“…DC system frequency modulation uses frequency deviation as input to rapidly adjust the active power transmitted by the DC system to suppress the frequency change of the AC system, which is divided into unilateral frequency modulation and bilateral frequency modulation [6][7]. For the model of Equation ( 1), ignoring the influence of dead zone, we only need to attach a DC power modulation quantity ∆P mod to the power fixed P dset .…”

For a multi-DC interconnected asynchronous power grid, to quickly evaluate the steady-state frequency after DC blocking, a fast evaluation method is proposed in this paper. Firstly, the power flow model was established, including the DC transmission system, each interconnected asynchronous power grid model. The steady-state operation state before DC blocking was solved. Secondly, considering the adjustment of the model after DC blocking, the steady-state frequency analysis model considering the effects of primary frequency regulation and various stability control strategies was established. Finally, a case study was used to confirm the effectiveness of the proposed method. The simulation results and analysis show that the proposed method is fast and accurate.
