摘要

为考虑新能源不确定性、波动性等特点对电力系统静态电压稳定边界（SSVSM）的影响,以蒙特卡洛抽样方法为基础的传统做法需反复多次调取连续潮流获取SSVSM,计算效率低。寻求一种能兼顾计算效率和准确性的SSVSM计算分析方法具有重要的意义及价值。该文提出一种基于全导数算法的仿射区间方法,以计算考虑系统在不稳定功率源影响下SSVSM的波动范围。借助IEEE标准输电系统,采用同型算法进行对比,证明了所提算法的高效及准确性。

Abstract

To address the impact of the uncertainty and volatility of new energy on the steady-state voltage stability margin （SSVSM） of power systems, conventional methods often rely on the Monte Carlo method, which requires repeatedly invoking continuous power flow calculations. This process is computationally inefficient. Therefore, it is of great significance and value to develop a steady-state voltage stability analysis method that balances computational efficiency and accuracy. The paper proposes an affine interval method based on the full derivative direct method to calculate the fluctuation range of the SSVSM affected by intermittent power sources in the system. Using IEEE standard transmission systems for case studies and comparative experiments with similar algorithms demonstrate the high efficiency and accuracy of the proposed method.
