Modelling UK power system frequency response with increasing wind penetration

This paper looks into the modelling of frequency response of the UK power system, showing the transient effects in different scenarios. As the UK pursues its renewable energy target, predominantly through offshore wind, the UK´s TSO, National Grid, has to facilitate for a grid with reduced inertia and predictability, in conjunction with changing infeed-loss requirements. A validated model of the UK system is used to identify the future requirements for primary and secondary response to maintain frequency control for grid code compliance, and the benefits of synthetic inertia from wind turbines. The model shows how the primary response needs to be changed to effectively deal with increased infeed-loss requirements in low demand and high wind penetration scenarios.
