Distribution System Operators face a challenging
environment largely affected by the ever-growing
integration of Distributed Energy Resources. Especially,
Electric Vehicles have a rapidly growing presence in the
distribution grids, being both a challenge, but also an
enabler for active network management. This work
analyses the operation of charging infrastructures in
coordination with the DSO in the context of the FEVER
project. The objective of the project is to exploit control of
power flow through DC/AC converters towards demand
management and voltage compensation. The paper
describes the different modules required to coordinate this
operation in a flexibility market context. DSO support
tools have been developed to forecast possible critical
events and prepare a mitigation plan leveraging flexibility.
Response to this flexibility demand is covered by Vehicleto-Grid charging stations, equipped with DC converters,
capable of implementing flexibility strategies

This work addresses the management of charging infrastructure to cope with the problem of congestion in the electric grid by exploiting electric vehicle (EV) flexibility. Benefits of scheduling charging sessions based on user profiles is compared with two traditional methods for limiting charging power: using static a dynamic control signal. The user profile concept is a classification strategy that consists in assigning a label to every EV user, referring to a connection pattern in the daily use of the charging infrastructure. The study analyses pros and cons of these three approaches and highlight the advantages of demand-response programs based on the user profiles. Thus, while limiting the power of charging sessions with a static signal causes a rebound effect, using a dynamic signal requires impacting a high amount of sessions. Scheduling (i.e. postponing) the charging sessions associated to profiles with low-variance provides a higher efficiency of the demand-response program since the same objective (i.e. peak demand reduction to 350 kW) is achieved with a lower number of participating sessions (40% fewer than limiting charging power with dynamic signal)

Synergies between multiple energy vectors can support decarbonization of local energy islands and, at the same time, relieve stress from the electricity grid. Multi-vector energy systems offer flexibility to integrate variable and economic local energy generation. However, the implementation and operation of multi-vector energy systems face technical, societal and business-related challenges. This paper identifies these challenges and proposes different tools to tackle them. These tools are to be developed in the E-LAND project funded by European Union under the H2020 scheme. Special focus of the paper is on developing a method for optimal planning and operation of multi-vector grid considering robustness. Another novelty of technical tool lies in making scheduling decisions on long-term and short-term storage considering demand response as flexibility resource. By combining technological, societal and business tools, the project expects to create multi-vector energy systems accepted by citizens and with viable business model

Postprandial glucose fluctuations are a challenge to daytime
closed-loop control1,2 in type 1 diabetes (T1D).
It is predicted that the high number of missed meal boluses
experienced during insulin pump therapy3 will carry over to
artificial pancreas therapy.
Therefore, a means to reduce poor outcomes due to
unannounced meals must be developed.
The aim of this study is to implement an algorithm to detect
meals using data from a continuous glucose monitor (CGM)
and the insulin delivered to the subject
