2 ICT Trends A Sciety f Intelligent Devices Everything will becme Internet-cnnected - Universal IPv6 cnnectivity ( Internet f Things ) - Ubiquitus/pervasive cmputing ( Clud ) Intelligence will becme built-in - Tw frms: lcal & glbal - Smart equipment & Netwrk intelligence Internet & Web becme service platfrm - Active, nt passive: Wrld Wide Web Web f Services - Distributed infrmatin mdels (ntlgies), IS systems, architectures n tp f it, active distributin enery netwrks Surce: Newsweek, 31 May 1999 Hans Akkermans IEA DSM Wrkshp, Sphia Antiplis, 18 May Netwrked e-services as a result

3 Hgkerk NL Field Pilt: Cmmercial Balancing, with Families and Husehlds invlved This is the first live fully integrated Smart Grids field dem in the wrld! Hans Akkermans IEA DSM Wrkshp, Sphia Antiplis, 18 May

6 Hans Akkermans IEA DSM Wrkshp, Sphia Antiplis, 18 May ICT Systems fr DER/RES Clustering & Aggregratin Requirements: Scalability: Large number f DER cmpnents Spread ver a large area Centralized cntrl reaches cmplexity limits Openness: DER units can cnnect and discnnect at will All (future) DER types must be able t cnnect Multi-actr interactin: Balancing f stakes: Lcally and glbally Crdinatin exceeding wnership bundaries Decide lcally n lcal issues. Align with Liberalized Energy Markets Multi-Agent Systems (MAS) Distributed Cntrl & Intelligence Electrnic Markets

7 Hans Akkermans IEA DSM Wrkshp, Sphia Antiplis, 18 May What is an Agent? Is self-cntained sftware prgram Mdular cmpnent f distributed & netwrked IS Acts as representative f smething r smene (e.g. device r user) Is gal-riented: carries ut a task, and embdies knwledge fr this purpse Relative independence r autnmy Is able t cmmunicate with ther IS entities (agents, systems, humans) fr its tasks inf exchange, negtiatin, task delegatin Principle f lcal infrmatin and actin Agent task types: infrmatin management, transactins, distributed cntrl strategies A Sciety f Intelligent Devices

9 Pwer Energy e-services by Smart Grid e-markets (1) Link ICT and pwer netwrks Imprve match f need, price, cnsumptin dynamically E.g. Demand Respnse Use real-time knwledge f Prices, custmer preferences Resurce needs, state frecasts Time f day, h Average Value APX: price and vlume fluctuatins Hans Akkermans IEA DSM Wrkshp, Sphia Antiplis, 18 May

10 Hans Akkermans IEA DSM Wrkshp, Sphia Antiplis, 18 May Energy e-services by Smart Grid e-markets (2) Virtual Pwer Plant: DER agents negtiate via a VPP cmputatinal market n basis f need (value, utility) and price Large-scale ptimizatin achieved in fully decentralized way Based n ecnmic market equilibrium thery Implemented by distributed algrithms using lcal data/knwledge nly

11 True [tw-way] integratin f energy markets and netwrk cntrl utility utility kwh custmer custmer utility utility & kwh inf custmer p r r x - x set price gds inputs utput Micrecnmics Cntrl Thery price resurces gal state Multi-Agent Decentralized Cntrl Thery Hans Akkermans IEA DSM Wrkshp, Sphia Antiplis, 18 May

12 Hans Akkermans IEA DSM Wrkshp, Sphia Antiplis, 18 May Micrecnmic Distributed Cntrl It can be mathematically shwn that: e-markets handle scarce resurces ptimally bth lcally and glbally ( scietally ) If scarcity is absent: peratin as cllectin f lcal cntrllers The market slutin & an mniscient central cntrller have identical utcmes Lcal data + Market cmmunicatin = Central cntrl!
