Redispatch 3.0

The project "Redispatch 3.0" shall on the one hand improve the integration of facilities in the low voltage grid and on the other hand improve the collaboration and information exchange between the DSO and the TSO to advance the Redispatch 2.0. The goals are increasing the share of renewable energy due to a higher degree of capacity utilization, lowering the operation and investment costs of the DSOs, and the exploitation of grid-supportive capacities from decentralized facilities, especially for the provisioning of ancillary services. Additionally, the project researches (near) real-time and resilient concepts for digitalization, which is a precondition for reactive power system management.
In the context of the subproject, the department of energy management and power system operation of the University of Kassel develops optimization tools suitable for the reactive real-time grid operation. The optimization tools are used in the case that a contingency could not be preventively removed by the grid operation planning due to forecasting uncertainties. To this end, appropriate optimization algorithms will be developed for every voltage level with focus on the low and medium voltage level. The optimizations on the different voltage levels have to be efficiently coordinated across all voltage levels with as few data exchange between the voltage levels as possible.
