Concept
Overview Deliverable
  • It has been recognized that the Smart Grid is a
    new electricity network, which highly integrates
    the advanced sensing and measurement
    technologies, information and communication
    technologies (ICTs), analytical and
    decision-making technologies, automatic control
    technologies with energy and power technologies
    and infrastructure of electricity grids

8
Goals and Objectives
Overview Deliverable
  • The general goals of Smart Grid are to ensure a
    transparent, sustainable and environmental-friendl
    y system operation that is cost and energy
    efficient, secure and safe. Objectives of
    developing the Smart Grid are quite different
    from country to country for their various demands
    and start points.
  • However, the common objectives of a Smart Grid
    are clear and listed such as Robustness, Secured
    operation, Compatibility, Economical energy
    usage, Integrated system, Optimization and Green
    energy

Conceptual model
Overview Deliverable
  • Domains and Actors in the model

Domain Actors in the Domain
Customers The end users of electricity. May also store, and manage the use of energy. Traditionally, three customer types are discussed, each with its own domain residential, commercial, and industrial.
Markets The operators and participants in electricity markets.
Service Providers The organizations providing services to electrical customers and utilities.
Operations The managers of the movement of electricity.
Bulk Generation The generators of electricity in bulk quantities. May also store energy for later distribution.
Transmission The carriers of bulk electricity over long distances. May also store and generate electricity.
Distribution The distributors of electricity to and from customers. May also store and generate electricity.

Example
Use Case Deliverable
No Title Description
1 Demand Response (DS) Mechanisms and incentives for utilities, business, industrial, and residential customers to cut energy use during times of peak demand or when power reliability is at risk. Demand response (DR) is necessary for optimizing the balance of power supply and demand.
2 Wide-Area Situational Awareness (WASA) Monitoring and display of power-system components and performance across interconnections and over large geographic areas in near real-time. The goals of situational awareness are to understand and ultimately optimize the management of power-network components, behavior, and performance, as well as to anticipate, prevent, or respond to problems before disruptions can arise.
3 Energy Storage (ES) Means of storing energy, directly or indirectly. Smaller forms of energy storage (ES) are anticipated within distribution systems as well as bulk power systems. New storage capabilitiesespecially for distributed storagewould benefit the entire grid, from generation to end use, but the resources need to be correctly integrated into transmission and distribution operations.

Use Case Deliverable
WASA 7 Load Shedding
Description This procedure describes what activities are performed by an operator when he gets the order to release a determined value of load in a period, due to the possibility of partial or complete blackout. When the emergency situation is over, the operator has to restore the power. It is possible to create and execute certain jobs in order to restore power. Load shedding is a function to protect equipment against under-frequency. This kind of action is drastic and should only be used as a last resource. But there are situations where there is no other possibility. It can avoid danger to human life in sequence of a blackout, a voltage collapse, etc.
Stakeholders(Actors)/ Domains Operator in the transport/production control center, Operator in the distribution control room, Energy Management, Network Operation
Information Exchanges The operator in the distribution control room receives an order to release a determined value of load in a period. The system must build a list of feeders (or sub- feeders) that should be open in order to get the total of load shedding necessary. The operator (or automatic system) opens the breakers necessary according to the list, starting from the lowest priority to the highest. The system must build a list of priorities for the closing of the feeders The operator (or automatic system) restores the power to the feeder as soon as that action is possible according to the list of priorities (build in the previous step), from the highest to the lowest priority.

Use Case Deliverable
MA 1 Charging management for appliances including electric vehicle at home
Description Inside the users premise, PEV , PV system, home appliance, and household equipment participate in a home network and in load management that GW governs. PEV is considered both an electric load and an electric storage. PEV communicates to the home network.
Stakeholders(Actors)/ Domains Organization (company), Device, System, Stored information in computer memory or on media, Computer program(s) and displays / Operators, Customer(Home/Building/Commercial/Industrial)
Information Exchanges GW detects PEV coming into the garage. GW authenticates and authorizes PEV. PEV sends to GW information on e.g. charge level, miles driven, driving pattern. GW, while monitoring power generation of PV and electricity consumption of home appliances/household equipment, receives the information. GW decides whether to charge PEV, inject PEVs power to home, or do nothing. For charging of PEV, GW dictates PEV to change into the charge mode. PEV detects when its fully charged. PEV informs GW and stays stand-by. For injection of PEVs power to home, GW dictates PEV to change into the discharge mode. GW monitors status of discharging and load balance at home. GW judges and dictates PEV to stop discharging. PEV stays stand-by. When PEV goes out of the garage, GW detects it.
