Programming Languages & the Power Grid • Sebastian Egner • GOTO 2013

From the creator

This presentation was recorded at GOTO Aarhus 2013 http://gotocon.com Sebastian Egner - Head of Application Development at Entelios AG ABSTRACT The topic of this presentation is software connected to the electric power grid. It is the story of an application area in need of modern programming languages, rather than the other way around. The young company Entelios AG in Berlin, has developed a complex piece of software to help stabilize the grid by reducing demand at times of short supply. The software has been designed based on the principle of 'choosing the right language for the job', and the reasoning behind some critical design choices will be explained. But while the reasoning at the time of design determines our choices, it is the confrontation with the practical outcomes of these choices that guides our learning and how improvements and future systems should be implemented. This design and engineering approach will be a major theme of the presentation. The second major theme of the presentation is the type of software employed in the power grid in general. Obviously, the power grid does already represent a well developed software ecosystem ranging from (hard) real-time systems to business IT solutions. Since a national power grid is a system with engineering of highest complexity it would be presumptuous to attempt any kind of exhaustive overview. Yet, it turns out that 'internet technology', which is currently confined to the GUI side of the business IT solutions
