Abstract
The present disclosure relates to systems and methods for controlling and compensating reactive power consumption in an electricity distribution network by means of one or more power converter devices. Each power converter device may be configured to provide active power to a respective power consumer such as a mechanical load. The systems and methods herein further pertain to mitigating voltage harmonic components in the electricity distribution network by means of the one or more power converter devices. A distributed control system comprising a plurality of power converter devices for counteracting reactive power consumption and/or harmonic mitigation in the electricity distribution network has also been disclosed.
Claims20
A power converter device configured to be connected, and provide electric power to a power consumer device comprised in an electricity distribution network;
- wherein the power converter device comprises or is in communication with a control unit configured to:
- estimate, based on data representative of one or more real-time characteristics of the electricity distribution network, a reactive current indicator parameter associated with a total reactive power consumption by one or more electricity consumer devices external to the power consumer device and connected to the electricity distribution network;
- and
- calculate a corresponding reactive power compensation current based on the determined reactive current indicator parameter to counteract the reactive power consumption in the electricity distribution network;
- wherein the power converter device is configured to receive a first control signal from the control unit causing the power converter to:
- generate a corresponding reactive power compensation signal based on the calculated reactive power compensation current without compromising delivery of electric power to the power consumer device.
A computer-implemented method for controlling reactive power consumption in an electricity distribution network, wherein the method is at least partly implemented in a power converter device configured to be connected, and provide electric power to a power consumer device comprised in the electricity distribution network;
- wherein the power converter device comprises or is in communication with a control unit;
- wherein the method comprises:
- determining based on data representative of one or more real-time characteristics of the electricity distribution network, a reactive current indicator parameter associated with a total reactive power consumption by one or more electricity consumer devices external to the power consumer device and connected to the electricity distribution network;
- calculating a corresponding reactive power compensation current based on the determined reactive current indicator parameter to counteract the reactive power consumption in the electricity distribution network;
- receiving a first control signal from the control unit at the power converter device;
- and
- upon receiving the first control signal:
- generating a corresponding reactive power compensation signal based on the calculated reactive power compensation current without compromising delivery of electric power to the power consumer device.
