The hybrid ac-dc systems topology merely enabling the incorporation of ac-dc energy sources, loads, and converters typically compose the promising configurations for future smart grids and sustainable transportation. However, the key challenge of intelligent design, planning, and efficient operation for such hybrid acdc systems traditionally rely on the powerful and efficient power flow algorithm, independent of iterative methods. The conventional sequential and unified approaches to solve power flow equations are initial choice dependent and fail to converge in case of the inappropriate choice. For this apparent reason, this paper proposes a novel and reliable, unified holomorphic embedding power flow method (unified- HEPM) to accurately evaluate the power flow solution. The verification and validation of the proposed unified-HEPM are sufficiently illustrated by considering modified four buses ac-dc hybrid system including converters.
