【Abstract】 Currently,numerical integration methods include explicit and implicit methods.In this paper, the advantages of both methods are fused, and a good numerical explicit integration with the performance of high precision and high computation speed is proposed. The new method is faster than the current implicit numerical integration method widely used currently in the power industry. It has the same accuracy as the implicit numerical integration method. The simulation of an actual large scale system shows that the method is good in accuracy and fast in computation and can be used for online power system stability analysis. It is easy to implement. It is expected that the new method will be put into engineering use in the near future.更多还原
