Validation of a robust neural real-time voltage estimator for active distribution grids on field data

Pertl, M. (author), Douglass, P.J. (author), Heussen, K. (author), Kok, J.K. (author)

The installation of measurements in distribution grids enables the development of data driven methods for the power system. However, these methods have to be validated in order to understand the limitations and capabilities for their use. This paper presents a systematic validation of a neural network approach for voltage estimation in active...

Performance assessment of black box capacity forecasting for multi-market trade application

MacDougall, P. (author), Ran, B. (author), Huitema, G.B. (author), Deconinck, G. (author)

With the growth of renewable generated electricity in the energy mix, large energy storage and flexible demand, particularly aggregated demand response is becoming a front runner as a new participant in the wholesale energy markets. One of the biggest barriers for the integration of aggregator services into market participation is knowledge of...

CoCoA: A non-iterative approach to a local search (A)DCOP Solver

van Leeuwen, C.J. (author), Pawełczak, P. (author)

We propose a novel incomplete cooperative algorithm for distributed constraint optimization problems (DCOPs) denoted as Cooperative Constraint Approximation (CoCoA). The key strategy of the algorithm is to use a semi-greedy approach in which knowledge is distributed amongst neighboring agents, and assigning a value only once instead of an...

On integrating device level schedules into market based control

Nutma, J.S. (author), Hoogsteen, G. (author), Molderink, A. (author), Wijbrandi, W.E. (author), Hurink, J.L. (author), Smit, G.J.M. (author)

To deal with challenges introduced by the adaption of distributed energy resources, Demand Side Management methodologies are being developed to ensure the availability and reliability of our electricity supply in the future. The Power-Matcher and TRIANA are two examples of such management methodologies. As the strengths of the approaches...

Improving video event retrieval by user feedback

de Boer, M. (author), Pingen, G. (author), Knook, D. (author), Schutte, K. (author), Kraaij, W. (author)

In content based video retrieval videos are often indexed with semantic labels (concepts) using pre-trained classifiers. These pre-trained classifiers (concept detectors), are not perfect, and thus the labels are noisy. Additionally, the amount of pre-trained classifiers is limited. Often automatic methods cannot represent the query adequately...

Transactive control: A framework for operating power systems characterized by high penetration of distributed energy resources

Hu, J. (author), Yang, G. (author), Kok, J.K. (author), Xue, Y. (author), Bindner, H.W. (author)

The increasing number of distributed energy resources connected to power systems raises operational challenges for the network operator, such as introducing grid congestion and voltage deviations in the distribution network level, as well as increasing balancing needs at the whole system level. Control and coordination of a large number of...

Self Adaptive Safe Provisioning of Wireless Power Using DCOPs

van Leeuwen, C.J. (author), Yildirim, K.S. (author), Pawelczak, P. (author)

Wireless Power Transfer (WPT) technologies aim at getting rid of cables used by consumer devices for energy provision. As long distance WPT is becoming mature, the health impact of WPT becomes increasingly important to consider. In this paper we look at how to maximize the wireless power transfer to remote devices, while maintaining a safe level...

A heterarchic hybrid coordination strategy for congestion management and market optimization using the DREAM framework

Kamphuis, I.G. (author), Wijbenga, J.P. (author), van der Veen, J.S. (author)

Software agent-based strategies using micro-economic theory like PowerMatcher[1] have been utilized to coordinate demand and supply matching for electricity. Virtual power plants (VPPs) using these strategies have been tested in living lab environments on a scale of up to hundreds of households. So far, the coordination configuration of a VPP is...

Model-based engineering of runtime reconfigurable networked embedded systems

van Leeuwen, C. (author), Rieter-Barrell, Y. (author), Papp, Z. (author), Pruteanu, A. (author), Vogel, T. (author)

Today’s societal challenges, such as sustainable urban living and public safety and security require monitoring and control solutions for large-scale complex and dynamical systems. The distinguishing features of these systems are serious resource constraints, demanding non-functional requirements such as robustness, timeliness, lifetime and the...

Designing reconfigurable systems: Methodology and guidelines

Papp, Z. (author), del Toro Matamoros, R. (author), van Leeuwen, C. (author), de Oliveira Filho, J. (author), Pruteanu, A. (author), Šůcha, P. (author)

One of the major challenges when designing software for complex systems relates to a lack of a specific and comprehensive set of rules and methodologies. Even more so, adaptation to field conditions is difficult to model and implement on systems composed of a larger number of devices/components, such as distributed systems or systems of systems....

Large scale track analysis for wide area motion imagery surveillance

van Leeuwen, C.J. (author), van Huis, J.R. (author), Baan, J. (author)

Wide Area Motion Imagery (WAMI) enables image based surveillance of areas that can cover multiple square kilometers. Interpreting and analyzing information from such sources, becomes increasingly time consuming as more data is added from newly developed methods for information extraction. Captured from a moving Unmanned Aerial Vehicle (UAV), the...
