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

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

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

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