Reconfigurable manufacturing systems (RMS) with a rearrangeable structure can quickly adjust their productivity to meet the dynamic market changes and the demand for high-variety products. Industry 4.0 technologies have enhanced the RMS flexibility and made the automation of the reconfiguration of the manufacturing system possible. As an Industry 4.0 technology, wireless power transfer (WPT) can ...

ABSTRACT The growth of the world’s population leads to increased energy needs. The use of fossil energy leads to challenges. The main reason for this is that the use of fossil fuels has a negative impact on global climate change, and the world is heading towards running out of fossil fuels in a few years. Renewable energy sources like photovoltaic and wind power plants are good solutions for those ...

The thesis examines which energy production methods are suitable together with seasonal storage of energy at UiT the arctic university of Norway in Narvik. Nordkraft has provided the subject which has been examined. The location of UiT Narvik together with its areas and storage volumes have been examined for what power production methods and energy storage methods are suitable for this location. ...

Inverter-based resources (IBRs), such as solar and wind power are gaining popularity because of their increasing acceptance, environmental benefits and decreasing costs. However, their integration into power systems can lead to significant impacts on system inertia and frequency stability, which are crucial for maintaining the reliability of the power grid. In traditional power systems, the synchronous ...

In this paper, we address modelling and simulation of dynamics involved in docking of large marine vessels with aid of tugboats, with the aim of providing a tool for improved design of control algorithms for autonomous docking operations. Mathematical models of the docking vessel and tugboats in 3DOF are derived, with a special focus on realistic interactions through towline, contact and friction ...

The increasing integration of distributed energy resources such as photovoltaic (PV) systems into distribution networks introduces intermittent and variable power, leading to high voltage fluctuations. High PV integration can also result in increased terminal voltage of the network during periods of high PV generation and low load consumption. These problems can be solved by optimal utilization ...

Studien fokuserer på det teoretiske rammeverket som er nødvendig for å forstå problemet. De teoretiske delene inkluderer grunnleggende elektriske sannheter og deres effekter på hovedkomponentene i et kraftsystem. Den gjenværende teorien ...

Electricity load modeling plays a critical role to conduct load forecasting or other applications such as non-intrusive load monitoring. For such a reason, this paper investigates a comparison study of two common artificial neural network methods (Multilayer perceptron (MLP) and radial basis function neural network (RBF-NN) for home load modeling application. The accuracy of load modeling using ...

A system of several wireless sensor nodes and one unmanned aerial vehicle (UAV) is considered in this research. The nodes are only floating and drifting with the sea stream. The UAV will be operating as a data mule to gather sensing information from wireless sensor nodes. Unlike prior studies, this paper addressed a realistic ocean model for the nodes movements which will be the references to the ...
