• Internationally applied solutions that enable the distribution grid operator to achieve a high and further increasing feed-in of power from rooftop solar into the grid.
• Voltage in low and medium voltage grid above/below acceptable values
• Lack of remote access to Roof Top Systems (RTS) for re-dispatch, power curtailment, reactive power management, grid maintenance / switch off PV power feed-in
• Coordination of short term RTS PV forecast with grid forecast
• DSO need to call RTS owners and negotiate with them to switch off their systems for a certain time
• DSO need to go to RTS sites, request access and switch off the RTS manually
• Lack of technical data about connected RTS
• Management of data of large number of RTS (size, position, accounting, electrical behaviour, grid code compliance, etc.)
• Reverse power flow
• Increased loss of power
• Transformer overload
• Adaptation of protection settings
• Others that are relevant for distribution grid operators including voltage stability, redispatch, communication and control, thermal limits, line rating, maintenance, etc
After completing this course, participants will be able to:
• identify, analyse, compile and describe situations that typically occur in low and medium voltage distribution grids with high and further increasing penetration of rooftop solar (typical situations) as well as internationally implemented solutions
This course suits those who
• work at low and medium voltage dispatch centres which are responsible for grid operation
