Systems and methods for controlling electrical grid resources
| DWPI Title: Control system for damping inter-area oscillations, comprises damping controller that has real-time control module that receives multiple phasor measurements from multiple corresponding locations on AC transmission line in electrical grid |
| Abstract: The present invention relates to PMU-based control systems for dampening inter-area oscillations in large-scale interconnected power systems or grids to protect against a catastrophic blackout. The control systems receive phasor measurements from two or more locations on an AC transmission line and generates a power control command to a power resource on the grid. |
| Use: Control system for damping inter-area oscillations. |
| Advantage: The overall grid reliability is improved. |
| Novelty: The damping controller system 200 comprises a damping controller 230 that has a real-time control module that receives multiple phasor measurements from multiple corresponding locations on an AC transmission line in an electrical grid. A control gain module that amplifies a power command to a value that is appropriate to be injected into the electrical grid at a location where an energy resource is tied to the electrical grid. The real-time control module 232 has a summation function that compares multiple phasor measurements to construct a frequency difference signal that serves as feedback information to the real-time control module. |
