【摘要】：实际大规模输电网架恢复时间与空间跨度大,涉及操作众多,需要各级调度共同参与,因此提出一种网架恢复的分层协同优化方法。引入"受电点"的概念,将输电网架拆分,构建基于受电点指标约定的恢复协作机制,继而建立网架恢复的分层协同优化模型。该模型将主网架重构完成度与各地区新增发电量作为优化目标,采用分层次独立优化与受电点指标值整体寻优相结合的方法,可有效降低问题求解规模,并能够兼顾求解全局性与各层级的恢复偏好。通过受电点指标约定,明确任务分工与各地区的操作边界,能够实现有功、无功的协调控制与分层分区独立并行恢复,可显著提高恢复效率。山东电网实际算例验证了所提方法的有效性和实用性。
[Abstract]:The restoration time and space span of large-scale transmission network is large, which involves a lot of operations and requires the participation of all levels of dispatching. Therefore, a hierarchical cooperative optimization method for grid restoration is proposed. The concept of "receiving point" is introduced to split the transmission grid frame. The cooperative recovery mechanism based on the target of receiving electricity is constructed, and then the hierarchical cooperative optimization model of grid recovery is established, which takes the completion degree of main grid reconfiguration and the new power generation in each region as the optimization objectives. By combining the hierarchical independent optimization with the overall optimization of the index value of the receiving point, the scale of solving the problem can be effectively reduced, and the global solution and the recovery preference of each level can be taken into account. By clarifying the division of tasks and the operation boundary of each region, the coordination control of active and reactive power and the independent and parallel restoration of hierarchical and partitioned work can be realized, and the recovery efficiency can be improved significantly. The effectiveness and practicability of the proposed method are verified by an actual example of Shandong Power Grid.
