  1. 2nd Workshop on Energy for Sustainable Science at Research Infrastructures Report on Parallel Session A4: Energy Quality and Operation __________ Roberto Visintini

  2. Energy Quality and Operation – 1 High Temperature cooling of cryoplant and klystrons (J. Jums – ESS) • “4R-based” energy concept at ESS • 40 MW of electrical power, most of it turned into waste heat  recycle heat! • Lund District Heat System = source and customer • 71% of all & 100% of high grade heat: RF & Cryoplants • Focus on RF & Cryoplants • Balance the risk of klystron collector high temperature (80-90 C) cooling with benefits from heat recovery • There are risky choices but many benefits are possible Report on Parallel session A4

  3. Energy Quality and Operation – 2 Three years of operation of the Elettra tri-generation plant (R. Visintini – Elettra) • At the Elettra Center the second tri-generation plant has started operation. • About 6400 hours/year of operation • Mains disturbances affect 1-2% of downtime (max allowed 5%) • Elettra Storage Ring benefits from the increased power from UPS fully protecting its superconducting cavity • More power is now available from TGP2 • Feasibility study for protecting additional critical plants, in the Storage Ring, in particular the 4 RF plants Report on Parallel session A4

  4. Energy Quality and Operation – 3 Design and simulation of a SMES for grid primary control (H-J. Eckoldt – DESY) • Make use the many assets of DESY for a study on an innovative SMES (Superconductive Magnet Energy Storage) • Large power & energy storage (+/- 40 MW – 25 MWh) • Superconductive coil design derived from the one of ITER • Notwithstanding its size, the energy capacity is relatively low • Best application: regulation of grid frequency • Simulation results confirm SMES feasibility as Primary Control Power • Cost analysis: 14 years for amortization Report on Parallel session A4

  5. Energy Quality and Operation – 4 Advanced Simulation tools in support of the design of the Power System architecture of the European Spallation Source (ESS) (J. Tang– RWTH Aachen) • 2-year project on ESS and Lund regional grids simulation • Models for the regional Lund and internal ESS grids to evaluate mutual impact • Use of Real-Time co-simulation software and hardware, complementary simulation tools (RTDS, Opal RT, MATLAB/Simulink) • Various scenarios have been tested, in normal and fault conditions • The simulation of two LINAC charging schemes show large impact on the quality of the Lund grid. Report on Parallel session A4
