摘要：

When the load flow of large-scale power system is solved by the existing holomorphic embedding load flow method，the order of power series is too high，which easily causes divergence of analytic extension，poor convergence and high computational redundancy. A novel constant values and priori buses based holomorphic embedding load flow method is proposed. A constant values based holomorphic embedding load flow model is built，and the load flow convergence is improved by dynamically updating constant values. A pre-judgement mechanism of voltage amplitude of priori buses is proposed to improve the computational efficiency. Two bus-type conversion strategies are proposed. The proposed method is analyzed and verified by the test systems with different scales，and results show that the proposed method is independent on the initial value，can accurately and efficiently solve the load flow solution，and has better load flow convergence than Newton-Raphson method and traditional holomorphic embedding load flow method. © 2023 Electric Power Automation Equipment Press.
