Currently the Long Term Development Statement (LTDS) and Week 28 (annual report to National Grid) reports are being generated using a variety of software tools, including the network modelling tools Distribution Network Information System (DINIS) and Power System Simulator for Engineering (PSS/E). Information was extracted from these tools and processed in MS Excel to prepare the final report.
This project was initiated to investigate if automating the production of LTDS and week 28 reports is possible with the same structure for all the DNO licence areas. As part of this project, a set of professional schematics for the LTDS, and an automatic report for Week 28 are developed within the existing modelling tool – Digsilent PowerFactory.

This project aims to address the following issues:

  • Multiple tools for LTDS and Week 28 reporting

  • The complex calculations involved are prone to human errors

  • Takes a two person year effort for the production of reports once a year.
