Operation of large power systems with small amounts of physical inertia
The introduction of renewable electricity production results in a reduction of the amount of inertia available to maintain the system stable after the loss of a large production unit. A similar development has taken place in the 16-Hz subtransmission system for railway traction in Sweden due to the replacement of rotating converters by static converters.
This project aims at mapping and quantifying the concrete limits to the operation of such system due to the lack of physical inertia. The project will further study the possibilities of using electronic inertia. Measurements will be performed on the behaviour of traction power system during significant unbalances between production and consumption.
