An entropy-method-based large-power customer electricity charge recovery risk assessment method

The invention discloses an electric power large customer electricity charge recovery risk assessment method based on an entropy method, and the method comprises the steps: building an electric power large customer electricity charge recovery risk index system based on the internal electric quantity and electricity charge data of electric power and combining the business, tax administration and court information related to an enterprise; performing customer electricity charge recovery risk assessment by adopting an entropy evaluation method, and dividing customer risk levels according to risk score distribution; and for high-risk customers, carrying out actual situation verification, verifying the effectiveness and the distinction degree of the risk assessment index and the risk assessmentmethod, and the electric charge recovery risk of the high-power customers can be effectively early warned. 本发明公开了一种基于熵值法的电力大客户电费回收风险评估方法，基于电力内部的电量、电费数据，结合企业相关的工商、税务、法院信息，建立电力大客户的电费回收风险指标体系；采用熵值法进行客户电费回收风险评估，并根据风险评分分布划分了客户风险等级
