Special Session Information:
The renewable energy generation (REG) in new power systems has dramatically increased all over the world. Hence, renewable energy should be operated and controlled synergistically with the traditional sources to improve the frequency security and stability. In these cases, REGs should participate in the frequency regulation and control as a principal character. However, the frequency stability regulation and control technology have obstacles by the following challenges:
1) The REG unit and stations are arduous due to the volatile and random operating points, as well as the nonlinear and multi-time scale dynamics;
2) The frequency stability modelling of new power systems with REG is perplexed by the electromagnetic-electromechanical interaction and the spatial-temporal coupling dynamics;
3) The dimension and complexity of frequency stability control are increased due to the coupled effect of the source, grid, load, and storage with distinct characteristics.
Hence, to fully explore the frequency security in high-penetration renewable energy power grids, novel solutions and techniques need to be researched.
