Fine-grained Parallel and Multi-rate Electromagnetic Transient Simulation for Power System with Renewable Energy
摘要
Abstract
With the rapid development of renewable energy,the types of power system equipment are increasing,and the oscillation characteristics are more complex,which puts forward higher requirements on accuracy and efficiency of the electromagnetic transient simulation.A fine-grained modeling method for the power system with renewable energy is proposed based on the latency insertion method(LIM)which is used in the design of large-scale integrated circuits.Combined with the resource advantages of the graphics processor unit(GPU),the parallel solution of the algorithm is realized.The proposed method can decouple the traditional power grid and the power electronic equipment.The step sizes of sub-systems can be obtained according to the mixed numerical stability criterion and the local truncation error.Then,the multi-rate simulation of the power system with renewable energy is realized by interpolation.Finally,based on the GPU hardware platform,an improved 39-node system with renewable energy integration is taken as a case to verify the accuracy of the proposed method,and its advantages of simulation efficiency are verified by the simulation of systems with different scales and different combinations of step sizes.关键词
