Objectives This study will be delivered across six work packages using predominantly desk based research.WP1: Establish baseline of system operation. This work package will consolidate information on current system operation and establish a baseline that will help form the basis for assessing the impact of new assets like embedded storage. WP2: Design framework to identify system risks and impacts. This work package will develop a framework building from models such as the Smart Grid Architecture Model (SGAM) to help assess the impact of embedded storage use cases. The framework will be developed as a spreadsheet-based qualitative tool that will include key parameters across the system along with acceptable excursion levels. Once the storage use cases are analysed and decomposed into the services they will carry out and the parameters they will affect (and how), the framework can then be used to help better understand where potential conflicts or issues might occur.WP3: Identify and map relevant storage use cases. This work package will focus on mapping different use cases of storage and detailed operational models within these to serve as the inputs for the next work package, which is for assessing the risks. In addition to the mapping all the current use cases, the analysis will also be forward looking i.e. what are the likely use cases that could develop in the next 5-8 years. WP4: Employ framework to assess risks. The framework developed in WP2 will be utilised here to assess the potential risks to the System Operator from the scale up of use cases identified in WP3.WP5: Prioritise use cases and risks. This work package will focus on analysing the outputs that will come out of WP4 using the framework to prioritise those use cases that could potentially create material risks for the System Operator. WP6: Recommend next steps for further exploration and mitigation of identified risks. A key aim of the project is to recommend next steps that could be carried out as further NIA projects or conducted under existing activities within the System Operator (as appropriate). The recommendations will be categorised based on the particular risk they are seeking to mitigate, e.g. improving visibility, reducing uncertainty. These recommendations will also address details such as type of partner organisations required, potential scale, objectives etc. As the GB Transmission System Operator, National Grid has visibility of transmission connected assets in terms of their presence, size and behaviour. In most cases National Grid also has mechanisms through which to influence the behaviour of these assets. However, this visibility does not extend into the distribution networks. As the GB electricity system becomes more distributed National Grids visibility of an increasing proportion of assets decreases.This is particularly true for electricity storage, a significant proportion of which is likely to be deployed within the distribution networks and operate under business models that do not exist, and so are poorly understood, today.As a result of the above, this project will focus on storage assets that are embedded within the distribution networks and with a time horizon of five to eight years to prioritise any potential risks. At the end of the project, National Grid will receive a report discussing: a list of evidence-based and realistic use cases that may require intervention by the System Operator to manage; how the impacts of these use cases may be seen bythe System Operator and the kinds of management actions required; prioritisation of which use cases may present problems in the short to medium term and why; what actions may be required to mitigate the risk of these use cases; a list of potential innovation projects that could explore specific challenge areas in more detail, for example: understanding the influencing interactions and cannibalisation of different sized devices with different objective functions and incentives forecasting the aggregate behaviour of assets in order to ensure adequate availability of reserves exploring how services could be stacked between SO and non-SO services to optimise asset value while behaving complementarily to system needs understanding data sharing requirements between aggregators and the SO in order to anticipate asset behaviour
