| 摘要: |
| 发展了考虑负荷点停电风险的电力应急服务点的选址模型。由负荷点的缺电功率、负荷类型及停电概率确定其单位时间内的停电风险，在此基础上以各负荷点停电风险之和最小为目标建立电力应急服务点的选址优化模型，并且针对实际中电力应急时限约束可能无法满足的问题，引入超时惩罚因子对模型进行扩充。采用Floyd算法求解所发展的优化模型。算例结果表明，所提出的模型通过考虑各负荷点停电风险的差异性，在相当程度上避免了现有模型仅以应急时间最短为目标而可能造成实际停电损失较大的问题。 |

| Abstract: |
| A model for the optimal siting of power emergency service stations is developed with the consideration of power outage risk of loads，which is determined by the power shortage，load type and outage probability in unit time. The model takes the minimum total risk of all loads as its objective and introduces the overtime penalty factor into the time constraint of emergency service response when it can not be satisfied in practical conditions. Floyd algorithm is applied to solve the optimization model. Case study shows that，because the proposed model considers the difference of power outage risk among loads，the practical larger power outage cost is avoided，which may occur if only the minimum response time is taken as its objective. |
