Abstract: The invention relate to method of controlling a flow network comprising pressure controlling means adapted to regulate a pressure difference of a fluid over two locations in the flow network according to a pressure setting,
a controller adapted to adjust the pressure setting and to track a physical value in the system, the method being for the controller to operate
- at a normal load mode where the pressure controlling means is set at a basic pressure setting when the physical value is within a first threshold range, and
- at a unstable load control mode including a change of the pressure setting to a unstable load pressure setting when it a gets outside said first threshold range.
The invention further relate to the controller itself adapted to operate accordingly.
