Elicitation and Analysis of Requirements for a Peer-to-Peer Energy Market

By addressing the trends of digitalization, decentralization, democratization, and decarbonization, local Peer-to-Peer (P2P) markets have the potential to significantly accelerate decarbonization at the communal level. In addition to prosumers and consumers, other stakeholders are involved in P2P trading as well. To consider the individual stakeholder interests, we extended and refined an existing methodology for establishing and analyzing the requirements for a local energy market. Thus, the paper describes the extension and application of the first part of the Development approach for Decentralized Control Systems (2DECS). According to 2DECS, we followed the four artifacts of requirements elicitation: the derivation of relevant User Stories, the "Definitions of Done", creation of Story Cards, and the establishment of Acceptance Test Requirements. In addition, we rated the individual interests of the market participants based on their potential for conflict.
