Abstract
There is provided a computer-implemented method of controlling a bipole power transmission network, the method including: receiving an indication of a disturbance in a first AC system; and then controlling first and second power converters of the bipole power transmission network to provide substantially the same active power at their respective first and second AC sides.

A computer-implemented method of controlling a bipole power transmission network, the bipole power transmission network comprising a first power conversion means comprising first and second power converters having respective first and second alternating current ‘AC’ sides and respective first and second direct current ‘DC’ sides, a second power conversion means comprising third and fourth power converters having respective third and fourth AC sides and respective third and fourth DC sides, a first power transmission means electrically connected between the first and third DC sides and defining a first electrical pole having a first DC voltage and a first DC current, a second power transmission means electrically connected between the second and fourth DC sides and defining a second electrical pole having a second DC voltage and a second DC current, wherein the first and second AC sides are connected to a first AC system, wherein the third and fourth AC sides are connected to a second AC system, the method comprising:
- receiving an indication of a disturbance in the first AC system;
- and then
- controlling the first and second power converters to provide substantially the same active power at their respective first and second AC sides.
A controller for controlling a bipole power transmission network, the bipole power transmission network comprising a first power conversion means comprising first and second power converters having respective first and second AC sides and respective first and second DC sides, a second power conversion means comprising third and fourth power converters having respective third and fourth AC sides and respective third and fourth DC sides, a first power transmission means electrically connected between the first and third DC sides and defining a first electrical pole having a first DC voltage and a first DC current, a second power transmission means electrically connected between the second and fourth DC sides and defining a second electrical pole having a second DC voltage and a second DC current, wherein the first and second AC sides are connected to a first AC system, wherein the third and fourth AC sides are connected to a second AC system, the controller comprising:
- a memory;
- and
- at least one processor;
- wherein the memory comprises computer-readable instructions which when executed by the at least one processor cause the controller to:
- receive an indication of a disturbance in the first AC system;
- and then
- control the first and second power converters to provide substantially the same active power at their respective first and second AC sides.
