Objectives An advanced model of the most relevant part of the GB grid will be used which will be suitable for deriving quantitative operational guidance for this part of the grid. This will be done by:i) Replacing many of the generic converter models with manufacturer-provided models.ii) Using a more complete model of the wider British grid network. In addition, work will be undertaken to research how the use of advanced models can be made more practical:iii) Providing guidance on how ESO should use this type of advanced model.iv) Investigating tools that help indicate where advanced models and more detailed stability analysis are necessary. The work is to comprise: Obtaining suitable high-fidelity models of converters in the area of interest and integrating these into a suitable advanced model for stability simulations. Drawing conclusions regarding the implications for future grid security and grid modelling. Providing “guidance notes” for ESO on the use of advanced models and techniques for conducting detailed stability analysis. Investigating tools that would give “early warning” of situations on the grid where advanced modelling techniques and detailed analysis might be required to ensure stability. Investigating whether the representation of grid demand needs to be upgraded. Validating the conclusions of NIA_NGET0187 regarding grid stability. Research into practical tools for the application of advanced grid modelling for system operations.
Abstract The proportion of power that is injected into the GB grid via AC/DC converters is rising rapidly: modern wind turbines, battery storage, solar farms and HVDC links all use this technology. The previous NIA project Transient Voltage Stability of Inverter Dominated Grids and Options to Improve Stability (NIA_NGET0187) identified that at high levels of converter use certain parts of the grid can become vulnerable to a new form of instability following fault conditions considered to be credible by the SQSS. This instability, which is caused by the way that the control systems within the converters operate, needs to be properly identified in ESOs studies if Britains current high level of supply reliability is to be maintained.The objectives of this project: Validating the conclusions of NIA_NGET0187 regarding grid stability. Research into practical tools for the application of advanced grid modelling for system operations.
