Due to the increasing penetration of distributed energy resources and EV charging points, the distribution grids will be operated closer to their technical limits in the future. As a consequence, grid operators have to establish increased transparency about the current grid state (particularly on low voltage level) to ensure the reliability of power supply. The IGP applications in the field of grid operation provide detailed information on the current and the future grid state to the system managers. For this purpose, interfaces to the control system and to measurement devices in the grid are established. The current grid state is derived by using state estimation algorithms. Furthermore, the IGP Operation applications provide recommendations for the congestion management in case of imminent grid bottlenecks.
Provide information on the current grid state in real time by using state estimation algorithms based on live measurement data from the control system
Provide intraday and day-ahead forecasts of the grid state (line utilization and voltage levels) based on load and generation forecasts
Provide real time recommendations to resolve bottlenecks in the grid taking into account grid related measures as well as load and generation flexibilities
Simulate the effects of switching operations in order to identify potentially meshed, blacked-out or overloaded assets and grid areas
