电压暂降保险机制的量化分析

Quantitative Analysis on Insurance Mechanisms for Voltage Sag

随着售电市场的不断放开,竞争被引入了售电环节,提供电力客户用电满意度高的优质供电服务就显得格外重要,电压暂降保险机制正是提高用户满意度的一种有效方法。在分析电压暂降损失风险特点的基础上,对控制型和财务型两种损失风险管理方式进行了对比分析;在财务型风险管理方式的理念下,建立了三种电压暂降保险机制;引入灰色系统理论,综合电压暂降损失风险事件各利益相关方的意见对不同保险机制进行定量评估,得出可行性最高的电压暂降保险机制。最后,对中国某高新技术园区内三家高端制造企业进行实证分析,证明了该方法的合理性和适用性。

With steady liberalization of the electricity market,competition has been introduced into the sale of electricity.Providing quality customers with quality power supply service appears to be particularly important.The voltage sag insurance mechanism is exactly an effective way to improve users＇satisfaction.Based on an analysis of the loss risk characteristics of voltage sag,the control type and financial type loss risk management modes are compared and discussed.Three voltage sag insurance mechanisms of financial risk management mode are set.By introducing the grey system theory and making comprehensive quantitative assessment of different insurance mechanisms through synthesizing the views of different entities,the most suitable and feasible insurance mechanism for the loss risk of voltage sag has been obtained.Finally,according to an empirical analysis of three high-tech customers in a high-tech park in China,the applicability and rationality of the method is proved.
