FIWARE for Smart Energy Platform
At the E.ON Energy Research Center in the RWTH Aachen University, we are taking some first steps towards a cloud-based, service-oriented, open-source middle-ware platform, the Smart Energy Platform (SEP), that is capable of supporting the business models of the different Smart Energy actors. The term "Smart Energy” means making electricity grids, buildings and cities "smart” through the introduction of ICT and automated control, i.e. it covers Smart Grids, Smart Cities and Smart Buildings.

The actors who will be able to carry out their business by means of offering services through the SEP and using the services offered by other actors include, for example, Utilities, TSOs, DSOs, equipment providers, electricity retailers, electricity aggregators, energy service providers, electricity market regulators, electricity prosumers, electricity end-customers, building management firms and ICT companies. Hence, the SEP is envisaged as a hub for Smart Energy business, and must be built to be powerful, robust and secure enough to support real business use cases.
There are several technical pillars upon which SEP is based:
- use of open source software, to create a dynamic development community;
- development as a cloud-based platform, to achieve scalability (in terms of geography and size) at reasonable cost;
- use of a service-oriented architecture, allows simple, extensible APIs between the various actors, which hide underlying complexity;
- use of a 3-layer platform model (integration of various data sources, middleware and API layer) to allow SEP’s services to address multiple miscellaneous data sources.

This will provide the opportunity to test new services and components at different levels, ranging from pure software testing to hardware and Power-Hardware-in the-Loop testing. The pure software testing is suitable for testing cloud-based algorithms, services and the interfaces between them. Involving real Smart Home Gateways and Control Units in the tests, known as Hardware-in-the-Loop, enables the user to analyse the integration and interaction of real hardware with the cloud. A further step, the incorporation of the Smart Home test bed, developed at the E.ON Energy Research Center, allows for testing entire Smart Home systems, reaching from heat pumps to controllers and cloud-based services.
