Reliability-Oriented Routing Metric for OSPF Protocol Applications in Transmission System Operator Use Cases

Abstract:
Curative congestion measures have increasingly captured in the interest of transmission system operators due to their numerous advantages. The potential of these measures has been subject of examination in projects such as InnoSys 2030. Successful implementation of curative congestion measures necessitates, among other things, the establishment of a per-manent data exchange infrastructure. The communication network necessary for this can be designed based on either static or dynamic routes between data sources and sinks. In contrast to static routes, which are established through manual configuration within the communication network, dynamic routes are configured automatically via routing protocols, such as the “Open Shortest Path First” protocol. In order to select a route, evaluative parameters, which are costs, must be considered. For example, the “Open Shortest Path First” protocol uses costs to evaluate connections between routers. The route between the data source and sink with the criterion of the lowest total cost is selected for data transmission. In order to achieve this, the individual links between the routers are subjected to analysis, with the costs determined in accordance with the data transmission rates. From the perspective of a transmission system operator, the most reliable route is of higher relevance than the one with the highest data transmission rate. In order to ascertain this, costs are calculated for each individual route forming the basis for this calculation. By employing this method, the most reliable route can be determined with the support of a common routing protocol.
