Abstract
Abstract
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.
