Market Dialogue about Gas Quality Tracking Software
Due to the increasing fluctuations in the quality of natural gas in the Danish gas grid, there is a challenge determining the calorific value in the Danish distribution gas grid. This requires intelligent and innovative software solutions that can track, calculate and simulate the gas quality in the grid. The objective of this RFI is to identify the market offerings of software, that can calculate the calorific values and the gas components based on different input and output data from consumers, flowmeters, metering stations, mix of different type of gases, etc. in different parts of the grid. By implementing an intelligent software GasNet and Dansk Gas distribution wants to avoid investing in expensive and complex metering technologies.
The requested software should be able to calculate calorific values and determine the gas components in parts of the grid including a relatively small number of consumers, small districts, often below 100. In combination with this, it should be able to simulate data pr. hour for non-hourly consumers based on a standard consuming profile in combination with ambient temperatures.
This should all be done based on the annual gas consumption for the specific consumer resulting in hourly consuming time series for each of these, which makes it possible to include the non-hourly read consumers in hourly data simulations.
The software should be able to combine this simulation with daily automatic simulations based on invalid (not validated) gas data and must be a possibility to run monthly simulations manually based on valid gas data, and when needed also correction runs.
In addition, it should be possible to run a field test, comparing simulated values with metered data. These metered data are today retrieved by the programs named Panda and Energykey and delivered by gas chromatographs placed strategically in the grid. If needed in the future, the software must meet the requirements for acquiring a PTB approval or similar
A necessity is the software’s ability to troubleshoot the different projectdatamodels in an easy and manageable way combined with the capability of creating easy-to-read charts, causing an easy access and easy possibility for validating the stability of the model.
Another tool included in the software must be the possibility of visualizing the flow of biomethane and natural gas with different calorific values in the different parts of the gas grid. The purpose is to use the visualizing for market development in form of showing the increase and flow of injected biomethane, but also to assess the results of the simulation in a simple way.
The simulation software is going to be an integrated part of GasNet and Dansk Gasdistribution billing software and should therefore be able to receive hourly input data and deliver the calculated calorific values and gas components to the billing software in both monthly, daily and hourly values.
To make the setup of the topology of the gas grid easier, the requested software must be able to integrate different GIS-data to ArcGIS and GTechnology.
Support is needed and it should not last any longer than 3 working days for the provider of the software to deliver the needed support. In the billing period the need for support is further intensified. The billing period lies in the 10 first working days in each month, and in this period the response time from the support department must be maximum 24 hours. Total amount of customers exceeds 100 000.
The software should be able to convert data from already implemented projects, where the calorific values and gas components today are simulated based on input and output data. This counts 8 projects which must be simulated daily, the downtime of the simulation in these projects must not last longer than 3 days.
The software must be able to store data for future control and simulation.
The software is to be installed within app. 6 months and followed by a validation period.
In particular Gasnet and Dansk Gasdistribution would like to know to what extent
— the market provides technical and well-proved software solutions,
— the market experience with measuring and simulating biomethane mixed into natural gas,
— accuracy of simulations of calorific value is verified and secured and stored,
— the marked has a proven track record of how data are used in a secure billing process,
— the Market has a software that has visual presentation solutions included.
