Dimitrovski, T. (author), Bergman, T. (author), Zuraniewski, P. (author)The use of Machine Learning in many control and management processes is rising fast. This is especially true for the management of cloud native applications and for anomaly detection in cyber-security mechanisms. However, it has been shown that ML is an attack surface on its own, especially when the attack is performed by another ML system....conference paper 2023

Giraldo, J.S. (author), Bañol Arias, N. (author), Vergara, P.P. (author), Vlasiou, M. (author), Hoogsteen, G. (author), Hurink, J.L. (author)This paper introduces a AC stochastic optimal power flow (SOPF) for the flexibility management of electric vehicle (EV) charging pools in distribution networks under uncertainty. The AC SOPF considers discrete utility functions from charging pools as a compensation mechanism for eventual energy not served to their charging tasks. An application...article 2023

van der Holst, B. (author), Verhoeven, G. (author), Nguyen, P. (author), Kok, K. (author), Emde, M.F. (author), Nutma, J.S. (author), la Fleur, S. (author)The increasing number of full-electric heat pumps (HPs) could potentially lead to congestion issues in future distribution grids. However, most modern HPs have the possibility to reduce demand during expected congestion events in a flexible manner. This study proposes a new approach for characterizing the potential downward flexibility of full...conference paper 2023
