Assessment of Distributed Generation Behaviour during Frequency Disturbances: Closure Report

Abstract:

<p>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.</p> <p>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 &#163;250m per annum, rising to in excess of &#163;1000m per annum by 2025.</p> <p> Four reports have been provided detailing the outcomes of the project.</p> This report covers the project's: <bl> <li>Scope</li> <li>Objectives</li> <li>Success Criteria</li> <li>Performance Compared to the Original Project Aims, Objectives and Success Criteria</li> <li>Required Modifications to the Planned Approach During its Course</li> <li>Lessons Learnt for Future Projects</li> <li>Outcomes</li> <li>Planned Implementation</li> <li>Other Comments</li> </bl>
