【摘要】：网络阻塞和故障停运导致备用存在供应问题,为了保证含多分区电力系统备用的有效性和网络的安全性,在实时优化调度中提出分区备用要求和新的求解算法,分析了含多分区的孤立和受端电力系统备用容量需求,建立了一种以电能和备用购买费用最小为目标函数的能量备用实时优化调度模型,同时计及了系统备用要求、分区备用要求、N-1安全准则等约束条件。该模型是一个超大规模的优化问题,因此文中将动态积极集法引入电力系统优化调度问题,对其进行迭代求解。最后,对IEEE 118节点标准测试系统和我国某典型受端电网进行算例分析,结果表明,采用提出的实时优化调度模型和动态积极集求解算法在满足电力系统实时调度计算时间要求的同时,求解得到能量备用的实时优化调度方案以及N-1故障后备用调用方案,验证了模型的合理性和算法的可行性。该算法可以有效解决备用的供应问题,提高电网运行的安全性,为含多分区电力系统的实时优化调度提供有意义的探索。
[Abstract]:In order to ensure the effectiveness of standby and the security of the network in power system with multiple partitions, a new algorithm and a new partition standby requirement are proposed in real-time optimal scheduling for the backup problem caused by network congestion and failure outage. In this paper, the reserve capacity requirements of isolated and receiving power systems with multiple partitions are analyzed, and a real-time optimal energy reserve scheduling model with the minimum power and reserve purchase cost as the objective function is established, and the standby requirements of the system are taken into account at the same time. Partition standby requirements N-1 security criteria and other constraints. The model is a very large scale optimization problem, so the dynamic positive set method is introduced into the power system optimal scheduling problem and solved iteratively. Finally, the IEEE 118-bus standard test system and a typical receiver network in China are analyzed. The results show that, The proposed real-time optimal scheduling model and dynamic active set algorithm are used to solve the real-time optimal scheduling scheme of energy reserve and the alternative call scheme after N-1 fault, while meeting the requirements of real-time scheduling calculation time of power system. The rationality of the model and the feasibility of the algorithm are verified. This algorithm can effectively solve the backup supply problem, improve the security of power network operation, and provide a meaningful exploration for real-time optimal dispatching of power system with multi-area.
