电费拖欠风险的混合预测模型
首发时间:2019-04-30
摘要:电网公司的经营模式是"先用电-后付费"。高压用电客户耗电量大,每月产生的电费占70%以上,存较大的潜在电费回收风险。如果缴费违约,将会给电力公司带来难以弥补的损失,本文首先筛选影响电费拖欠的7个主要因素,然后采用神经网络预测高压客户的风险得分值,再用风险得分值与7个主要影响因素建立逻辑回归预测高压客户的风险,将风险管理模式由劳动密集型向技术型转变,及时预警高风险用电客户。实验证明本文建立的神经网络与逻辑回归的混合预测模型有较高的预测精度,与实际情况具有良好的一致性,避免高压用户因违约给电力公司带来难以补救的损失。

Hybrid Prediction Model of Electricity Default Risk
Abstract: The operation mode of power grid companies is "use electricity first -- pay later". High-voltage customers consume a lot of electricity, which accounts for more than 70% of the electricity generated every month. Therefore, there is a great potential risk of electricity charge recovery. If the payment defaults, the power company will be difficult to make up for the loss. This article first screening out the seven main factors influencing the electricity arrears, and then use the neural networks to predict high-pressure customer risk score values. After that, we combine the risk score values and seven main influence factors to establish a logistic regression, predicting high-pressure customer risk. By doing so, we change the risk management model from a labor intensive model to a technical one, timely warning high-risk power customers. The experiment proves that the mixed prediction model of neural network and logistic regression established in this paper has high prediction accuracy and good consistency with the actual situation, so as to avoid the power company\'s losses caused by high voltage users\' breach of contract.
Keywords: Risk Prediction, Neural Network, Logistic Regression, High Voltage Customers, Power Grid.
