PMU Supported Frequency-Based Corrective Control

ICT-solutions to prevent major black outs of the grid
In order to prevent large-scale blackouts, extensive research into new applications and radical changes in the complexity of ICT is needed.

Research goal: PMU Supported Frequency-Based Corrective Control of Future Power Systems 

Electrical power systems occasionally operate close to their stability limits. Existing measurement and control schemes cannot cope with these problems.

Lack of coordinated control

A common reason for the occurrence of blackouts is:

  • lack of coordinated control when the system is affected by large disturbances

Needed: ICT

In order to prevent large-scale blackouts, extensive research into new applications and radical changes in the complexity of ICT is needed.

In future, it is expected many fossil-fuel power stations to be replaced by bulk renewables. This raises some questions:

  • What will be the frequency response of the future network after a large disturbance?
  • Will traditional preventive control actions be effective enough?
  • How can they be improved?
  • If not, will new options involving flexible real-time corrective control of conventional and renewable generation provide better solutions?

Wide-area intelligent system

In this research project, the main idea is to create a wide-area intelligent system, that empowers future power grids by:

  • providing extensive synchronised information in real-time
  • assessing system vulnerability quickly
  • performing timely corrective control actions based on system considerations

Closed-loop

The focus of this project will be on the design of a new closed-loop corrective control scheme; elimination of system frequency instability, cascading outages and catastrophic blackouts in existing and future electricity networks.

TenneT

To meet the demand to meet green energy, TenneT invested nearly 1.2 billion euros in high-voltage grids in the Netherlands and Belgium in 2015. 70% more than in 2014.

The grid reliability is ok, according to TenneT. During the eclipse in 2015, they noticed a dip of 7,000 megawatts of solar power.

Moments later again 15,000 megawatt entered the net.  The grid managed to absorb this fluctuation without any disturbances.
