Delivery, implementation, development and maintenance of dynamic grid planning for evida

Description

Evida needs to acquire an IT-system for dynamic grid planning. Lot 1: Evida needs to acquire an IT-system for dynamic network planning. The system will replace two existing systems, STANET and SmartSIM. Overall, the system must consist of the following features as described below: Network topology/Gas Infrastructure editor The System must have a Gas Infrastructure Editor where Evida's complete Infrastructure can be visualized in the shape of pipes, valves, Compressor stations, Regulator stations etc. The Gas Infrastructure Editor must be editable directly in the GUI in order for the Customer to make changes in the Infrastructure. Steady state simulator The System must on the basis of the data input provided by the Customer be able to perform Steady state simulations of pre-defined or customized areas of the Gas Infrastructure. Dynamic calculations The System must on the basis of the data input provided by the Customer be able to perform Dynamic calculations of pre-defined or customized areas of the Gas Infrastructure in pre-defined or customized time intervals. Gas quality calculation/tracking The System must be able to calculate/simulate the Gas quality and Gas composition based on the input and output data provided by the Customer. The accuracy of the Gas quality calculation/simulation must be precise and close to the same as real measurements directly in the Infrastructure. Heat dynamics Based on external data about temperature the System must be able to calculate the heat dynamics in the Gas Infrastructure. These calculations must be based on recognized calculation methods. Online module including: Look ahead simulator The Online module must consist of a forecast simulator, which is able to predict (hours/days) future flow, pressure and Gas quality based on historical data. Heat dynamics Same as in the normal module Gas quality calculation/tracking Same as in the normal module Linepack calculation The System must be able to calculate the Gas infrastructure Linepack based on the input and output data provided by the Customer. API for SCADA DB integration (Automatic data transfer) In order to provide the Online module with updated data in almost real time, the System must be able to receive data through a standard API with the Customer SCADA system. API for integration to Evida Data Warehouse and for the Customers GIS system (Automatic data transfer) In order to provide the normal module with updated data, the System must be able to receive data through a standard API with the Customers Data Warehouse and the Customers GIS system. Implementation of the Customer Gas infrastructure in the IT-System As part of the delivery the Supplier must build the Customer Gas Infrastructure in the System based on the GIS data provided by the Customer. The Gas Infrastructure must be coherent in order for the calculations/simulations to work properly. The supplier must continuously develop, maintain, and support the system for Evida throughout the contract period The System must be continuously improved as part of the Maintenance agreement. Continuously improved could be optimization of different features, constantly better performance, protection against security issues, introduction of new shortcuts, improved online help function etc.
