摘要

在系统中留有一定的发电备用容量是确保电力系统安全可靠运行的重要措施之一。文中建立了考虑发电备用容量的输电网规划模型。该模型以线路投资成本最小为目标，引入任意一台发电机故障时系统的安全性约束以确保该故障下系统的发电备用容量可以被充分利用从而维持系统的安全性;引入网络可用传输能力约束以确保负荷增长时系统的发电备用容量能够有效传输到负荷点从而维持系统的安全性。使用改进的贪婪随机自适应搜索算法求解新模型。6节点、46节点系统算例的计算结果验证了所述方法的正确性和有效性。

Abstract

Retaining certain percentage power reserve is one of the most important measures to ensure the safety and reliability of the power system. With the minimization of transmission investment as objective， a new transmission network planning model considering the power reserve is proposed. Two types of constraints are taken into account: one is that the power reserve can be used when any generator is outaged; the other is that the power reserve can be transferred to maintain the safety of the system in the case of uncertain load increasing. An improved greedy randomized adaptive search algorithm is used to solve the model quickly and effectively. Simulation results on the 6-bus system and 46-bus system validate the new method.
