Abstract

Burning fossil fuels for power generation is one of the highest sources of pollution around the world. Governments have committed to carbon reduction targets to reduce the rate of environmental damage occurring. To achieve these goals low or zero carbon emitting renewable energy resources are being installed on networks which displace legacy synchronous generation.

Historically the power system has had a high level of power system inertia as the network contains multiple synchronous generators in lock step with other, maintaining the power frequency, providing system stability, and keeping the balance between power generated and load power. An unknown variable is what the impact of renewable resources will have on the system inertia as, due to their design, they provide little to no inertial response to system disturbances.

This project aimed to develop a method for transmission network system operators to assess system inertia in real time. Different methods of achieving this were examined. The final product of the research lead to the development of a sliding discrete Fourier transform that monitors the voltage waveform. This can be simply implemented on existing network infrastructure and works independently without requiring any load of generation information.
