摘要

针对含可再生能源电力系统中概率性潮流分析效率低且不能从整体角度反映波动对系统影响的问题,提出一种基于静态安全域理论的改进概率潮流分析方法。首先采用基于最大熵法的潮流算法计算并分析测试系统的概率潮流情况;然后通过有效边界辨识方法和静态安全距离指标分析可再生能源概率性波动对测试系统静态安全的影响。最后通过对新疆哈密区域电网进行分析,验证了所提方法的可行性和实用性。

Abstract

Aiming at the problem that the original probabilistic power flow analysis method of electric power systems with renewable energy is inefficient and cannot reflect the impact of fluctuations on the system as a whole, this paper proposed an improved probabilistic power flow analysis method based on steady-state security region theory. Firstly, the probability power flow of the tested system is calculated by the maximum entropy methods. Furthermore, the influence of the probability fluctuation of renewable energy on the steady-state security of the tested system is analyzed by the effective boundary identification method and evaluated by the steady-state security distance index. Finally, the feasibility and practicability of the proposed method are verified by analyzing Hami regional power grid in Xinjiang.
