Abstract

Ensuring the power supply of important special loads can effectively reduce the electric power losses resulted from disaster. A model and method of power grid differentiated planning are proposed for the consideration of special loads power supply under disaster. By introducing the probability of the electric power equipment damage in disaster, the power grid differentiated planning model on the basis of supplying power for the special loads is proposed which optimizes the outage losses and the added generation cost. Two different types of power supply for special loads are taken into account. The one ensures the full capacity of each special node, and the other ensures part capacity of the each special node because only part capacity of the node is urgent. The simulated results of IEEE 14-bus and IEEE 118-bus system demonstrate the rationality of the proposed model, which offers reference to the anti-disaster planning in power systems.
灾备差异化规划,保障特殊负荷供电
保证重要特殊负荷的供电,可以有效减少灾害造成的电力损失。提出了一种考虑灾害条件下特殊负荷供电的电网差异化规划模型和方法。通过引入灾害中电力设备损坏的概率,提出了基于特殊负荷供电的电网差别化规划模型,优化了停电损失和发电附加成本。考虑到特殊负载的两种不同类型的电源。一种是保证每个特殊节点的全部容量,另一种是保证每个特殊节点的部分容量,因为每个节点只有部分容量是紧急的。对IEEE 14总线和IEEE 118总线系统的仿真结果验证了所提模型的合理性,为电力系统的防灾规划提供了参考。
