  3. 3. SEISMYC – SASO 2010 – Budapest, HungaryThe Current Gridn  Large power stationsn  No embedded intelligence for e.g.n  Fault detectionn  Local or distributed control / device managementn  Demand <-> supply managementn  Centralized control that is performed manuallyusing expert knowledgen  Difficult to fully incorporate small scale powersupplies dynamicallyn  Unidirectional power- and information flown  Depends heavily on forecasts for e.g. next hour ornext day
  4. 4. SEISMYC – SASO 2010 – Budapest, HungaryThe Smart GridBased on the European Technology Platform on SmartGrids it is“an electricity network that can intelligently integrate the actionsof all users connected to it – generators, consumers and thosethat do both – in order to efficiently deliver sustainableeconomic and secure electricity supplies”•  It employs•  dynamic monitoring,•  intelligent control,•  secure and fast communication and•  self* -technologies•  in order to•  better facilitate the connection and operation of generators (of all sizes)•  actively incorporates users preferences, behaviors and objectives•  provide better – in time – information and supply choices•  reduce environmental impact by e.g. improving efficiency, optimizing spatialdelivery networks•  increase reliability and security of supply and general QoS•  reduce management overheadIn addition “ SmardGrids must include not only technology, market and commercialconsiderations, environmental impact, regulatory frameworks, …, but also societalrequirements and governmental edicts”.Source: SmartGrids_SDD_FINAL_APRIL2010

  8. 8. SEISMYC – SASO 2010 – Budapest, HungaryThe Grid EcosystemBased on Workflow1.  Demand-Supply Manager (DSM)detects an decrease / increase indemand and advices HomeManagement Systems (HMS) toenable / disable (non-)essentialpower use within its ‘reach’.2.  Based on specific Prosumerpreferences and available devices,the HMS advices individual devicesto power up / down or increase /decrease power output / intake.3.  This request is received through aLAN and individual actionabledevices accept / reject the requestalso providing feedback to HMS.4.  Enterprise Apps monitor powerconsumption and adapt currentenergy costs to promote the cutback on energy.5.  Grid Overlays provide hierarchicalor network like organization onwhich DMS operate at variouslevels of granularity and on whichself-organization can befacilitated.ApplicationsDemand SupplyManagerNetworkUtilitiesProviders/CustomersEnterpriseAppsHMSDevicesGridOverlays

  15. 15. SEISMYC – SASO 2010 – Budapest, HungarySelf-Awarenessn  Whatn  Wikipedia - Self-awareness is the awareness of the self as separate from the thoughtsthat are occurring at any point in time.n  In this context – Self-awareness means that each object / device is aware of its currentstatus and context of use and their interrelation with other devices and the users that areavailable within the same environment and, in some cases, beyond.n  Whyn  Self-awareness is a pre-requisite to be able to evaluate and compare states and behaviorto pre-defined standards and values in a self-conscious way.n  This includes in particular the actual and expected consumption of resourcesn  Hown  Sense and translate relevant contextual information into device specific and situation-aware concepts to be stored, processed and evaluated by theself-aware object / device.n  E.g. smart energy profilesn  A bottom-up approachn  Centralised approach is not feasible due to the complexity and the number of objectsinvolved.n  For an IE to become fully self-aware, virtually every object or concept therein has to beself-awaren  For instance, for a home management system to be fully self- (or energy) aware, alldevices it is connect to need to be self-aware
  16. 16. SEISMYC – SASO 2010 – Budapest, HungaryActionable Devicesn  Actionable means that devices can adjust their own operationalparameters either by themselves or through external stimuli oradvice and enables the efficient and autonomous managementof devices and device ensembles based on specific local orglobal objectivesn  Actionable devices reflect both end-users as well as providersand provide the actionable interfaces that are required toautonomously manipulate demand and supplyn  E.g., individual devices may deactivate themselves for a shortperiod if available energy levels drop below a certain thresholdor device ensembles may be coordinated in a way that only amaximum number of devices is active at any given timen  Similar, components that generate or distribute energy, couldbe dynamically (de-)activated or configured, respectively, toserve energy on-demandn  Nevertheless, within autonomic frameworks, each device mustbe aware of itself and its use to override outside control ifnecessary

  18. 18. SEISMYC – SASO 2010 – Budapest, HungaryA Framework for Networked Intelligencen  If self-aware devices are only able to reason about themselves then the usefulnessof such an environment would still be limited as such objects would only exit andact in isolation. That is, if they would not communicate with other objects abouttheir current context of use or about their collective use as required for achievingmore complex tasks.n  For IE’s to become fully self-aware, virtuallyevery object or concept therein has to featuresuch a smart profile in dependence of itsindividual properties.n  This emphasizes the need for a conceptuallayer thatn  links the lower oriented physical world to a,conceptually, higher oriented user layer towhich services are offered / delivered too;n  self-organizes knowledge as well as objectsbased on their properties or context of use;n  organizes the organization as well as thecommunication and interaction between smartdevices ↔ activities ↔ users in both directions;n  Executes relevant measures in support of theself-organizing process

  20. 20. SEISMYC – SASO 2010 – Budapest, HungaryConclusions and Future Workn  The energy grid of the future is one of the most important and at thesame time most difficult vision for todayn  Socio-economic aspects offer great potential for the organization andoperation for future infrastructuresn  In particular, user behavior, commercial and regulatory frameworksneed to be incorporated into the new infrastructuren  Nevertheless, the dynamic modeling of social and economic objectivesand the subsequent adaptation of the underlying environments is stillsubject to further researchFuture work will concentrate on but is not limited ton  Efficient and dynamically configurable monitoring and analyzing techniquesn  Distributed self-organization techniquesn  Self-awareness and device management mechanismsn  Predictive Environments

  23. 23. SEISMYC – SASO 2010 – Budapest, HungaryIntelligent Environmentsn  What are they: Reflect infrastructures to which sensors, actuators and other computationalcomponents are deployed and in which they interact with each other in ordern  To monitor and to understand complex behavior and interaction between devices and users.n  With the aim to actively adapt the environment based on the current context andn  To aid the interaction between users and the environmentn  What is the problem: Considering the large number of objects involved and the potentiallyinfinite number of relationships between them it becomes ever more difficult to properlycomprehend IE’s over time.n  Solution: IE’s need to become Self-Awaren  They need to be intrinsically interwoven with dynamic and flexible monitoring systems and inferencemechanisms so that they are able to constantly establish, remove or refine the properties and therelationships that exist between different stakeholders on an operational as well as a social or businesslevel.n  This will ultimately provide the knowledge base for advanced reasoning and prediction capabilities thatwould eventually allow IE’s to self-evolve depending onn  their own dynamic context,n  individual stakeholdersn  Even more compelling, the interactions and relations between them.n  As a consequence, IE’s would be more flexible with respect to their use, they would be more resilient andfailsafe and would in general be able to provide a higher degree of interaction as well as contextualunderstanding.n  Requirement: A pre-requisite for this vision is the requirement of individual devices tobecome self-aware thus providing a high degree of understanding ofn  their own operational statusn  their context of usen  their interrelation with other devices and the users that are available within the same environment and, insome cases, beyond.
