系统运行影响因素不确定性的不断增强,导致现有的电力系统频率安全确定性指标已不能全面而准确地表征频率安全程度。为此,以频率最低点为研究对象提出了新的概率指标。通过对系统受扰后频率动态变化的初始条件,包括扰动所引起的有功功率缺额、扰动初始频差与系统频率响应能力等的概率分布特性及其对频率动态特性影响的分析,揭示了频率动态过程的概率分布形态。基于分析结果,遵循频率安全指标设计原则,依据低频减载损失和受扰后频率与低频减载阈值的距离,设计了两种频率安全概率指标,并给出了其计算方法及流程。仿真结果验证了所做的频率动态过程概率特性剖析的正确性,所设计的指标可以较为全面而准确地表征系统频率安全水平。
The increasing uncertainty in various influencing factors of system operation has led to the inability of existing frequency security deterministic indicators to comprehensively and accurately represent the frequency security level. Therefore
new probabilistic indicators are proposed with the frequency nadir as the research object. By analyzing the initial conditions of frequency dynamics variation after system is disturbed
including the probabilistic distribution characteristics of the active power deficit caused by disturbances
the initial frequency deviation prior to disturbances and system frequency response capability
as well as their impact on frequency dynamic characteristics
the probability distribution patterns of frequency dynamics process are revealed. Based on analysis results and following design principles of frequency security indicators
two probabilistic indicators for the frequency security are designed according to the losses from under-frequency load shedding and the distance between the disturbed frequency and the under-frequency load shedding threshold
and their calculation method and process are provided. Simulation results validate the correctness of the probabilistic characteristic analysis of frequency dynamics process
and the designed indicators can comprehensively and accurately represent the system frequency security level.
