Abstract
本申请公开了基于线路传输限额分档切换的电力系统调度方法、装置、设备及介质，涉及电力系统运行技术领域，包括：构建连续时间经济调度模型，并通过Bernstein多项式插值转换为有限维线性规划模型；对样本集进行潮流计算与校核，结合新能源与负荷历史数据，通过聚类划分运行方式类型确定特征中心，采用支持向量机分类器识别稳定‑失稳边界，剔除不稳定样本，对剩余样本的功率区域进行网格划分，将各网格功率最大值设为线路传输限额；计算新能源与负荷曲线随时间与各特征中心的距离，依据时变距离确定类别切换时间点，以划分为子区间，选取距离最近的子类型的限额最小值为时段限额，以生成调度方案，提高电力系统调度的效率与可靠性。
