MC Neil, Kyle (author)As renewable energy sources and DC energy storage continue to increase in modern power systems, the power electronic converters required to interface them with existing power grids are also rapidly increasing. This is resulting in increasing amounts of the total power exchanged on the grids being converted between DC and AC. Additionally, the...master thesis 2023

Xie, F. (author), Liu, L. (author), Hao, Zhiguo (author), Lekić, A. (author), Popov, M. (author)Existing line protection methods for multi-terminal direct current (MTDC) systems are constrained by the placement and values of boundary elements. To overcome this limitation, this paper proposes a non-unit DC line protection method based on the normalized backward traveling waves (BTWs) of the 1-mode voltage. Firstly, this article studies...conference paper 2023

Stojković, J. (author), Shetgaonkar, A.D. (author), Stefanov, Predrag (author), Lekić, A. (author)This paper explores the possibilities of providing fast frequency support as an emergency support service to the disturbed AC system through the MTDC grid. A two-layer hierarchical control structure of the MTDC grid is proposed to assure the minimum cost of the frequency control actions, the minimum voltage deviations, or the minimal impact...journal article 2023

van der Horst, Koen (author), Diab, I. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)The traction substations of urban electric transport grids are oversized and underutilized in terms of their capacity. While their over-sizing is an unfortunate waste, their under-utilization creates the major hurdle for the integration of renewables into these grids due to the lack of a base load. Therefore, integrating smart grid loads such...journal article 2023

van der Horst, Koen (author)Battery electric vehicles have gained a substantial market share in the last few years. The call for good charging infrastructure is urgent with the rapid shift from carbon-based cars toward battery electric vehicles. However, the present electrical distribution networks are not designed for large additional loads. Many cities have traction...master thesis 2022

Liu, S. (author), Shetgaonkar, Ajay (author), Popov, M. (author)The objective of this paper is to investigate the coordinative performance of different types of high voltage DC (HVDC) circuit breakers (CBs) in multi-terminal DC (MTDC) grids. Several different HVDC CB technologies are emerging as a solution for the protection of offshore MTDC grids. There is a need for coordinative operation between different...conference paper 2020

van der Blij, N.H. (author), Ramirez Elizondo, L.M. (author), Spaan, M.T.J. (author), Bauer, P. (author)Due to the distributed nature of future electrical power systems, decentralized control is essential for these grids. This paper shows that converters that have identical voltage thresholds switch off simultaneously even if some could have remained operational. Therefore, inadequate system and energy utilization can occur when decentralized...journal article 2020

Mackay, L.J. (author)The traditional ac power system is challenged by emerging distributed renewable energy sources and an increase in installed load capacity, e.g., electric vehicles. Most of these new resources use inherently dc as do more and more appliances. This poses the question, if they should still be connected on ac in the low voltage grid, which was...doctoral thesis 2018
