Khalilnezhad, H. (author), Popov, M. (author), Bos, Jorrit A. (author), de Jong, JPW (author), van der Sluis, L. (author)Switching operations in power systems can produce significant overvoltages under specific circumstances. With the increasing application of underground cables in transmission systems, the statistical distribution of energization overvoltages is expected to change substantially due to the different electrical characteristics of cables and OHLs....conference paper 2018

Khalilnezhad, H. (author), Popov, M. (author), van der Sluis, L. (author), Bos, Jorrit A. (author), Ametani, Akihiro (author)Energization overvoltages are among the severest overvoltages stressing insulations of EHV power system components. Since these overvoltages have a statistical nature, the insulation level should be determined with the use of a statistical approach by which the distribution of overvoltages is calculated. Literature has properly studied the...journal article 2018

Khalilnezhad, H. (author), Popov, M. (author), van der Sluis, L. (author), Bos, Jorrit A. (author), de Jong, Jan P.W. (author), Ametani, Akihiro (author)Zero-missing is a phenomenon in shunt compensated cable systems in which the current through the line breaker does not cross the zero point for several cycles. This paper deals with a thorough investigation on countermeasures of the zero-missing phenomenon in transmission systems and determines the requirements, benefits, and risks of...journal article 2018

Khalilnezhad, H. (author), Chen, S. (author), Popov, M. (author), Bos, J.A. (author), de Jong, J.P.W. (author), van der Sluis, L. (author)This paper deals with the shunt compensation design of long 380kV-50Hz XLPE cables by simulating a double-circuit partially cabled connection with the transmission length of 80km in the Dutch transmission system. The proposed procedure for shunt compensation sizing is fully elaborated in this paper. Four sizing criteria are used to find the...conference paper 2016

Thomas, R. (author), Lahaye, D.J.P. (author), Vuik, C. (author), Van der Sluis, L. (author)Simulation of current interruption is currently performed with non-ideal switching devices for large power systems. Nevertheless, for small networks, non-ideal switching devices can be substituted by arc models. However, this substitution has a negative impact on the computation time. At the same time, these simulations are useful to design...conference paper 2015

(author)Transients from lightning strikes can enter underground cables at overhead line to power cable transitions. Possible overvoltages on these surges at cross-bonding connections of the cable screens are of major concern. A model is developed for modelling overvoltages from transient signal propagation through a combined cross-bonding cable and box....journal article 2014

Hoogendorp, G. (author), Popov, M. (author), Van der Sluis, L. (author)Transmission of electric energy at high voltage levels is mainly performed by overhead lines. Nowadays, an increasing amount of power grid operators are replacing overhead transmission lines by underground cables. Cable presence in power systems may have consequences for the behavior of the total system, since cables have much larger capacitance...conference paper 2013

Idema, R. (author), Papaefthymiou, G. (author), Lahaye, D.J.P. (author), Vuik, C. (author), Van der Sluis, L. (author)Current and future developments in the power system industry demand fast power flow solvers for larger power flow problems. The established methods are no longer viable for such problems, as they are not scalable in the problem size. In this paper, the use of Newton-Krylov power flow methods is proposed, and a multitude of preconditioning...report 2012

Idema, R. (author), Lahaye, D.J.P. (author), Vuik, C. (author), Van der Sluis, L. (author)The power flow problem is generally solved by the Newton-Raphson method with a sparse direct solver for the linear system of equations in each iteration. While this works fine for small power flow problems, we will show that for very large problems the direct solver is very slow and we present alternatives that scale much better in the problem...report 2010

Hoogendorp, G. (author), Popov, M. (author), Van der Sluis, L. (author)This letter deals with the hybrid modeling of transformers and the determination of interturn voltage distribution in transformers with layer-type windings. The hybrid model uses a combination of a multiconductor transmission-line model and a single transmission-line model. The good agreement between computed and measured voltage waveforms shows...journal article 2009

Papaefthymiou, G. (author), Verboomen, J. (author), Van der Sluis, L. (author)The incorporation of wind power generation to the power system leads to an increase in the variability of the system power flows. The assessment of this variability is necessary for the planning of the necessary system reinforcements. For the assessment of this variability, the uncertainty in the system inputs should be modeled, comprising of...conference paper 2007
