The aim of the project is to develop and test a standardized, robust and interoperable method for the utilization of reactive power potentials from the DSO for reliable integration into the transmission grid management processes (weak ahead planning process - WAPP to close to real time - C2RT). On the basis of projects and implementations already carried out with regard to reactive power optimization (Q-OPF) and provision, standardized methods, including implementation guidelines, are to be developed in consultation with the DSOs and TSOs and implemented at the participating DSOs.
This Q-OPF (based on existing preliminary work) is to be compared directly with the redispatch dimensioning and integrated into the RD2.0 platform. This enables overall system optimization to be carried out. By using reactive power, optimization potential can be leveraged with regard to redispatch dimensioning, so that the use of redispatch measures can be minimized, which leads to direct cost savings. The reactive power flexibility thus determined and available to the TSO can then be offered uniformly via the redispatch platform. TUIL has two main objectives within the scope of the sub-project. The first objective relates to the design of new methods or the expansion of existing methods for determining the reactive power potential in downstream distribution grids in C2RT operation. In the general context of determining flexibility from the distribution grid, TUIL has already contributed and expanded its knowledge in this field in several projects in consortia. What is new in this project is the extension of the methods already developed to take account of uncertainties in the underlying forecast data. In particular, the focus here is on the development of robust methods for determining secure call-off potentials by the TSO.
