Item Coordination of the charging of electric vehicles using a multi-agent system(2013-12) Papadopoulos, Panagiotis; Jenkins, Nick; Cipcigan, Liana M.; Grau, Inaki; Zabala, Eduardo; Tecnalia Research & InnovationAn agent-based control system that coordinates the battery charging of electric vehicles in distribution networks is presented. The objective of the control system is to charge the electric vehicles at times of low electricity prices within distribution network technical constraints. Search techniques and neural networks are used for the decision making of the agents. The ability of the control system to work successfully when the distribution network is operated within its loading limits and when the loading limits are violated is demonstrated through experimental validation.Item Large-scale demonstration of TSO–DSO coordination: the CoordiNet Spanish approach: the CoordiNet Spanish approach(2020) Utrilla, F. David Martín; Davi-Arderius, Daniel; Martínez, Alberto Gil; Chaves-Ávila, José Pablo; Arriola, Inés Gómez; POWER SYSTEMSThe necessary energy transition to decarbonise power systems is leading to increasingly important challenges for the operation of power systems. On the one hand, the intermittent nature of renewable generation requires system operators to procure system services in larger volumes than in the past. On the other hand, the growing penetration of medium- and small-scale, flexible demand and storage systems in distribution networks might result in congestions or voltage problems in this grid level, but these resources could potentially offer system services, if they are aggregated effectively and there is appropriate coordination between transmission system operators (TSOs), distribution system operators (DSOs) and aggregators. Therefore, an interesting topic to be analysed is whether distributed energy resources can replace traditional generation in the provision of system services, how this replacement will affect the system operators' roles and how to improve the coordination between TSOs and DSOs. The CoordiNet project aims at demonstrating, through different TSO–DSO coordination schemes, options for providing system services with flexible resources located at different voltage levels. This study shows the Spanish demonstrators, in which REE (TSO) and the two largest DSOs, i.e. e-distribución and i-DE participate, as well as IIT Comillas and Tecnalia, among several European partners.Item Management of electric vehicle battery charging in distribution networks with multi-agent systems(2014-05) Grau Unda, Iñaki; Papadopoulos, Panagiotis; Skarvelis-Kazakos, Spyros; Cipcigan, Liana M.; Jenkins, Nick; Zabala, Eduardo; Tecnalia Research & InnovationAn agent-based control system that manages the battery charging of electric vehicles in power distribution networks is presented. The electric vehicle battery charging schedules are calculated according to electricity prices and distribution network technical constraints. The design of the multi-agent system is described. The real-time operation of the multi-agent system was demonstrated in a test-bed of a laboratory micro-grid.
