Data Center Consumption

2000 70 Twh in the world 2007 330 Twh, 2% World C02 production 2011 France is the 6th electricity consumer in the world 2020 104 billion kW in European area 2008 56 billion kW in European area

How to supply Data Center ? Economically ? Environmentally ?

Challenge & Problematic

◆ Use several energy sources ◆ Green energy (solar panels, batteries, etc.) ◆ Brown energy (suppliers, etc.)

The problematic is how to characterize the heterogeneous electricity sources to make a decision to reduce electricity bills ?

◆ Control ◆ Energy Sources ◆ Energy Destinations

Introduction RenewSim Modeling Results Conclusion Introduction

Control module

◆ Find the best trade-off (electricity vs IT) ◆ Manage the power flow into the smart grid ◆ Task allocation characterize by ◆ CPU & Memory capacities ◆ Energy demand and available servers

RenewSim aims at reducing the energy cost by studying the power flow and the Data Center demand in a decision block.

Freedom degrees 1/2

◆ No degrees ◆ The power asked by the Data Center does not let us a lot freedom degrees ◆ Input of the system asked by the user and application ◆ Solar production does not depend on the system ◆ weather and time of the day ◆ Freedom degrees ◆ The Suppliers ◆ The Batteries

Freedom degrees 2/2

◆ Batteries ◆ Store energy from solar panels or suppliers ◆ Unload energy from batteries ◆ The suppliers ◆ Price depends of time (night and day) ◆ Store energy into the batteries or sell it

Element characterization

Source (St) Backup (Bt) Destination (Dt) Overflow (Ot) Gives energy to destinations Receives energy from the sources Stores energy which can not be accepted by the destinations Unloads energy which can be feed the destinations
