Electric power grid operation being an ever challenging scientific field is faced with a high variety of optimization problems. Since the future vision of so called smart grids causes higher complexity and new requirements to these problems, sophisticated investigation in suitable optimization algorithms is essential. Here, metaheuristic optimization strategies are proven to be suitable for high dimensional...
State-of-the-art industrial automation and control systems lack of universal communication technologies in order to handle their increasing engineering complexity. In opposition to the automation and control domain, where different field bus technologies are competing, the automotive domain has identified similar problems, founded a corporate consortium and introduced a new universal bus system. This...
Today's automation systems are increasingly composed of heterogeneous distributed components. The components of such systems communicate via different protocols and need to provide a pre-specified quality of service (QoS). For modeling such distributed applications new concepts like the standard IEC 61499 are available. But IEC 61499 does not sufficiently cover the description of the communication...
Currently applied autonomous power supplies are designed for specific energy demands and therefore rather inflexible. For an increased user friendliness, allowing attaching and detaching electrical devices without new load calculations, a flexible Power Distribution System is necessary. This can be reached by applying an Energy Management System. A concept for such a system, that is scalable by distributing...
Since IEC 61499 has reached the state of an international standard and a substantial body of research results exists the question of the authors as main intention for this paper was: Do the models of IEC 61499 solve all problems when thinking of usability and interoperability in heterogeneous system environments? The main problems discussed within the paper concern to the execution model defined for...
Modern industrial automation systems are supposed to execute applications distributed across heterogeneous networks. Additionally the market has raised a demand for downtime less operation and change of automation and control for such systems. Consequently appropriate concepts for recovering and reconfiguring devices during full operation are needed. The open standard IEC 61499 provides a scalable...
A wide range of industrial processes and applications are controlled by closed loop control systems. Such processes consist of the plant that needs to be controlled and of controlling elements such as actuators, sensors, regulators or controllers. Due to decreasing hardware costs controllers are more and more integrated into sensors, actuators or other field devices. The result is increased modularity,...
