GAS TRANSPORT SYSTEM COMMERCIAL MODEL

• Commercial entities
• Entry and exit points
• Market players (shippers, DSOs, SSOs, regulatory
  agencies, etc.)
• Structure
• Physical entities
• Off-take and in-take stations
• Metering lines
• Physical receiving and delivery points
• Structure
• Relations between commercial and physical
  entities
• Physical receiving points by commercial entry
  points
• Physical delivery points by commercial exit
  points
• Basis for commercial application modules
• Commercial contracts
• Nomination
• Metering

SPECIAL TASKS OF COMMERCIAL GAS MGMT

• Free capacity calculation
• Executed periodicaly (eg. quarterly or monthly)
  or on demand
• Starts with current year and goes several years
  into the future
• Calculations are performed for several typical
  yearly load patterns
• Future gas network expansions have to be taken
  into account
• Static or periodic day dynamic simulation
• Capacity booking request validation
• Executed on demand in connection with booking
  request
• It is performed for time period of the booking
  request
• Calculations are performed for several typical
  yearly load patterns
• Future gas network expansions have to be taken
  into account
• Static or periodic day dynamic simulation
• Nomination / renomination validation
• Executed daily for nomination validation or on
  demand for renomination validation
• Calculation is performed for next gas day
  (nomination) or actual gas day (renomination)
• Nominated and/or typical daily load curves
• Actual gas network (LIVE), with initial state
  imported from look-ahead simulation

SCENARIO GENERATOR

• Scenario generator functions
• Selection of network model,
• Creation of basic boundary flow scenario,
  structured according to physical off-take and
  in-take nodes using data on capacity booking and
  nominations, structured according to commercial
  entry / exit points,
• Definition of control parameters for prorating
  algorithm,
• Selection of control variant,
• Inserting created scenarion in scenario table in
  DB
• Transformation of calculated boundary flow
  profiles, structured according to physical
  off-take and in-take nodes, into load profiles,
  structured according to commercial entry / exit
  points.

Capacity calculation procedure

• Procedure steps
• Invoking Scenario Generator
• Reading input data from commercial DB
• Scenario batch generation
• Insertion of generated scenarios in commercial DB
  
• Request to SIMONE user to perform simulation
• Reading generated scenario batch, performing
  calculation and returning calculation results in
  commercial DB
• Scenario Generator transforms calculation results
  into commercial capacities and updates
  appropriate tables in commercial DB
• Data exchange between two systems
• Access to commercial DB enables appropriate web
  service provider
• On Simone side there is web service requestor
  which enables Simone system to consume services
  enabled by web service provider
• Communication between web services is performed
  by XML documents
• Using this mechanism Simone user is able to
• Navigate through the list of generated scenarios
• Request transfer of selected scenario batch in
  Simone program
• Request transfer of calculation results in
  commercial DB.

Conclusion

• SIMONE is used to meter gas transport system
  capacity
• Standard SIMONE application is expanded to enable
  iterrative calculation of gas transport system
  capacity and validation of nominations
• 2 SIMONE applications used
• SIMONE Capacity Tool
• SIMONE online
• In order be able to execute simulation SIMONE
  needs large amount of input information
• Gas network models (maintained in SIMONE)
• Scenarios (based on externally generated data)
• Simulation results have to be returned to
  external application
• Requirements for communication between
  applications
• Commercial gas transport system model
• Data transformation in the form which can be
  utilized in destination application
• Data structure stored in the Commercial Gas
  Transport Management System DB
• Implementation of application integration
  infrastructure
• SOA priciples
• Web services
• XML documents
• Portal
• IBM WebSphere (ESB, adapters, message brocker)
