摘要
当电网大停电之后,运行人员快速高效地把电力系统恢复到正常运行状态,不仅可以降低发电侧的设备损害程度,还可提高用电侧负荷的恢复速度。重点分析了没有自启动能力的机组时间限制、系统总容量限制、启动功率限制、机组恢复优先权限制等条件,通过混合二元整数规划算法得到系统恢复过程中机组启动次序的策略。结论表明:在给定恢复时间内,采用这种策略能在保证机组的安全运行和系统的最大发电容量的前提下,得到系统机组启动的最优次序,可直接减少后期系统重构和负荷恢复的时间。
When the power grid blackout, making the power system restore normal operation quickly and efficiently can not only reduce the equipment damage of the power generation side, but also improve the load restoration speed of the power side. This paper focuses on the ability of the units which have not self-starting time limit, total system capacity constraints, start power limit, and the constraints of unit restoration priority, and gets the unit start sequence strategy for system restoration process through the mixed binary integer programming algorithm. It is concluded that: in a given recovery time, this strategy can get the optimal order of the system unit startup under the premise of ensuring the safe operation of the unit and the maximum generation capacity of system, and can reduce the post-reconstruction and load restoration time directly.
