In the coming years, analyses in low-voltage grids will play an increasingly important role due to the decentralisation of generation and changing user profiles. At the same time, the Consumer & Market Authority is making new, higher demands on grid safety. Distribution system operators can't possibly analyze and assess all MV and LV grids manually (and in conjunction).
For this purpose Phase to Phase has developed the web application Vision Cloud Solution. Vision Cloud Solution automatically calculates, analyzes and assesses MV and LV grids. Asset managers, network designers, relationship managers and fault mechanics, but also other professionals gain insight on a large and small scale into the present and future behaviour of their grids.
Vision Cloud Solution can be used for grid planning, grid design and sustainable area development. Thanks to its clear, unambiguous presentation, Vision Cloud Solution also promotes communication and thus collaboration between authorities and the public.
Easy insight into current grid structure, grid capacity and grid and contact safety per component and aggregated per LV grid.
Self-adjustable colour classification.
Always up-to-date grid models available.
Rapid calculation of scenarios for increase of the number of solar panels (PV), heat pumps (HP) and charging stations (EV) in the grids.
At building, district, city or provincial level.
Click on components and view results.
Actual net files (gnf, vnf) combined with up-to-date BAG (Land Registry and Mapping Agency) and CBS (Statistics Netherlands) data.
View power supply areas, with colours indicating which house connections are connected to which main cable or medium-voltage substation.
Suitable for standard maps and photo backgrounds. Link to Cyclomedia panorama photos possible.
Now, Vision Cloud Solution offers the ability to automatically calculate, analyze and assess actual MV and LV grids in bulk. This applies to both 'As-is' situations and 'What-if' analyses. Vision Cloud Solution can be used by:
Vision Cloud Solution consists of Vision Web, a web application with 3D geographical presentation via WebGL, and Vision Engine, a universally applicable calculation core accessible via an API.
Vision Web uses standard Vision and Gaia network files for presentation, calculations and analyses.
Database with up-to-date data from network models, BAG (Land Registry and Mapping Agency) and CBS (Statistics Netherlands) data, calculation results and user generated scenarios
Vision Web links grid connections to buildings from the Land Registry and Mapping Agency and uses Dutch Statistics data such as contours of neighbourhoods and districts
Interface with the calculation core to perform calculations and analyses. The calculation core has an extensive set of calculation functions for network analyses and uses parallel processing over multiple cores. In addition, it is possible to have multiple instances of the core work together for bulk calculation tasks.
With dedicated plug-ins, company-specific interfaces are possible
Vision Web is the web application of the Vision Cloud Solution, accessible via browser on PC, laptop, tablet and phone.
Vision Engine is the calculation core of the Vision Cloud Solution. It enables Vision Web to provide a large number of computational functions for network analysis.
With the API, the calculation core is accessible to external applications. The API is a REST service and is accessed via http post requests in JSON.
Company-specific interfaces are possible with dedicated plug-ins.
Vision Cloud Solution uses Vision and Gaia network files (*.vnf and *.gnf) for calculation, analysis and location .
These files are generated separately from various sources such as GIS and SCADA. A Network Builder generates a Vision of Gaia network file that is checked by a Checking Engine.
A faulty network file is an indication of data errors and is presented with extensive log information to the Data service desk. These data errors are then resolved in the source systems.
The network files successfully reviewed by the Checking Engine are stored in a Content Management System and are available for Vision Cloud Solution and the desktop applications Vision Network analysis and Gaia LV-Network Design.
Since source files and systems vary greatly from company to company, the development of the Network Builder and Checking Engine is customization.
For smaller DSOs Network Builder and Checking Engine can be desktop applications, for larger DSOs these are available in an API that runs on a server. Generating network files can then be executed fully automatically.
