Next generation network analysis applications for secure and economic integration of distributed renewable generation in distribution grids

Distribution grid operation paradigms of the past such as radial operation with a clear power flow direction from feeder head to consumer have changed dramatically with the increased presence of renewable generation. The paper outlines the components of a distribution network application package that addresses the changed situation. Architectural features are described that respond to the requirements for full applicability of the package in an online environment and at the same time being open for easy integration with corporate IT. An overview on actual smart grid projects applying the package is provided.
