Preface1.This report is part of the results of the Finnish national research project "Smart Grid andEnergy Market" SGEM second funding period. The project has been funded by Tekes – theFinnish Funding Agency for Technology and Innovation and the project partners.
This document is compiled from the separate inputs from VTT, Vattenfall AB, TampereUniversity of Technology and Nokia Siemens Networks
Authors of this document have also co-operated with colleagues in SGEM WP1 and WP4.1especially discussing SGEM vision and privacy issues.
This document has been created and generated by using Enterprise Architect (v.9.2) modelingtool. Thus the use cases and material in this document can used as a basis for next stepmodeling, if using the same or compatible modeling tool.
Purpose1.1
Purpose of this document is to find requirements for Microgrid functions by starting fromPrimary Use Case and extract its definition towards different Use Cases and their requirements. Later on this use case documentation shall be refined to cover
more specific requirements·identify subsystems and their operations·more detailed contents of the use cases·more technical specifications serving the implementation·
Another purpose of the use cases is to serve as a communication tool between the partners torefine the next steps.
Primary Use Case used as reference model is based on Microgrid Model defined by the IEEE[1].
Scope1.2The scope of the system under study is to manage active electric resources at residentialcustomer sites and aggregating them to useful bundles for both technical and market operationpurposes. Turning on and off residential electric loads and energy sources remotely is called asDemand/Response (DR). It is a dynamic demand mechanism to manage customer consumptionof electricity in response to supply conditions.
Stakeholders for the scenarios and use cases are shown as actors of the model. An actor isactually a role, which can be played by several physical entities. Basically the systemboundaries can be defined exactly by specifying interfaces between the actors and the system.
The demo development is split into three phases, called sprints according to agile approaches.

Modeling Approach2.Our modeling approach is slightly modified from main stream use case modeling approachesand the ones used in ADDRESS and other EU projects.
The most important terms in the process of creating use cases are:
Vision·
Future Scenario·
User /Market Scenario·
Use Case·
Vision2.1Vision tells on general level in what kind of future environment from smart grid perspectivescenarios and use cases take place. Vision is created by WP1 and we use it as a background.The vision was studied and complemented in the UCEG workshop in June 2011.
Scenarios2.2
Future Scenario2.2.1Format for the future scenario documentation is totally free. Teams developing the use cases donot need to write their own future scenario.
User Scenario2.2.2User scenario(s) are the starting point for the use case modeling. User (usage) scenario isconcrete description of a very specific interaction, but one that is typically chosen for someparticular reason. I.e. they have clear scope and goal. E.g. it is important to discover, how ansuburban family uses EV in the morning.
Compared to use case the format of a user scenario is more creative, but also more freeformed. User scenarios are typically narrative versus the bulleted / numbered form of a usecase. They incorporate individual user characteristics (i.e. a persona) while outlining the tasksundertaken to achieve goals. Essentially, you tell a short story about your persona interactingwith a product.
User Story2.2.3User Story is one or two sentences in the everyday or business language that captures what theuser wants to achieve and benefit. User stories are used especially with agile softwaredevelopment methodologies (especially with SCRUM) for the basis of what features that canbe implemented. User story is one format of documenting a user scenario.
Each user story is a short text and should fit on a paper note/card. The user stories are writtentogether with SW customers and/or users. Focus in customer interviews is in functional

Trigger Action
...
The main goal with user stories is to reduce the excessive and complex requirementdocumentation i.e. requirement management. Instead of that selection of user stories areimplemented very quickly and used as a communication tool with users to verify and refine therequirements.
Market Scenario2.2.4The goal in market scenarios is to identify players, products and market potential in the certainscenario. Market scenarios can also be very personal and use real names, but typically peopleavoid using real company names.
Use Case2.3Use Case is a functional specification of the system under study. In the system model every usecase must be associated with external actors that either call the use case to occur or providenecessary external service in carrying out the requested functionality.
Use Case Realization2.3.1During system design phase use cases are refined in to use case realizations, which explain thefunctionality as sequence of interaction between the parts of the systems and external actors.Use case realizations are detailed and enlist the actors, a brief description, pre-conditions, themain flow (i.e. happy path) and any alternate flows, sub-flows and exception flows. It will alsodescribe the state of the system at the end of each flow, happy or otherwise (i.e.post-condition).
Use case realizations can be documented as diagrams (UML sequence diagram or activitydiagram) or as text, for example, like this:

requirements. SW developers can also write user stories, but then the focus is in non-functionalrequirements.
D 6.6.2
Association Technical A relationship between two or more entities.Implies a connection of some type - for exampleone entity uses the services of another, or oneentity is connected to another over a network link.
Category Definition
Class Technical A logical entity encapsulating data and behavior.A class is a template for an object - the class isthe design, the object the runtime instance.
End conditions
It is very important to keep use cases and also use case realizations technology agnostic asmuch as possible.
Summary2.4Figure below illustrates the use case development. Future scenario content is in fact defined byvision developed by WP1. All the user scenarios, stories and use cases share the same futurescenario.
The actual use case writing team starts with user scenarios and stories. Scenarios can bewritten together with customers and users. User stories must be written with users, customersor their representatives.
Use cases are documented based on user scenario and selection of user stories, which refine theuser scenario with more detailed (functional) user requirements.
Figure 1: Use Case Writing Process
Glossary2.5Quite many items are based on [2]
Component Model Technical The component model provides a detailed view ofthe various hardware and software componentsthat make up the proposed system. It shows bothwhere these components reside and how theyinter-relate with other components. Componentrequirements detail what responsibilities acomponent has to supply functionality or behaviorwithin the system.
Accounting Periods Business A defined period of time whereby performancereports may be extracted. (normally 4 weekperiods).

