This project seeks to challenge current curtailment arrangements by creating a new post fault capability for overhead lines and a new ANM architecture which will help to avoid curtailment. An improved system of short term dynamic OHL ratings (informed by real-time conductor temperatures) and a new corresponding ANM control system architecture will be the key outputs of this work. This project will be delivered in five concurrently run stages as shown below:Work Package One: Consideration of changes required to the ANM Control System ArchitectureWP1 will review existing ANM scheme arrangements and will establish whether there are any planned upgrades to ANM systems and their timeframes. Once this step is successfully completed, WP1 will identify gaps in the existing ANM system arrangements and will map out changes required for ANM to support a new short-term post-fault ratings to supplement existing seasonal static ratings. Consideration will be given to failover arrangements of the ANM system if conductor temperature monitoring information becomes unavailable, for example, gracefully reverting to seasonal static post-fault ratings. The output of WP1: will include a technical document outlining the functional changes required to the existing ANM system architecture. Work Package Two: Short-term post-fault ratings and risk assessment.WP2 will build on the high-level technical implementation of a short-term post-fault rating delivered under OHL Power Pointer project. This approach will deliver a set of requirements (in a technical specification) for a short-term post-fault rating suitable for use in a live operational environment. The output of WP2: will be an updated specification for the derivation of a short-term post-fault OHL rating. A risk assessment document specifying the risks of the application of short-term post-fault ratings and available risk mitigation measures which could be adopted.  Work Package Three: Development of Network Use Case and Power System Studies.WP3 will define representative network use cases comprising areas of the network. Network use cases will consider different conductor characteristics, mixed composition circuits (including underground and overhead cable sections), availability of the conductor temperature monitoring system, etc.Power system studies utilising the network use cases will be undertaken to quantify the maximum capacity that can be released (in MWh) if the ratings derived from historic data[1
