1 Integration of Simone Capacity Tools and Gas Transport Commercial Management System Zdravko Oklopčić (Končar-KET, Croatia), Martin Stýblo (SIMONE Research Group, Czech Republic) 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia

2 GAS TRANSPORT SYSTEM – COMMERCIAL VIEW

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

4 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia GAS TRANSPORT SYSTEM COMMERCIAL MODEL Commercial entities: Commercial entities: ::: Entry and exit points Market players (shippers, DSOs, SSOs, regulatory agencies, etc.) Structure Physical entities: Physical entities: Off-take and in-take stations Metering lines Physical receiving and delivery points Structure Relations between commercial and physical entities : 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 Basis for commercial application modules Commercial contracts Nomination Metering Allocation

5 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia SPECIAL TASKS OF COMMERCIAL GAS MGMT Free capacity calculation: 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: 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: 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

6 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.

7 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia CAPACITY CALCULATION - block diagram Scenario generator Selection of gas network model Commercial entry / exit flow data Boundary in / out flow scenario Repository of gas network models Simone boundary flow scenario Simone execution scenario Simulation execution Continue ?

8 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia Capacity calculation procedure Procedure steps 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 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 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia 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

10 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia System architecture IBM WebSphere middleware (ESB, Message brocker, XML) Commercial gas transport mgmt DB ORACLE TeleReading DB ORACLE ERP DB ORACLE ERP (Oracle E- Business Suite 11i) IBM WebSphere (Company portal) Internal users External users Adapter TeleReading (GEMA Gas) Adapter Commercial Gas Transport Management System Adapter SIMONE Capacity Tool Adapter SIMONE Online ABB NM UDW ABB NM SCADA Adapter SIMONE user UDW ORACLE AVANTI ABB

12 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia CAPACITY CALCULATION DATA FLOW Commercial system DB Input data for scenario gen. Generated scenarios Scenario generator Web service provider SIMONE Client Web service requestor (consumer) Selection parameters Commercial user Simulation execution control SIMONE user XML documents

13 9 th SIMONE Congress, October 15-17, 2008 Dubrovnik, Croatia Conclusion SIMONE is used to meter gas transport system capacity 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 Standard SIMONE application is expanded to enable iterrative calculation of gas transport system capacity and validation of nominations 2 SIMONE applications used: 2 SIMONE applications used: SIMONE Capacity Tool SIMONE online In order be able to execute simulation SIMONE needs large amount of input information : 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 Simulation results have to be returned to external application Requirements for communication between applications: 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) SIMONE expanded with web service requestor (consumer)
