaro Hermana, Roberto ; Fraile Ardanuy, Jesús; Merino, Julia; Castaño Solís, Sandra
    El autoconsumo es una herramienta fundamental para integrar energías renovables y fomentar la participación activa de los consumidores en el sector energético. Para ello, la regulación del autoconsumo debe expandirse, incorporando figuras como el autoconsumo compartido, las comunidades energéticas, el almacenamiento y los vehículos eléctricos. En este artículo se presenta un problema de optimización del coste energético de una comunidad que considera diferentes políticas de autoconsumo compartido y gestión del vehículo eléctrico. El problema se aplica a una comunidad de energía compuesta por cinco consumidores domésticos para escenarios de uso del vehículo eléctrico con diferentes horarios de trabajo y consumos diarios. Los resultados muestran que las políticas involucradas tienen mayor impacto en el precio de la comunidad que el uso dado a los vehículos eléctricos.
