Guarino, Luca (author)In 2018, 1.1 billion people still lacked access to energy services. Most of these people are located in remote areas which are hard to reach, especially with conventional methods of grid extension. Even if the number of people without energy access is decreasing and the number of people gaining access to electricity through renewable sources is...master thesis 2019

Marín, Luis G. (author), Cruz, Nicolás (author), Sáez, Doris (author), Sumner, Mark (author), Nunez, Alfredo (author)Prediction interval modelling has been proposed in the literature to characterize uncertain phenomena and provide useful information from a decision-making point of view. In most of the reported studies, assumptions about the data distribution are made and/or the models are trained at one step ahead, which can decrease the quality of the...journal article 2019

Adibi, M. (author), van der Woude, J.W. (author)In this paper, we present a reinforcement learning control scheme for optimal frequency synchronization in a lossy inverter-based microgrid. Compared to the existing methods in the literature, we relax the restrictions on the system, i.e. being a lossless microgrid, and the transmission lines and loads to have constant impedances. The...journal article 2019

Hügel, Casper (author)The volatile production of renewable energy sources is often considered a key issue in future sustainable energy systems. Drawing on microgrid research, we argue that the potential synergy between microgrid energy management and provision of flexibility services to the wider grid could be further explored. In addition, the trade-off between cost...master thesis 2018

de la Garza Cuevas, Roberto (author)Airborne Wind Energy is a promising technology that is becoming the point of interest for many applications. One market in which the AWE systems can open a path as a renewable distributed generator is in offgrid communities or camps. Nowadays, this market is dominated by fossil fuel energy like diesel generators. Even though the diesel is cheap,...master thesis 2018

van der Blij, N.H. (author), Ramirez Elizondo, L.M. (author), Spaan, M.T.J. (author), Bauer, P. (author)Many modelling methods for the analysis of dc distribution grids only consider monopolar configurations and do not allow for mutual couplings to be taken into account. The modelling method presented in this paper aims to deal with both of these issues. A state-space approach was chosen for its flexibility and computational speed. The derived...journal article 2018
