Introduction: This programme of work consists of the following projects:

• SuperGUM

• Control System Model Development for existing stations to avoid system reinforcement

• Model development for new HVDC plant

• Risk Managed Corrective Control of Electricity Transmission

• Harmonic Data Gathering

• Voltage transducers for power quality measurements

• Impact of future generation plant on system stability and frequency control.

The issue addressed by this programme is the connection over the coming years of large scale renewable and low carbon generation and ensuring any possible technical barriers are overcome in good time.

Objectives: The overall objective of this programme of work is to ensure the smooth integration of large scale renewable and low carbon generation into the GB power system. This includes the development of various models to assist in planning and designing the system. SuperGUM is being developed by Strathclyde University. This is a development of the existing Generator Uncertainty Model (GUM) for probabilistic generation planning. The development of validated excitation system models for existing power stations for use in power system analysis and the development of dynamic models for new HVDC plant aim to facilitate the future integration of HVDC connections to the system.

A further project researching risk managed corrective control aims to deepen the understanding of the risk of major loss of supply to NGET as well as improve understanding of those investments that promise to be most effective in managing these risks. It will also help to identify an appropriate means of efficiently utilising quadrature booster transformers and other series control devices, taking due account of risks of major loss of supply.
