Haleem Medattil Ibrahim, M.I. (author), Sharma, Madhu (author), Subramaniam Rajkumar, Vetrivel (author)Monitoring, protection, and control processes are becoming more complex as distributed energy resources (DERs) penetrate distribution networks (DNs). This is due to the inherent nature of power DNs and the bi-directional flow of current from various sources to the loads. To improve the system’s situational awareness, the grid dynamics of the...journal article 2023

Markensteijn, A.S. (author)Energy systems are vital in modern society, and reliable operation is crucial. Multi-carrier energy systems (MESs), which couple two or more single-carrier systems, have recently become more important, as the need for sustainable energy systems increases. Important tools for the design and operation of energy systems are steady-state simulation...doctoral thesis 2021

van Westering, W.H.P. (author)The volatility of renewable energy sources pose a significant challenge for Distribution Network Operators (DNOs) as it makes planning and maintaining a reliable electricity grid more complex. An essential tool in dealing with the uncertain behavior of renewable energy resources is the load flow simulation, i.e., the standard electricity network...doctoral thesis 2021

Verhoeven, Gijs (author), Vergara Barrios, P.P. (author), Kok, Koen (author)Currently, the majority of the available test feeder models are based on the North American type of distribution systems, leaving an absence of representative feeder models for the European (and Dutch) types of distribution systems. Therefore, a standardized set of power flow models for typical Dutch LV distribution networks is developed using...conference paper 2021

Kootte, M.E. (author), Vuik, Cornelis (author)This paper compares and assesses several numerical methods that solve the steady-state power flow problem on integrated transmission-distribution networks. The integrated network model consists of a balanced transmission and an unbalanced distribution network. It is important to analyze these integrated electrical power systems due to the...journal article 2021

Markensteijn, A.S. (author), Romate, J.E. (author), Vuik, Cornelis (author)Coupling single-carrier networks into multi-carrier energy systems (MESs) has recently become more important. Conventional load flow models for the separate single-carrier networks are not able to capture the full extend of the coupling. Recently, different models for multi-carrier energy networks have been proposed, either using the energy...journal article 2020

Jonker, Stan (author)This thesis covers the power load flow problem and three numerical methods which can be used as a solution. We firstly discuss the concepts from electrical engineering required to discribe the problem. This includes alternating current and voltage and admittances of various electrical elements. We then use these concepts to derive a set of...bachelor thesis 2020

Markensteijn, A.S. (author), Vuik, Cornelis (author)Coupling single-carrier networks into multi-carrier energy systems (MESs) has recently become more important. Various formulations of the single-carrier load flow problem (LFP) are used. Moreover, different coupling models lead to different integrated systems of equations for the LFP of MESs. Both could affect the convergence of the Newton...conference paper 2020

Khuntia, S.R. (author), Rueda, José L. (author), van der Meijden, M.A.M.M. (author)Location of wind power plants and demand centres are not always close by; hence, the transmission of energy puts a burden on existing grid infrastructure. This unwanted burden necessitates transmission lines to operate more and more frequently close to their operating limits. To alleviate such situations, this research addresses the advantages...journal article 2019

Markensteijn, A.S. (author), Vuik, Cornelis (author)The coupling of single-carrier network into multicarrier energy systems (MES) has recently become more important. Conventional single-carrier steady-state load flow models are not able to capture the full extent of the coupling. Different models for multi-carrier networks have been proposed, either based on the energy hub concept or using a...conference paper 2019

Rinaldo, Stefano Guido (author), Ceresoli, Andrea (author), Lahaye, D.J.P. (author), Merlo, Marco (author), Cvetkovic, M. (author), Vitiello, Silvia (author), Fulli, Gianluca (author)The upward trends in renewable energy penetration, cross-border flow volatility and electricity actors’ proliferation pose new challenges in the power system management. Electricity and market operators need to increase collaboration, also in terms of more frequent and detailed system analyses, so as to ensure adequate levels of quality and...journal article 2018

Çetinay Iyicil, H. (author), Kuipers, F.A. (author), Van Mieghem, P.F.A. (author)This paper combines the fundamentals of an electrical grid, such as flow allocation according to Kirchhoff’s laws and the effect of transmission line reactances with spectral graph theory, and expresses the linearized power flow behaviour in slack-bus independent weighted graph matrices to assess the relation between the topological structure...journal article 2018

Larrañaga Arregui, Amaia (author)European countries are showing their willingness to reduce their greenhouse gases emissions in the coming years. For example, the Paris agreement within the United Nations Framework Convention on Climate Change (UNFCCC) is one of the most crucial steps that countries have signed recently. The aim is to cause a lower global temperature increase,...master thesis 2017

Leal, A. (author)Chile is an energy independent country; goal achieved due to the diversification of the energy matrix and promoting exploitation of renewable energies. On the other side, Argentina holds permanent electricity importations from its neighboring countries, relying on these transactions to supply its demand.

(author)Analytical expressions are derived to gain insight in the operating principles of phase shifting transformers (PSTs) in a highly meshed grid. To this extent, the dc load flow algorithm is adapted to account for such devices. This leads to a linear expression for the relation between PST settings and the active power flow in the lines. Based on...journal article 2008
