摘　　要：为细化负荷预测模型,基于最小二乘法建立负荷预测精度与交易时间的拟合模型。考虑可调负荷成本,提出与交易时间相关的可调负荷定价模型。考虑预测偏差惩罚价格,优化预期交易时间,使得售电公司总成本最小。仿真结果表明,相比偏差惩罚,可调负荷定价对总成本影响更大。在负荷调节电量确定时,优先选取可调负荷容量大、实际负荷调节量小、调度时间长的用户,可减小售电公司总成本。In this paper,the fitting model between the prediction accuracy and the scheduled trading interval is proposed based on the least square method,in order to refine the load forecasting model.Considering the cost of the adjustable load,its pricing model related to the scheduled trading interval is proposed.Considering the penalty price of the prediction deviation,an optimization model is proposed to determine the optimal scheduled trading interval with the least total cost of the power retail company.The simulation results show that pricing to the adjustable load has larger impact on the total cost than the penalty price.The total cost of the distribution company can be reduced by selecting the users with large adjustable load capacity,small actual load regulation and long dispatch time when the load regulation quantity is determined.
