Morato, P. G. (author), Andriotis, C. (author), Papakonstantinou, K. G. (author), Rigo, P. (author)In the context of modern engineering, environmental, and societal concerns, there is an increasing demand for methods able to identify rational management strategies for civil engineering systems, minimizing structural failure risks while optimally planning inspection and maintenance (I&M) processes. Most available methods simplify the I...journal article 2023

Liu, S. (author), Popov, M. (author), Belda, Nadew (author), Smeets, Rene (author), Liu, Zhiyuan (author)This paper deals with the development of an accurate finite-element model of an arrester to investigate the electrothermal and mechanical stress during dc current interruption. The comprehensive analysis performed on a ZnO surge arrester is supported by experiments during high-voltage dc circuit breaker current interruption. The performed...journal article 2022

Klerk, W.J. (author), Kanning, W. (author), Kok, M. (author), Wolfert, A.R.M. (author)Climate change and deterioration require a continuous effort to reinforce flood defences and meet reliability requirements. To efficiently upgrade flood defence systems, insight in costs and benefits of measures at a system level is required throughout the process of planning and design. Due to the size of flood defence systems the number of...journal article 2021

Fu, J. (author), Nunez, Alfredo (author), De Schutter, B.H.K. (author)Preventive maintenance is applied in distribution networks to prevent failures by performing maintenance actions on components that are at risk. Distributed generators (DGs) and batteries can be used to support power to nearby loads when they are isolated due to maintenance. In this paper, a novel short-term preventive maintenance method is...journal article 2021

Ruiz Arenas, S. (author), Rusak, Z. (author), Mejía-Gutierrez, Ricardo (author), Horvath, I. (author)Cyber-physical systems (CPSs) have sophisticated control mechanisms that help achieve optimal system operations and services. These mechanisms, imply considering multiple signal inputs in parallel, to timely respond to varying working conditions. Despite the advantages that control mechanisms convey, they bring new challenges in terms of...journal article 2020

Bhandia, R. (author), de Jesus Chavez, Jose (author), Cvetkovic, M. (author), Palensky, P. (author)Reliable power supply to the consumers is the key goal for power utilities. The two key reliability indices for power utilities are SAIDI and SAIFI. These indices indicate the average duration and frequency of supply interruptions for the consumer. A low value on these indices reflects a reliable and mostly uninterrupted power supply....conference paper 2020

Roscoe, K. (author), Hanea, Anca (author), Jongejan, R.B. (author), Vrouwenvelder, A.C.W.M. (author)In levee system reliability, the length effect is the term given to the phenomenon that the longer the levee, the higher the probability that it will have a weak spot and fail. Quantitatively, it is the ratio of the segment failure probability to the cross-sectional failure probability. The literature is lacking in methods to calculate the...review 2020

Dupuits, E.J.C. (author)Historically, people in flood-prone areas world-wide have (to a certain degree) accepted the risk of being flooded because of the benefits that flood-prone areas can provide; examples of such benefits are rich agricultural lands or trade advantages. Acceptance and benefits notwithstanding, people living in flood-prone areas have tried, and will...doctoral thesis 2019

Ochôa, Pedro (author)The adoption of composites as aircraft primary structural material has created a real need for a new aircraft maintenance philosophy to enable almost real-time structural condition assessment. It is thus crucial to develop structural health monitoring (SHM) systems capable of performing damage diagnostic and remaining useful life prognostic. At...doctoral thesis 2019

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

Bhandia, R. (author), Cvetkovic, M. (author), de Jesus Chavez, Jose (author), Palensky, P. (author)Key contributor to normal power grid operations is optimal working of the various power grid equipment/apparatus. Nonoptimal operation of any of this equipment causes power quality problems which can pose great risk to the stability of the grid. Damaged or partially damaged equipment leaves characteristic signatures in the form of current and...conference paper 2019

Dupuits, E.J.C. (author), Klerk, W.J. (author), Schweckendiek, T. (author), de Bruijn, K. M. (author)In risk analysis of riverine flood defence systems, sections of flood defences are often considered separately, herewith ignoring their interdependence, e.g. due to the hydraulic response following dike breaches in the system. In previous studies it has been found that such interdependence can have a significant influence on flood risk estimates...journal article 2019

(author), Lei, Hangtian (author), Liu, Chen-Ching (author), Tindemans, Simon H. (author)Power system operation considering an increasingly complex cyber infrastructure may be one of the key factors of the next generation power systems. The effective operation of a power system in a massively deployed cyber network environment will be affected by cyber network reliability. Therefore, it is vital not only to understand the operation...conference paper 2018

Bhandia, R. (author), Cvetkovic, M. (author), Palensky, P. (author)Deviations from normal power grid operations, such as incipient faults, equipment damage, or weather related effects, have characteristic signatures in the current and voltage waveforms. Detecting and classifying such signal distortions as quick as possible can contribute to grid reliability since grid events can be responded to in time, i.e....conference paper 2018

Schenkelaars, D. (author), Duijve, R. (author)Traditional lighting is focused on the prevention of hardware failures. With the trend toward controlled and connected systems, other components will start playing an equal role in the reliability of it. Here reliability need to be replaced by availability, and other modeling approaches are to be taken into account. Software reliability can only...book chapter 2018

Kulkarni, Raunak (author)Outage scheduling for maintenance in asset management of electrical transmission and distribution system plays an important role in power system reliability. For instance, failure probability of transmission line may change from time to time due to exogenous conditions. Impact of failure or service interruption can be described by using...master thesis 2017

Shekhar, A. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)Since shipboard power systems are inherently islanded and consist of energy intensive sources and loads, it is an interesting application for dc microgrids. The object of this paper is to explore the merits of dc based shipboard power distribution as compared to conventional ac solutions. A survey of current initiatives, emerging concepts and...conference paper 2017

Dupuits, E.J.C. (author), Schweckendiek, T. (author), Kok, M. (author)Coastal flood defense systems can consist of multiple lines of defense. In case of a system with a front and a rear defense (e.g. a storm surge barrier and levees), the front defense can improve the reliability of the rear defense by reducing the load on this rear defense. This paper develops a framework in order to assess whether including...journal article 2017

Naghibi, F. (author), Fenton, G.A. (author)It is well known that redundancy generally improves system reliability. For example, a geotechnical support system comprised of a single monopile will have the same failure probability as the monopile itself. Alternatively, if the geotechnical support system is comprised of two piles, each of which can support the load with probability 1−pf,...conference paper 2015

Tsimopoulou, V. (author), Kok, M. (author), Vrijling, J.K. (author)After the flood disaster of 1953, the Netherlands adopted a rational approach to flood risk management with the use of protection standards determined by means of cost-benefit analysis. Due to scientific and political developments that have recently taken place, an update of the Dutch protection standards is being undertaken. One of the major...journal article 2015
