Energy efficiency in factories: Benefit of renewable energy, loT and Automatic Demand Response

Laurent George Laurent.George@esiee.fr DAGSTUHL Seminar – 27-31 March 2017

Energy efficiency in factories

At European level: H2020 Call on Factory of the Futur (FoF) In Germany: Industry 4.0 In France: Alliance for Industry of the future (Fives, Schneider Electric, Dassault Systèmes, EADS, Astrium) In US: Industrial Internet Consortium (General Electric, IBM and Intel) 4th industrial revolution (Forum on sustainable economy at Davos, 20 au 23 Janvier 2016)

Energy transition : change centralized energy production models to a distributed sustainable energy model

Applications of Energy Efficiency

Smart Grids Micro smart Grid Factory of the future

Distributed Energy sources ?

Many existing solutions:

Solar Wind Co-generation Energy Harvesting (Vibration, piezo, thermic, RF, …) Battery

Problem with distributed energy sources:

Fluctuation of energy supply

A new Energy Paradigm based on Demand Response

Legacy energy providers use demand response to shape energy pics at country level to reduce energy costs How ?

Ask their clients (factories in our case) to reduce their energy consumption for a given time, pay their clients for reducing their energy consumption Clients use their local sustainable energy (wind, solar, battery,…) during demand response to maintain their activity Problems to be solved Characterize energy demand curves in factory (based on IoT) Characterize Energy Supply functions of sustainable energy sources (energy forecasts and batteries) Determine which scheduling decisions should be taken in the factory to satisfy the level of energy requested by legacy energy provider upon demand response

Is Automatic Demand Response possible ?

New protocol: OpenADR Social network approach for energy negociation (twit of equipments,…)
