| 摘要: |
| 针对极端灾害提出了考虑线路故障概率的电力系统预防-紧急协调调度方法。以预防阶段和紧急阶段综合失负荷成本最小化为目标，建立考虑线路故障率的电力系统防御-攻击-防御3层优化调度模型。其中，预防阶段的发电机出力调整、网络拓扑切换和负荷减载以及紧急阶段的发电机再调度、紧急负荷切除被建立为防御资源，线路故障率被纳入攻击资源的建模中。采用列与约束生成算法对该模型进行求解，将3层模型转化为双层混合整数线性规划问题，通过IEEE-RTS-24节点系统进行算例仿真验证了所提方法的有效性，结果表明：在预防阶段采取调度措施作为主要防御手段能够有效降低负荷损失；在预防-紧急协调决策优化过程中考虑线路故障率能够有效降低预防成本，提升预防效果。 |

| Abstract: |
| The preventive and emergency coordinated dispatching method of power system considering line failure rate is proposed for extreme disasters. The three-level optimal dispatching model of defense-attack-defense for power system taking the line failure rate into account is established with the objective of minimizing the integrated load loss cost in the preventive and emergency stages. In this regard, the generator output adjustment, the network topology switching and the load shedding in the preventive stage, and the generator re-dispatching and the emergency load shedding in the emergency stage are built as defense resources, whereas the line failure rate is included in the modeling of attack resources. The column and constraint generation algorithm is applied to solve the model, transforming the three-stage model into a two-stage mixed-integer linear programming problem. The effectiveness of the proposed method is verified by case study simulation based on the IEEE-RTS-24 bus system. Results show that the load loss is reduced effectively in the preventive stage when dispatching measures are adopted as the main defense means, meanwhile the preventive cost is reduced effectively and the preventive effect is improved by considering the line failure rate in the optimization process of preventive and emergency coordinated decision. |
