Velocity Templates for Dense Swarms of Flying Robots

In the near future many tasks could be performed by swarms of flying robots. To successfully implement multiple of these swarms in the same airspace they will have to be decentralised, autonomously cope with high densities and even resolve conflicting objectives of other swarms, while remaining controllable by operators through high-level...

Accelerating the energy transition through corporate venturing at Dutch distribution system operators

The main research question that this research seeks to answer is: What are the factors that are perceived to be important for the performance of venturing units at Dutch distribution network operators? Factors found in the literature that impact the performance of this venturing units can be divided into three parts: factors from an...

Scaling Distributed Virtual Environments using Socially Aware Load Partitioning and Interest Management

Massively Multiplayer Online Games are played by millions of people from around the world who play together in large virtual environments. With sometimes even a million gamers playing the same game, the load on the virtual environments they play in needs to be distributed between servers to deal with this many players. Several techniques have...

Multi-core architecture for anonymous Internet streaming

There are two key components for high throughput distributed anonymizing applications. The first key component is overhead due to message complexity of the utilized algorithms. The second key component is an nonscalable architecture to deal with this high throughput. These issues are compounded by the need for anonymization. Using a state of the...

Sybil-resistant trust mechanisms in distributed systems

In this thesis, the problem of estimating trust in distributed systems is considered. Distributed systems can be virtual or real-world systems in which multiple agents interact. One of the biggest problems in distributed systems is that they only function well if everyone contributes some resources. If agents do not participate, or try to...

The distribution system operator as flexibility manager of distributed energy resources: A spreadsheet based simulation study on the case of the Netherlands

Within the Netherlands, house owners set up projects in which all houses within a neighbourhood are collectively renovated and equipped with distributed energy resources (DERs) at the same time. These projects are called ‘neighbourhood distributed energy resource projects’ (NDPs). As some of the equipped DERs electrify much of the heating...

The Prospects of Flexibility on Congestion Mitigation against Network Reinforcement

Traditionally, the transmission network transported electricity over extended distances from local large scale electricity generation plants to distribution networks that transported electricity to end consumers (Ekanayake, 2012). In order to ensure that such a system remains operational, a Distribution System Operator (DSO) maintains, operates...

Future energy systems and the protection of the electrical grid

One of the main research topics inside this thesis will be on what the effect will be on the present protection scheme when distributed generation units are extensively implemented inside the distribution system. The application of distributed generation will have an impact on the present protection scheme. This because the distributed...

Optimalisatie van het toekennen van artikelen aan een distributiestroom in de retail industrie

National organization of Dutch supermarkets Coop, can realize big savings by allocating products of their current portfolio to the most cost optimal distribution system. In this paper a model is described that provides insight in the costs per product. Also it compares the costs per distribution system, in order give a advice for the most cost...

Important Issues and Economic Study of Ship DC Distribution System with Variable-Speed Diesel Generator

In a traditional AC distribution system, the synchronous frequencies of the generators are coupled with the system frequency, and thus the diesel engines are kept at a constant speed. In a Dynamic Positioning (DP) vessel such as a Platform Supply Vessel (PSV), the diesel engines sometimes work at the partial load condition. The efficiency of...

Automatic Discovery of Distributed Algorithms for Large-Scale Systems

In recent years, large-scale systems have become mainstream at a very high pace. Typical examples of large-scale systems are MANETs, Wireless Sensor Networks, Pervasive Computing, Swarm Robotics, etc. These systems distinguish them- selves by the large number of devices they embody, and emergent behaviors they exhibit: Behavior that is globally...

Exploring the potential of manure-based energy production in Salland

As goals are set to increase the share of renewable energy production within the province of Overijssel, the Netherlands, the project group Groen Gas Salland is founded and has taken the initiative to explore the opportunities of green gas production through a biogas infrastructure within the region of Salland. Since within the region of Salland...

The DSO and residential energy efficiency; a good match? An analysis of the potential role of a distribution system operator in the residential energy efficiency field

Residential energy efficiency is an increasingly important notion in light of the increasing energy prices and increased focus on an environmentally sustainable society. DSO’s have the potential to make a great contribution to the field based on their unique market position, but are held back by regulation and market opposition. This article...
