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 ESO’s studies if Britain’s 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.
