    Impact of self-consumption and electric vehicle recharging policies on energy communities
    (2021) Alvaro-Hermana, Roberto; Fraile-Ardanuy, Jesús; Merino, Julia; Castano-Solis, Sandra; Tecnalia Research & Innovation
    Self-consumption is a key element to integrate renewable energies and foster consumer participation in the energy sector. To expand it, self-consumption regulation needs to incorporate policies such as shared self-consumption, energy communities, storage and electric vehicles. In this article, an optimization problem for the total cost of an energy community considering different self-consumption and electric vehicle management policies is presented. The problem is applied to a set of electric vehicle usage scenarios with diverse work schedules and daily consumptions. Results show that the involved policies have a greater impact on the community’s energy cost than the usage of the electric vehicles.||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.

    Shared Self-Consumption Economic Analysis for a Residential Energy Community
    (IEEE, 2019-09) Alvaro-Hermana, Roberto; Merino, Julia; Fraile-Ardanuy, Jesus; Castano-Solis, Sandra; Jimenez, David; Tecnalia Research & Innovation
    Self-consumption is a growing public demand in an energy environment with growing electricity costs and decreasing photovoltaic installation costs. Shared self-consumption is an imperative aspect for bringing self-consumption into Multi-Family Residential Buildings (MRB), where most families live. Nevertheless, current legislation in most countries does not consider shared self-consumption or does not exploit its full potential; such is the case of Spain or Portugal. This paper will present a novel optimization problem for studying the economics of a shared self-consumption installation in a MRB (composed of five family demands, a PV installation and a battery) with the aim of reducing the total bill of the MRB during an entire year. The impact on energy communities of two different types of energy policies is analysed: the remuneration scheme for the surplus energy (net metering, net billing, and exclusive self-consumption policies) and the regulation for shared self-generated energy (demand-dependent, proportional output and no sharing). It is found that the regulation for the sharing energy can be more important that the remuneration scheme, which has been the traditional target of the self-consumption policy.
