Cyber-Physical Energy Systems Approach for Engineering Power System State Estimation in Smart Grids

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1378219

This investigation proposes a CPES architecture and model for engineering energy management application for smart grids. In particular, the investigation considers the implementation of the power systems state estimator (PSSE). The CPES architecture has three layers: physical, monitoring and applica...

Differential feed control applied to corner matching in automated sewing

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1358918

This paper presents a new method for independent feed control in an automated sewing cell. This is important to match the corners of the parts as well as to compensate for uncertain material characteristics and variations in the length of the parts. In this method, the feed speed for the two parts i...

Work flow, material handling and initial part positioning in a multi-robot sewing cell

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1317898

This paper presents an approach for a complete sewing process, including the material handling and preparation before the sewing operation as well as material handling after the finished sewing. The complete process is divided into different tasks. The tasks include localization and stacking of the ...

Model-Based Feed-Forward and Setpoint Generation in a Multi-Robot Sewing Cell

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1251038

This paper describes an automated sewing system that focuses on sewing of curved edge segments. The sewing cell includes an industrial sewing machine as well as three industrial robots that handle the parts during the sewing process. Based on experiences from previous work, several improvements are ...

Velocity coordination and corner matching in a multi-robot sewing cell

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1205939

Automated sewing is a complicated task in manufacturing. Due to the non-rigid work pieces and variations in the material characteristics, sensor-based control has to be used to accomplish the sewing operation. This paper presents a strategy for velocity synchronization and corner matching in an auto...

Optimal Power Flow Model with Energy Storage, an Extension towards Large Integration of Renewable Energy Sources

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1204878

The integration of renewable energy sources into modern electrical grids contributes to satisfying the continuously increasing energy demand. This can be done in a sustainable way since renewable sources are both inexhaustible and non-polluting. Different renewable energy devices, such as wind power...

Deploying third party services at smart grids end users using broadband links

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1116258

Smart grids end users, such as houses and factories, already have a broadband link for common web access. We start with the hypothesis that these links can be used to exchange data between the meter/controller, at the user, and a service, at the web, using application protocols (e.g., SPDY and HTTPS...
