The flexQgrid project is intended to make a significant contribution both to the realisation of flexibility utilisation in the distribution grid and to the provision of flexibility for upstream voltage levels and addresses the points “electricity grids” and “technology-oriented system analysis” of the 7th Energy Research Programme.

In the flexQgrid project, the approaches for a quota-based network traffic light concept developed in the grid-control project are being further developed and tested. With an intraday implementation of the approach and the establishment of secondary trading of quotas, further efficiency potential can be raised with regard to the use of flexibility. Furthermore, approaches for the provision of reactive and active power and their integration into the quota-based network traffic light concept are being investigated to support the upstream voltage levels. Essential is the willingness of the plant operators (private persons and market parties) to provide flexibility. Therefore, appropriate incentives for the provision of flexibility are investigated and affected actors are involved. In addition, the compatibility of the quota model with the legal and regulatory framework is examined and adaptation options are developed.

In order to counteract a potentially inefficient demand for flexibility through the quota model, the possibility is to be created to enable market participants to shift quotas allocated on a non-discriminatory basis among themselves in a cost-optimal manner within the framework of secondary trading. The initial focus of BlockInfinity is to participate in the conception of this platform, especially the development of suitable market mechanisms.

Based on the jointly developed concept, BlockInfinity is responsible for the technical software development of the platform. In particular, this includes the translation of the business requirements into a technical specification, its software implementation, system tests and technical documentation. The platform includes all functions relevant for trading, especially order book, matching and clearing. Distributed ledger technologies should be considered, evaluated and, if suitable, applied for implementation. In this context, DLT can guarantee equal treatment of all market participants and record market results in an unmanipulable and transparent manner.

By testing the developed market platform within the field test, the practical feasibility can be verified. BlockInfinity supports the creation of the concept for the field test and ensures the connection of all involved components from the point of view of the market platform, and operates the market platform.
