Use of modern synchronous condensers in Latvian electricity transmission network

The paper presents the process of introducing synchronous condensers in the Latvian and Baltic electricity transmission network, taking into account the technical and economic studies on various technical solutions and expected investment costs. Existing market monitoring has been evaluated and summarized, including the comparison of the technical parameters. The synchronisation prefeasibility studies have been performed and their impact on the implemented solutions are presented in chronological way. The necessary activities are described in order for the Latvia and Baltic States to prepare for the desynchronization of the Baltic power systems from the existing BRELL ring and synchronization with the continental Europe power system.
