考虑电压暂降治理设备服役年限的优质供电服务模式

电压暂降治理设备存在一次性投资成本大、投资门槛高的问题，亟须一种新型优质供电服务模式解决该问题。提出一种考虑电压暂降治理设备服役年限的优质供电服务模式（HPSL）。首先，提出HPSL运营模式，明确了HPSL运营主体和服务流程，如果旧设备能够满足用户的使用需求，则使用旧设备参与治理。其次，综合考虑了设备商和用户的成本、收益构成，以双方的净收益最大为目标，建立HPSL服务定价优化模型。然后，建立基于Stackelberg博弈的服务费博弈模型，模型以设备商调整附加收益系数为决策、用户调整服务时长为响应，符合现实情况。采用改进遗传算法求解模型。最后，以某大型胶片生产厂为例进行实例分析，证明了该模式可以降低用户的治理成本，提升设备商的服务费收益。

High Quality Power Supply Service Mode Considering Service Life of Mitigation Equipment Against Voltage Sag

The voltage sag mitigation equipment has such problems as large one-time investment cost and high investment threshold, which urgently need to be solved through a new high quality power supply service mode. Therefore, a high quality power supply mode considering the service life of mitigation equipment against voltage sag (HPSL) is proposed. Firstly, a HPSL operation mode is proposed and the operation entities and service process of HPSL are defined. And it is proposed that the old equipment shall participate in the mitigation management if they can meet the user's needs. Secondly, a HPSL service pricing optimization model is established with a comprehensive consideration of the cost and income composition of equipment manufacturers and users, and with the maximum net income of both parties as objective. Furthermore, a service fee game model is established based on the Stackelberg game. The model takes the adjustment of additional income coefficient by equipment manufacturers as the decision-making, and the adjustment of service duration by users as the response, which is in line with the actual situation. The improved genetic algorithm is used to solve the model. Finally, a case study is conducted by taking a large film factory as an example. It is proved that the proposed mode can reduce the governance cost of users, and improve the service fee income of equipment manufacturers.
