- Abstract
When the holomorphic embedding load flow calculation method is used to solve the load flow of power system, if the initial points of voltage power series of flat start are far away from the actual values of load flow solution of the system, the calculation amount is easy to increase. Moreover, the calculation time based on the traditional central processing unit (CPU) serial calculation architecture is too long in the process of solving the voltage of each node. A holomorphic embedding load flow parallel calculation method based on the adaptive power series initial points is proposed. The initial points of holomorphic embedding load flow of the system are adaptively adjusted according to the node admittance matrix of the system and the voltage of equilibrium node, a calculation model of holomorphic embedding load flow based on the initial points of adaptive power series is constructed to accelerate the convergence of voltage power series. Based on the multi-core CPU calculation platform, the parallelization of voltage Padé approximation for each node is realized to improve the solving efficiency of load flow equation of the system. The simulative results of different scale test systems show that the proposed method can realize efficient and accurate solution of holomorphic embedding load flow of power system.
