  3. GAS TRANSPORT SYSTEM – TECHNOLOGICAL VIEW 9th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia

  4. 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 • Allocation 9th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia

  5. 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 • Pure dynamic simulation 9th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia

  6. 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. 9th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia

  8. 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. 9th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia

  9. Nomination validation procedure SIMONE Nomination workplace Legend: PRSIM - realtime simulation scenario ZYSIM - «Look-Ahead» simulation scenario NOSIM - nomination validation scenario (for the next gas day) RESIM - renomination validation scenario (for the rest of actual gas day) ICU - complete state of gas transport system model 9th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia

  13. 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) • SIMONE expanded with web service requestor (consumer) 9th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia
