【摘要】：电力系统黑启动预案是电网运行安全的必要保障,但人工进行方案决策的现状难以适应复杂电力系统和多样化的故障后场景。为此,建立电力系统黑启动过程的马尔科夫决策过程模型,提出一种基于状态削减技术和动态规划方法的黑启动方案自动生成算法,其优化目标是以最短的时间将系统恢复至任意预定状态,能够适应不同的故障后场景,支持并行的恢复操作。采用IEEE 14节点系统、新英格兰39节点系统以及鄂东南电网对算法的可行性进行了验证。算例结果表明,该算法能够在较短时间内生成合理的黑启动方案,同时能够在黑启动初期通过发电机组与负荷的协调恢复抑制网架的过电压现象。
[Abstract]:The black-start plan of power system is a necessary guarantee for the security of power network operation, but the present situation of artificial scheme decision is difficult to adapt to complex power system and diversified post-fault scenarios. The Markov decision process model of black-start process in power system is established, and an automatic black-start scheme generation algorithm based on state reduction and dynamic programming is proposed. The optimization goal is to restore the system to any predetermined state in the shortest time, to adapt to different post-fault scenarios, and to support parallel recovery operations. IEEE 14-bus system is adopted. The feasibility of the algorithm is verified by the New England 39-bus system and the southeastern Hubei power grid. The simulation results show that the algorithm can generate a reasonable black-start scheme in a short time. At the same time, the overvoltage phenomenon of grid can be restrained by the coordinated recovery of generator and load in the early stage of black start.
