The project aims to develop and trial an Active Network Management (ANM) FLM solution which improves fault level headroom utilisation in order to avoid or defer network reinforcement works and accelerate the integration of renewable generation. The project will implement and demonstrate the solution to provide alternative technical and commercial connection arrangements.

The project is split into three work packages:

Work Package 1 (WP1): AFLM Toolbox definition and modelling

Desktop-based modelling of 5 selected GSP zones will be undertaken to quantify the fault-level headroom availability across different network operating conditions. GSPs will be selected from both the SP Manweb and SP Distribution licence areas.

Monitoring devices will be installed at the proposed locations to validate the simulation work that informs the analysis. The learning will feed into the drafting of the AFLM Toolbox.

The detailed business case of the AFLM Toolbox will be developed and published. A go / no go decision to proceed with WP2 and WP3 will be made based on outcomes of WP1.

Work Package 2 (WP2): Detailed AFLM Toolbox design and testing

Refinement of AFLM Toolbox components, process and technical specification development.

Model and Manage processes will be developed and application cases will be defined. These will be subject to simulation and testing. A number of Measure and Mitigate Toolbox components will also be fully defined, configured, simulated and tested in a workbench environment prior to network demonstration.

The commercial elements of each proposition will be investigated and a report published.

A go / no go decision to proceed with WP3 will be made based on outcomes of WP2.

Work Package 3 (WP3): Network Demonstration and Learning Capture

Following design and configuration of an autonomous AFLM prototype, the solution will be tested in a live operating environment.

A project learning report will be produced outlining the operational performance during the trial. Further reports capturing the outcomes and learning of the trial will be published.

The objective of the project is to maximise utilisation of existing fault-level headroom by demonstrating the potential merits of a comprehensive AFLM toolbox combining  model + monitor + mitigate + manage approaches.

The project will be deemed successful upon delivery of the following:

Work Package 1 (WP1): AFLM Toolbox definition and modelling

Upon completion of WP1 the following deliverables will be produced:

  • GSP Fault Level Headroom Analysis Report

  • Fault Level Measurement Data Analytics Report

  • AFLM Cost-Benefit Analysis Report and Business Case Report

Subject to go/no go decision to proceed with WP2:

Work Package 2 (WP2): Detailed AFLM Toolbox design and testing

Upon completion of WP2 the following deliverables will be produced:

  • Model and Manage Process Definition, Simulation and Test Report

  • Measurement and Mitigate Solution Requirements, Design, Test Specifications and Test Report

  • AFLM Toolbox Simulation Report

Subject to go/no go decision to proceed with WP3:

Work Package 3 (WP3): Network Demonstration and Learning Capture

Upon completion of WP3 the following deliverables will be produced:

  • AFLM Toolbox Trial, Requirements and Design Specifications

  • AFLM Toolbox Solution Demonstration Report

  • AFLM Toolbox Learning Capture Report
