Extracting Supplementary Requirements for Energy Flexibility Market Place

Finding even a partially covering set of requirements for a system may be challenging some times. The modern quick prototyping and minimum viable product approaches may not favor a full scale requirement analysis and respective design work. For this study we initially created a minimum working example of an electricity flexibility market place targeting mainly household level customers. It was successful in a technical sense as many of the features were based on the generic patterns of online trading especially on the stock markets. However, after the very brief analysis and implementation phase it was apparent that do-main expertise was necessary in some of the energy related and other general details. The expert panel was created from the research project participants rep-resenting expertise on the electrical energy, related ICT solution and grid governance field. The panel was somewhat familiar with the already existing solution and was able to produce feedback and their expert views that mostly was recorded on the free formed worksheets provided for the occasion. This research is based on the analysis of those recorded worksheets and presents an extraction of the supplementary requirements for the electricity flexibility trading market place.
