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) � 4 th 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 DAGSTUHL Seminar 2017 - Laurent George
Applications of Energy Efficiency Smart Grids Factory of the future Micro smart Grid DAGSTUHL Seminar 2017 - Laurent George
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 DAGSTUHL Seminar 2017 - Laurent George
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,…) DAGSTUHL Seminar 2017 - Laurent George
