稳格科技用电量预测算法:7天滚动预测精度达到项目要求,助力电网降低成本增效 Case Study

分用户类型建模+多源数据融合,MAPE低达到项目要求覆盖8省电网

一、项目背景与行业需求

随着电力市场化改革深化及新能源占比提升,电网企业面临电量预测精度不足导致的供需失衡、调度成本增加等挑战。传统预测模型依赖历史数据线性外推,难以应对气象突变、用户行为波动等复杂场景,尤其在工商业用户侧,用电模式多样化加剧了预测难度。稳格科技针对这一痛点,开发了基于多源数据融合与机器学习的用电量预测算法,实现7天滚动预测的高精度覆盖,助力电网企业优化调度策略、降低运营风险。

二、技术方案与核心创新

1. 多维度数据融合架构
 算法整合历史用电量、气象数据(温度、湿度、光照)、节假日信息、行业经济指标等12类特征,通过特征工程筛选关键变量,构建动态权重模型。例如,针对农业用户,增加灌溉周期、作物生长阶段等农业专属特征;对工商业用户,引入产能利用率、订单数据等经济指标,提升场景适配性。

2. 分类型精细化建模
 根据用户类型(一般工商业、大工业、居民、农业)及代理模式(直接代理、间接代理),开发8类子模型,采用集成学习技术(XGBoost+LSTM混合模型)平衡趋势预测与波动捕捉能力:

· 短期预测(1-3天):以LSTM网络为主,捕捉日内用电峰谷规律;

· 中期预测(4-7天):结合XGBoost处理气象、经济等外部因素,修正长期趋势偏差。
 通过动态权重分配机制,实现模型自适应优化。

3. 高精度评估指标体系
 采用行业权威的MAPE(平均相对百分比误差)、MAE(平均相对误差)、RMSE(均方根误差)三重指标评估模型性能,并针对不同用户类型设定差异化阈值。例如,对居民用户要求MAPE≤项目要求范围内,对大工业用户放宽至≤项目要求范围内,有助于保障资源投入与业务价值匹配。

三、应用成效与数据验证

1. 分用户类型预测精度
 8个地域的试点中,算法实现以下突破:

· 一般工商业:累计准确率保持在项目要求范围内,MAPE 项目要求范围内(样本量7),误差较传统模型有所降低;

· 代理大工业:累计准确率保持在项目要求范围内,MAPE 项目要求范围内(样本量6),满足电网调度对高波动用户的容忍阈值;

· 居民用户:累计准确率保持在项目要求范围内,MAPE 项目要求范围内(样本量6),支撑峰谷电价精准实施;

· 总电量预测:累计准确率保持在项目要求范围内,MAPE 项目要求范围内(样本量7),为全网平衡提供关键依据。

2. 7天滚动预测综合表现
 整体平均MAPE 项目要求范围内、MAE 3.91、RMSE 4.03,达到国际先进水平(IEEE标准:MAPE<项目要求范围内为优秀)。例如,在某省级电网的夏季用电高峰测试中,算法提前7天预测到工业园区用电激增,指导调度部门提前调配300MW备用容量,避免拉闸限电。

3. 业务价值量化

· 调度成本优化:减少因预测偏差导致的备用容量采购成本约项目要求范围内;

· 新能源消纳提升:通过精准预测光伏/风电出力与负荷匹配度,弃风弃光率有所降低;

· 用户服务升级:为20万工商业用户提供用电建议,助力降低较大需量电费支出超2000万元/年。

四、行业认可与标杆案例

稳格科技算法已通过国家电网公司技术鉴定,入选《电力行业人工智能应用典型案例集》,并在江苏、浙江、广东等8省电网公司推广应用。例如,在浙江某地市电网的代理工商业用户预测中,模型实现连续30天MAPE<项目要求范围内,获评“2025年度电力调度创新奖”,相关成果发表于《电力系统自动化》期刊。
