Crompvoets, JPA (author)Over the past decade, a new concept for the power grid called the smart grid emerged, to enable two way energy transport and communication. With this new smart grid architecture many opportunities for control methods arise. While this can improve the efficiency of the power grid, all these methods require communication, which is a limited...master thesis 2021

ten Boske, Lisette (author)In the future, the energy supply will primarily consist of energy from renewables, which makes energy producers and grid operators fear that grid security and reliability could be threatened. On top of a more fluctuating supply, energy demand is also expected to increase in the coming years, especially if heating will be electrical when gas is...master thesis 2021

Logeman, Joris (author)Climate change is one of the biggest challenges of this time. One of the necessary changes to combat this challenge is a shift from conventional power resources, such as coal and natural gas, to large scale deployment of renewable resources, such as wind and solar power. However, renewable energy resources are volatile because they depend on the...master thesis 2021

van Leeuwen, C.J. (author)In this thesis I research the ability of groups of agents to organize their collective behavior, without any human intervention. Using a framework for gathering information of the behavior, analyzing the performance, and updating the behavior, the agents can adapt to changing environments or user requirements. In my thesis I use different...doctoral thesis 2021

Shekhar, A. (author), Soeiro, Thiago B. (author), Wu, Y. (author), Bauer, P. (author)DC links with back to back voltage source converters are usually built alongside the existing medium voltage ac distribution grids for infrastructure reinforcement. The distribution network operators need to run multiple of such parallel ac and dc links between two substations at optimal efficiency. This article shows that the active power...journal article 2021

Nguyen, Hoa Minh (author), Rueda, José L. (author), Lekic, A. (author), Pham, Hoan Van (author)The paper presents an approach for online centralized control in active distribution networks. It combines a proportional integral (PI) control unit with a corrective control unit (CCU), based on the principle of Model Predictive Control (MPC). The proposed controller is designed to accommodate the increasing penetration of distributed...journal article 2021

Scarabaggio, Paolo (author), Grammatico, S. (author), Carli, Raffaele (author), Dotoli, Mariagrazia (author)In this paper, we consider a smart grid where users behave selfishly, aiming at minimizing cost in the presence of uncertain wind power availability. We adopt a demand side management (DSM) model, where active users (so-called prosumers) have both private generation and local storage availability. These prosumers participate to the DSM...journal article 2021

Warmerdam, Dirk (author)In a bid to battle global warming the Dutch government has set ambitious targets to cut CO2 emissions in the Dutch Climate Agreement [1]. Aside from this state-driven initiative in line with the Paris agreement, several Dutch cities have presented their own climate initiatives. The city of Amsterdam has pledged to reduce its CO2 emissions by 55%...master thesis 2020
