The key objectives are to reduce operational costs and to enable increased system access for asynchronous generation types including renewable generation (wind, solar).
If measures are not taken to ensure distributed generation is less susceptible to RoCoF events, then increased operating costs are likely to result through the curtailment of large infeed risks or the operation of synchronous generation in favour of asynchronous generation to manage RoCoF risks. Potential increases in system operating costs by 2018/19 are forecast to be 250m per annum, rising to in excess of 1000m per annum by 2025.

Expected Benefits:
  • The provision of a comprehensive GB wide model (by DNO) for distributed generation installations of (5MW including the generation and loss of mains protection types.)
  • A risk assessment that will enable decisions to be made on changes to protection settings on existing generation and what protections and settings should be used for further distributed generation.
Abstract The work will provide a comprehensive view of distributed generation types and susceptibility to RoCoF for the entire GB synchronous network. The feasibility and implications of using revised protection settings to avoid coincident distributed generation losses during loss of infeed events will be established.
