【摘要】：为快速有效地评估大规模风电并网电力系统的静态安全水平,将随机潮流引入安全评估。以解析法随机潮流为电网状态分析手段,保证方法高效性,并基于序列运算理论实现随机潮流计算,降低了对分析所需基础数据的要求,以保证方法实用性。定义了基于随机潮流结果的安全指标,从概率和风险两个角度快速实现系统安全的综合量化评价。基于元件级安全指标进一步给出了系统薄弱环节辨识方法。IEEE-RTS79系统测试结果验证了所提方法的有效性和准确性。与传统不确定性评估方法相比,所提方法能大幅提高评估效率,对间歇性能源并网电力系统的安全评估具有实用价值。
[Abstract]:In order to evaluate the static safety level of large-scale wind power grid power system quickly and effectively, stochastic power flow is introduced into safety assessment. Taking the analytic random power flow as the power network state analysis method, the efficiency of the method is guaranteed, and the random power flow calculation is realized based on the sequence operation theory, which reduces the requirement of the basic data needed for the analysis and ensures the practicability of the method. The safety index based on stochastic power flow results is defined, and the comprehensive quantitative evaluation of system security is realized quickly from two angles of probability and risk. Based on the component level safety index, the system weak link identification method. IEEE-RTS79 system test results verify the effectiveness and accuracy of the proposed method. Compared with the traditional uncertainty assessment method, the proposed method can greatly improve the evaluation efficiency, and has practical value for the safety evaluation of intermittent energy grid connected power system.
