Negenborn, R.R. (author), De Schutter, B. (author), Hellendoorn, H. (author)We consider multi-agent, or distributed, control of transportation networks, like traffic, water, and power networks. These networks typically have a large geographical span, modular structure, and a large number of components that require control. We discuss the necessity of a multi-agent control setting in which multiple agents control parts...conference paper 2006

Xyngi, I. (author), Ishchenko, A. (author), Popov, M. (author), Van der Sluis, L. (author)This letter describes the transient stability analysis of a 10-kV distribution network with wind generators, microturbines, and CHP plants. The network being modeled in Matlab/Simulink takes into account detailed dynamic models of the generators. Fault simulations at various locations are investigated. For the studied cases, the critical...journal article 2009

Pruyt, E. (author)Enormous future investments are needed to replace old energy systems/technologies, and prepare them for future needs. Moreover, smarter technologies/systems are needed. And in this ever more complex, interconnected, and uncertain world, smarter policymaking in the energy field is certainly needed too. After all, current energy policymaking still...conference paper 2011

van Westering, W.H.P. (author), Van Der Meulen, Michiel (author), Bosma, Wieb (author)This paper applies the distribution network reconfiguration problem to existing networks. The medium voltage distribution network of the Dutch DSO Alliander is operated using a radial topology. By optimizing this topology it is possible to reduce the energy losses caused by the cable impedances. Various solutions algorithms have been compared...conference paper 2016

Abdelmotteleb, I.I.A. (author), Gómez, Tomás (author), Reneses, Javier (author)As the penetration of distributed energy resources (DERs) escalates in distribution networks, new network tariffs are needed to cope with this new situation. These tariffs should allocate network costs to users, promoting an efficient use of the distribution network. This paper proposes a methodology to evaluate and compare network tariff...journal article 2017

Ma, M. (author), Herdeiro Teixeira, A.M. (author), van den Berg, Jan (author), Palensky, P. (author)Low-voltage distribution grids experience a rising penetration of inverter-based, distributed generation. In order to not only contribute to but also solve voltage problems, these inverters are increasingly asked to participate in intelligent grid controls. Communicating inverters implement distributed voltage droop controls. The impact of...journal article 2017

Sereeter, B. (author), Vuik, Cornelis (author), Witteveen, C. (author)Two mismatch functions (power or current) and three coordinates (polar, Cartesian andcomplex form) result in six versions of the Newton–Raphson method for the solution of powerflow problems. In this paper, five new versions of the Newton power flow method developed forsingle-phase problems in our previous paper are extended to three-phase power...journal article 2017

Eid, C. (author)The European policy focus on smart grids implies their development as an indispensable part of the future power system. However, the definition of a smart grid is broad and vague, and the actual implementation of a smart grid can differ significantly depending on the stakeholders involved. Smart electricity grids can be defined as electricity...doctoral thesis 2017

Shekhar, A. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)The role of MVDC links for distribution network expansion is important. The distribution network operators (DNOs) can maximize the power transfer capacity of existing grid infrastructure during (n-1] contingencies using reconfigurable parallel ac-dc architecture. In addition this concept involves a range of efficiency, reliability and...conference paper 2018

Zhang, H. (author), Peng, Minfang (author), Palensky, P. (author)Complex network theory is introduced to solve the islanding problem in an emergency of distribution networks. In this study, the authors put forward an intentional islanding method based on community detection. In this method, a new index has been defined called electrical edge betweenness, on the strength of edge betweenness in complex networks...journal article 2018

Evans, Michael (author), Angeli, David (author), Tindemans, Simon H. (author)We consider the problem of dispatching a fleet of distributed energy reserve devices to collectively meet a sequence of power requests over time. Under the restriction that reserves cannot be replenished, we aim to maximise the survival time of an energy-constrained islanded electrical system; and we discuss realistic scenarios in which this...conference paper 2018

Luong, N.H. (author)In our modern daily life, many activities require electricity, for example, the usage of domestic appliances, manufacturing, communication, and transportation. It is therefore essential to maintain a reliable supply of electricity to ensure the operation of such activities. The electricity supply, in a large part, depends on the underlying...doctoral thesis 2018

Abdelmotteleb, I.I.A. (author)A significant transformation has been gradually taking place within the energy sector, mainly as a result of energy policies targeting environmental objectives. Consequently, the penetration of Distributed Energy Resources (DERs) has been escalating, including self-generation, demand side management, storage, and electrical vehicles. Although...doctoral thesis 2018

Linear power flow method improved with numerical analysis techniques applied to a very large networkSereeter, B. (author), van Westering, W.H.P. (author), Vuik, Cornelis (author), Witteveen, C. (author)In this paper, we propose a fast linear power flow method using a constant impedance load model to simulate both the entire Low Voltage (LV) and Medium Voltage (MV) networks in a single simulation. Accuracy and efficiency of this linear approach are validated by comparing it with the Newton power flow algorithm and a commercial network design...journal article 2019
