Established processes such as the German Redispatch\u00a02.0 process adjust the dispatch of plants to avoid congestion but do not make use of available reactive power potentials to avoid voltage-related congestion. This work evaluates the suitability of existing processes for application to reactive power. Using a\u00a0realistic distribution grid, the procedural Redispatch\u00a02.0 specifications for clustering reactive power are applied. It can be shown that the determination of reliable reactive power capability is associated with more dependencies and influencing factors than with active power. This leads to the need for a\u00a0separate cluster concept and, due to the operating point dependency, for a\u00a0procedure coordinated with the grid situation.<\/jats:p>","DOI":"10.1007\/s00502-024-01294-x","type":"journal-article","created":{"date-parts":[[2024,12,13]],"date-time":"2024-12-13T10:16:17Z","timestamp":1734084977000},"page":"421-430","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Reactive power redispatch at the TSO-DSO interface: analysis of the challenges and differences for processual integration","Blindleistungsredispatch an der TSO-DSO-Schnittstelle: Analyse der Herausforderungen und Unterschiede in der prozessualen Integration"],"prefix":"10.1007","volume":"141","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-2878-9539","authenticated-orcid":false,"given":"Nadja Isabelle","family":"Belz","sequence":"first","affiliation":[]},{"given":"Steffen","family":"Schlegel","sequence":"additional","affiliation":[]},{"given":"Jannes","family":"Gr\u00fcnberg","sequence":"additional","affiliation":[]},{"given":"Dirk","family":"Westermann","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,12,13]]},"reference":[{"key":"1294_CR1","unstructured":"50 Hertz Transmission, Amprion, TenneT TSO, TransnetBW: Electricity Network Development Plan 2037\/2045, Version 2023, 2st draft. https:\/\/www.netzentwicklungsplan.de\/sites\/default\/files\/2023-03\/NEP_2037_2045_V2023_1_Entwurf_Kap7_0.pdf"},{"key":"1294_CR2","unstructured":"Technical requirements for the connection and operation of customer installations to the high voltage network (TAR high voltage), VDE-AR\u2011N 4120, VDE FNN, Nov. 2018."},{"key":"1294_CR3","unstructured":"BMWK: System Stability Roadmap: Roadmap for achieving the secure and robust operation of the future power supply system with 100\u202f% renewable energy sources, 2023. https:\/\/www.bmwk.de\/Redaktion\/DE\/Publikationen\/Energie\/20231204-roadmap-systemstabilitaet.pdf?__blob=publicationFile&v=12.
