IEEE Power and Energy Magazine
Year: 2024 | Volume: 22, Issue: 2 | Magazine Article |
Cited by: Papers (6)
The primary objective of electricity grids is to reliably meet the electricity demand at a minimum cost. This objective can be broken down into a set of needs that are met through services. These services are procured by mandating them either in grid codes or via market mechanisms. While grids in different countries/regions share common features in terms of needs and services, there are variations...Show More

Analytical Design of Contributions of Grid-Forming and Grid-Following Inverters to Frequency Stability

Eugenie A. S. Ducoin;Yunjie Gu;Balarko Chaudhuri;Timothy C. Green

IEEE Transactions on Power Systems
Year: 2024 | Volume: 39, Issue: 5 | Journal Article |
Cited by: Papers (9)
Most of the new renewable generation in power systems is connected through Grid-Following inverters (GFL). The accompanying decline of fossil-fuelled synchronous generation reduces the grid inertia. As these two trends progress, instabilities become more likely. To allow more renewables onto the grid, the use of combinations of GFL and Grid-Forming inverters (GFM) has been proposed, however, it is...Show More