Deployment Architecture
Extends Relationship Technical A relationship between two use cases in whichone use case 'extends' the behavior of another.Typically this represents optional behavior in ause case scenario - for example a user mayoptionally request a list or report at some point ina performing a business use case.
Technical A view of the proposed hardware that will makeup the new system, together with the physicalcomponents that will execute on that hardware.Includes specifications for machine, operatingsystem, network links, backup units &etc.
Includes Relationship Technical A relationship between two use cases in whichone use case 'includes' the behavior. This isindicated where there a specific business use caseswhich are used from many other places - forexample updating a train record may be part ofmany larger business processes.
A person or a company that requests An entity totransport goods on their behalf.
Customer
Use Case Technical A Use Case represents a discrete unit ofinteraction between a user (human or machine)and the system. A Use Case is a single unit ofmeaningful work; for example creating a train,modifying a train and creating orders are all UseCases.Each Use Case has a description which describesthe functionality that will be built in the proposedsystem. A Use Case may 'include' another UseCase's functionality or 'extend' another Use Casewith its own behavior.Use Cases are typically related to 'actors'. Anactor is a human or machine entity that interactswith the system to perform meaningful work.
Deployment Model Technical A model of the system as it will be physicallydeployed

System Overview3.
Modeling of Microgrid is started from the Micro Source (MS) level. On that level basic idea isto keep MS and it's controller entity Micro Source Controller (MC) as self-autonomic aspossible. When Microgrid is connected to Utility Grid and other Microgrids there is need tohaggle from self-autonomic.
Application Scope3.1In the long run one specific scope in the research and development is of course Microgridcontrol itself and communication solutions needed to enable reasonable QoS. In applicationdomain sense the focus is on the customer site and its aspects:
Generic Microgrid Model [1, modified]·Demand Management based on criticality of load·State Resolver·MG Controller and Management System Applicability·
Interoperability3.2Microgrid application has several interfaces to other systems and a lot of internal interfaces. Itexploits heavily the functionality and information of the other applications and in turn servesother applications. Interoperability issues will be included here later.
Technical Environment3.3Technical environment is discussed in a separate deliverable.
How Microgrid is defined in this document3.3.1
In this document Microgrid is seen as a one area of Microsources and loads that are possible toisolate as one self organized island. Microgrid can operate parallel with utility grid also.Following picture can be one possible example how Microgrid is defined.

Notes: Demand Response Micro Source Controller is just one type of Microsourcecontroller. EMM and PCM do control it's functions on upper hierarchy.
Some loads like hot water boilers, floor heating or other loads which are able to maintainbig heat accumulation are loads which can be used as non-critical loads. They are likenatural energy storages for short- to middle term balancing purposes. Also chargedaccumulators are in same group until charge level is not optimal for existing MicrogridInternal Sate. When extra energy for non-critical use is available according to MicrogridController Algorithm, these big hysteresis load elements can be loaded again. In countrieswhere fireplaces are commonly used, it is natural to take this, often very long term energystorage, in to criticality calculation. It can be done for example with thermo coupleconnection or any other thermal feedback information. One important topic concerning toSmart Home Automation is of course the indication if human is presence when home loadcriticalities are calculated.
Short circuit motors can be a problem from MG startup view. It is highly dependent onsituation, motor starting appliances and motor size how to classify SC-motor criticalityalso used starting support equipments are effecting how grid do see motor. In case ofrelative big motors connected as DOL (Direct-On-Line) motors can be problem. Thisrelativity comes from motors nominal powers / starting current compared to grids nominalshort-circuit power. If DOL motor need to accelerate from zero rotation speed to nominalspeed or load speed, there is some topics need to take in account from criticality viewpoint.Motor can take 5 to 7 times its nominal currency in start phase which can cause collapsingof weak grid. DOL motor can be kept connected if it already rotates near its nominal speedand short-circuit power of the underlying grid is enough big. All previous phenomena’s doeffect how underlying grid do see the load criticality. When underlying network collapses,rotating motor is seen as generator (this means that energy stored in motor’s inertia ispushed back to grid) from grid viewpoint this gives requirements to safety automation. Invery minor viewpoint rotating inertia is seen as short term energy storage.
Sometimes MG can be used to maintain utility grid stability. Then main grid operator canoperate one of the following ways. Operator can request to off-switch non critical load butkeep rotating energy sources connected and even command extra generators (diesel) tosupport main grid stability. One possible scenario is that operator MG is commanded toisland mode then utility grid is supported by degreased load. In both case Overlay GridOperator should give compensation to MG Operator and there is needed Control Logic torespond Utility Grid Operator’s demands.
