Communication system for intelligent residential electrical installations

The liberalization of the energy market is opening numerous novel opportunities to the domestic consumer (e.g. quick reaction to energy price changes). Technological support is needed to ensure that changes do not remain rather theoretical. In the following, we propose a categorization of electrical devices and an ICT solution for the communication in the new intelligent electrical residential installations.

On dependable embedded services and Openwings

Service oriented programming and service oriented architectures are the bases of one of the most successful technologies of the recent past: Web services. They support the integration at enterprise level in the global Internet era. However, the enterprise level applications are only part of the spectrum, the other being the ever growing ubiquitous embedded applications. Arguably, the SOAs offer the same advantages at embedded system level. In this article we are evaluating the service oriented paradigm in the context of distributed embedded systems and instantiate the observations on Openwings as a particular service oriented architecture.

Embedded automation for energy applications and its interdependence with the info'structure

Electrical energy applications rely ever more on an information infrastructure (infostructure), consisting of heterogeneous off-the-shelf information and communication technology for hardware, software and networking. This provides flexibility for the application, but also implies vulnerabilities as the electrical energy infrastructure depends on the correct functioning of the infostructure, in spite of random (physical) and malicious faults. In order to provide a robust application behaviour for the energy application, the infostructure needs to be fault-tolerant and able to deal with a dynamic environment; middleware can provide the required graceful degradation in case of unrecovered failures, rather than resulting in a complete breakdown.

Dependable communication middleware for residential electrical installations

The liberalization of the energy market is opening numerous novel opportunities to the domestic consumer (e.g. quick reaction to energy price changes). Technological support is needed to ensure that changes do not remain at a theoretical level. Service Oriented Programming is the basis of one of the most successful technologies of the recent past: Web Services (WS). They support the integration at enterprise level in the global Internet era. However, the enterprise level applications are only part of the spectrum, the other being the ever growing ubiquitous embedded applications. Arguably, WS offer the same advantages at embedded system level. In the following, we propose a categorization of electrical devices and a dependable ICT middleware solution, based on the concept of WS, for the communication in the new intelligent electrical residential installations.
