Peyghami, S. (author), Palensky, P. (author), Blaabjerg, Frede (author)Renewable energy resources are becoming the dominating element in power systems. Along with de-carbonization, they transform power systems into a more distributed, autonomous, bottom-up style one. We speak of Smart Grid and Microgrid when distributed energy resources take over. While being a means to improve technical and financial efficiency,...journal article 2020

Alavi, F. (author), van de Wouw, N. (author), De Schutter, B.H.K. (author)A microgrid in the islanded mode is considered where a fleet of fuel cell cars is used as a distributed power generation system. The objective of the proposed control system is to minimize the operational cost of the system, subject to the physical and operational constraints of the system. In order to deal with uncertainty in the prediction...journal article 2020

Mlecnik, E. (author), Parker, James (author), Ma, Zheng (author), Corchero, Cristina (author), Knotzer, Armin (author), Pernetti, Roberta (author)European energy policies call for an increased share of renewable energy sources and a more active role of the energy consumer. This is facilitated by, amongst others, buildings becoming energy flexible hubs, supporting smart energy grids with demand response strategies. While there is abundant technical research in this field, the related...journal article 2020

Hennig, R.J. (author), Jonker, Martijn (author), Tindemans, Simon H. (author), De Vries, Laurens (author)Residential distribution networks in Europe are undergoing rapid changes. As high-power flexible loads, such as electric vehicle (EV) chargers, become more prevalent, the risk of network congestion increases. This is exacerbated by tariff structures which do not give incentives to limit simultaneous power consumption. Network charges in this...conference paper 2020
