Abstract:

随着智能电网技术的发展,配网侧将接入大量风机,传统负荷模型不能很好地描述负荷特性。以含有风电的广义负荷建模为目的,提出了含有风电的广义负荷模型结构,只需在综合负荷模型(syntheticloadmodel,SLM)的虚拟母线上增加1台异步发电机。提出了参数辨识策略先通过统计综合法得到聚合模型参数,然后采用总体测辨法,将低灵敏度参数、非时变参数固定为聚合值,对于高灵敏度且时变参数采用遗传算法在聚合值附近进行参数辨识。只辨识电动机的定子电抗、电动机比例、电动机初始负载率、风力发电相对纯负荷的比例、配电网络电阻、配电网络电抗共6个参数。通过对风机3种接入位置进行仿真表明,上述模型结构的描述能力、泛化能力和辨识结果的稳定性较好。
