摘要
提出一种考虑不确定因素的电力系统静态安全的预防控制方法。首先,给出一种考虑预想事故发生概率和负荷水平不确定性的系统静态安全指标;然后通过将该指标加入到预防控制模型中,得到考虑不确定因素的预防控制策略,重点考虑采用发电机出力再调整和切负荷作为控制手段。鉴于负荷特性对系统的影响很大,采用ZIP负荷模型。我国某实际系统的仿真算例结果验证了所提方法的有效性。
An algorithm of static security preventive control is proposed consideration of uncertainty factors. A static security index of power system is for power system with the proposed,which,considers the probability of pre-defined contingencies and the uncertainty of load level. The preventive control strategy is obtained by adding the index into the preventive control model,which emphasizes the generator rescheduling and load shedding. For the large influence of load characteristics on system,the ZIP load model is adopted. The simulative result of a practical domestic system verifies its effectiveness.
