Efficient Power System Transient Simulation Based on Frequency Response Optimized Integrators Considering Second Order Derivative
摘要：
本文提出了一种考虑二阶导数的频率响应优化积分器。基于所提出的数值积分器，以及其他考虑二阶导数的数值积分器，提出了一种新的电力系统暂态仿真方案。该仿真方案不使用唯一的数值积分器，而是根据微分状态变量的主频分量选择合适的数值积分器。与建议的模拟计划，提高了计算效率，通过使用大的步长，而不牺牲精度。数值算例验证了该方法的有效性。
英文摘要：
Frequency response optimized integrators considering second order derivative are proposed in this paper. Based on the proposed numerical integrators, and others which also consider second order derivative, this paper puts forward a novel power system transient simulation scheme. Instead of using a unique numerical integrator, the proposed simulation scheme chooses proper ones according to the dominant frequency component of the differential state variables. With the proposed simulation scheme, computational efficiency is improved by using large step sizes without sacrificing accuracy. Numerical case studies demonstrate the validity and efficiency of the simulation scheme.
