5 Identified Targets of the Redesign Process Increased security of supply Sufficient domestic resources must be available to maintain a balance between demand and generation Improved operator knowledge of actual system conditions both locally and centrally Efficient system control particularly during emergencies Active usage of distributed passive generators Black starting capabilities using distributed generators Organising distributed generators into controllable Virtual Power Plants 5

8 Primary Design Criteria for the Cell Controller Pilot Project High Ambition: In case of an emergency situation reaching the point of no return the Cell disconnects itself from the HV grid and transfer to controlled island operation Moderate Ambition: After a total system collapse the Cell black-starts itself to a state of controlled island operation High Ambitions to ensure that new features can be implemented as pure software development without replacement or installation of new hardware 8

9 The Cell Controller Pilot Project Time Schedule Phase A 2004 Information gathering through 3 international workshops. Identification and selection of 60 kv Pilot Cell Area. Requirements spec and prelim design of Pilot Cell B1 to B3 Implementation of measurement and monitoring system in Pilot Cell. Detailed modeling and simulation of Pilot Cell. Detailed design and laboratory-scale testing of Cell Controller in Colorado State University Diesel Engines Lab C1 to C3 Pilot implementation and testing of Cell Controller in test area 1, 2 and 3 of Pilot Cell

21 Cell Controller Concept Expectations Each Cell can be regarded as a Virtual Generator with same or better controllability compared to a traditional power station unit of equal size Local distribution companies attain strongly increased possibilities of active distribution network on-line monitoring and control Automatic Cell transition to controlled island operation in case of imminent transmission system break-down Black-start of transmission system Robust Cell Controller Concept designed to encompass all new types of DG units and controller functionalities Increase in security of supply Any new functionality as pure software development Re-design for the future Danish electric power system 21
