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

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

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:



In order be able to execute simulation SIMONE needs large amount of input
information :




SIMONE Capacity Tool
SIMONE online
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
–
–

Implementation of application integration infrastructure
–
–
–
–
–

Data transformation in the form which can be utilized in destination application
Data structure stored in the Commercial Gas Transport Management System DB
SOA priciples
