This dataset provides Sensitivity Factors (SFs) for UK Power Networks' three licence areas.\u00a0\n\nSFs represent the marginal impact of a power injection at a node on the network to branches (lines or transformers) elsewhere. They provide a simplified, linearised way of modelling the marginal impact of a MW generated in one part of the network on key constraints and are therefore widely used to model distributed energy resources (DERs) on the network. This analysis can be critical to developers assessing new projects.
\n\nThis dataset is calculated under an Import scenario of maximum demand and minimum generation. Please see the SFs (Export) dataset for sensitivity factors conducted under maximum generation, minimum demand conditions.\u00a0
\n\nSFs are calculated in PowerFactory based on an AC load flow. When calculating SFs for lines/cables/circuits, SFs are calculated between the node, which is where the import/export of power will take place, and the branch, which is where the change in power will be felt. For example, 1 MW injected at the node would have 0.8 MW decrease at the branch if the SF between the node and branch is -0.8.\u00a0 For transformers, we model between the HV node and the LV node. The SF values given are a fraction, dP/dP, that is, the increase or decrease in MW flow along the branch, resulting from a 1 MW active power injection at the node.\u00a0
\n\nThe SFs are calculated under static network conditions and in intact running arrangements. They are a useful approximation of network suitable for modelling purposes, but do not reflect the real-time variability resulting from changing running arrangements and network loading.
\n\nSFs are calculated on a per-Grid Supply Point basis: SFs are not provided between nodes and branches in different Grid Supply Points.
\n\n\nThis dataset is interoperable with our Long Term Development Statement (LTDS) publications. Nodes can be matched with LV or HV node names in Tables 2a and 2b, while branches can be linked with the lines reported in Table 1 and transformers in Tables 2a and 2b. Using these datasets, users can retrieve asset ratings to assist curtailment studies.\u00a0
\n\nThis dataset is subjected to algorithmic tests to ensure the data is clean. In addition, interoperability tests ensure that the dataset can be linked with tables from the Long Term Development Statement, also available on the Open Data Portal.
\n\nSensitivity Factors are produced by UK Power Networks engineers, based on up-to-date PowerFactory models. The data is also reviewed by DSO data scientists before publication on the Open Data Portal.
