dc.description.abstract | This paper proposes a new decentralized strategy for optimal grid frequency regulation (GFR) in an interconnected power system, where onshore grids and offshore wind farms (OWFs) are linked using a multi-terminal high-voltage direct-current (MTDC) system. In the proposed strategy, grid- and OWF-side optimal controllers are developed to coordinate the operations of synchronous generators and the MTDC converter, and the OWF and the MTDC converter, respectively, thus achieving optimal generator power and deloaded OWF power sharing of the interconnected grids and minimizing frequency deviations in each grid. Full-order dynamic models of an MTDC-linked grid and an OWF are implemented, and given each dynamic model, grid- and OWF-side decentralized linear quadratic Gaussian regulators are designed for optimal GFR of the MTDC-linked grids and supporting GFR through optimal deloading operation of the OWFs, respectively. Eigenvalue analyses are conducted with a focus on the effects of system parameter uncertainties and communication time delays. Comparative case studies are also performed to verify that the proposed strategy improves the effectiveness and stability of real-time GFR in MTDC-linked grids under various conditions. | - |
