Abstract
This work examines energy-balancing dual port grid-forming (GFM) control for
high-voltage direct current (HVDC) transmission. In contrast to the state-of-the-art, HVDC
converters controlled in this way do not require assigning GFM and grid-following roles to
different converters. Moreover, this control enables primary frequency control and inertia
support through HVDC links. A detailed stability and steady-state analysis results in conditions
on the control gains such that i) the overall hybrid dc/ac system is stable, ii) asynchronous ac
areas are quasi-synchronous, and iii) circulating power in cyclic topologies is avoided. Finally, a
high-fidelity case study is used to illustrate and verify the analytical results Show more
