摘　　要：分布式电源属于主动式负荷接入,会模糊电力系统时域和频域特征,导致电力系统运行状态感知效果下降,因此提出了一种新的考虑分布式电源接入的电力系统运行状态感知仿真方法。该方法采集分布式电源接入下的电力系统数据,利用采集的数据确定电力系统的时域和频域特征参数,并利用主成分分析对这些特征参数进行选择,从而保证特征提取的准确性。结合电力系统特征和极限学习机确定电力系统运行状态局部离群因子,从而实现电力系统运行状态的精准感知。Distributed power generation belongs to active load access,which can blur the time-domain and frequency-domain characteristics of the power system,resulting in a decrease in the perception of the operating status of the power system.Therefore,a new simulation method for power system operating status perception considering distributed power generation access is proposed.This method collects power system data under distributed power source access,uses the collected data to determine the time-domain and frequency-domain characteristic parameters of the power system,and uses principal component analysis to select these characteristic parameters to ensure the accuracy of feature extraction.Combining the characteristics of the power system and extreme learning machines to determine local outlier factors in the operating state of the power system,thereby achieving accurate perception of the operating state of the power system.
