Introduction: Dynamic demand models will be developed in PowerFactory and be used to represent the sizeable industrial dynamic demand service (hundreds of MW and beyond for primary and secondary frequency response) provided to the GB system. These dynamic demand models consists of a set of various dynamic demand technologies (from small-scale to large-scale with various operational characteristics), and will be integrated with the GB dynamic power system model in National Grid. The feasibility, reliability and predictability of the dynamic demand service to the GB power system will then be investigated, based on the integrated dynamic demand model and the GB dynamic power system model.

Objectives:

The key objective of this project is to develop validated dynamic demand models in PowerFactory and integrate it with the Master GB dynamic power system model in National Grid, which will provide a means for National Grid to quantify the impact of various dynamic demand technologies and gain confidence in the service provision from dynamic demand.

Expected Benefits: The success criteria for this project will include:-

• An integrated dynamic demand model and GB dynamic power system model (in the Master GB model in PowerFactory) is developed and validated.

• Results from the impact analysis of dynamic demand on balancing the GB power system are provided.

• All models to be documented in a final report.
