Philosophie
"   Bio-­‐inspiré : Intelligence ar.ficielle inspiré de la nature, du comportement des insectes sociaux. Le cas des abeilles vivant en essaim : l’échange d'informa.on entre elles (la distance, la direc.on, la quan.té et la nature de la nourriture) fait que, globalement, elles arrivent à résoudre des problèmes difficiles, (exploita.on de sources de nourriture, construc.on de rayons,…etc.). "   Une “intelligence collec.ve” émerge de l’interac.on entre des agents rela.vement simples. "   L’ac.on collec.ve des agents trouve des solu.ons au problème sans aucun superviseur. "   Stignergy est inspiré des principes de la ‘S.gmergie’ qui se réfère au comportement d’insectes sociaux. SEMS Assembly

SEMS operations
Two phases
•  Learning
– The terminals just measure the electrical
consumption
– Duration: about one week
•  Executing
– The terminals are active and decide to switch
ON or OFF their associated appliance
– Optimizations start in this phase
SEMS Learning - Profiles
Profiles are used to represent the consumption of a device based on
measurements and observations

SEMS Scope
•  Energy Storage Management:
 
Better valuation of local power production like photovoltaic panel
 
More Energy demand reduction -> More bill reduction
CTI grant 621K CHF – Stignergy industrial partnership with Leclanché (Yverdon)
& academic partnership, MIS of HEIG-VD (Yverdon)
•  SmartGrid integration: SEMS
 
Enable two-way communication between the energy consumer and the
energy supplier central system
 
Provide prediction charge to the balance of Demand/Response

Market
The industry and services absorb more than 50% of all electricity consumed in
Switzerland. 3% only by the pharma industry*. The figures are basically the
same in all Europe.
