| 摘要: |
| 针对大功率交直流联络线故障将导致受端电网大规模功率缺失，而省域电网内部分机组由省级电网调度，另一部分由区域分中心调度等问题，研究分-省两级电网调度中心实时发电计划协调调整策略。首先建立了省调机组/直调机组有功调整量分配模型和出力跟踪校验模型。针对省调机组/直调机组可能无法完全跟踪分配到的有功调整量的情况，进一步提出了省调机组/直调机组有功协调策略及出力校正模型，形成了一套适用于省域电网大功率缺失场景的省调机组/直调机组实时发电计划协调编制方法。仿真结果表明，与常规实时调度方法相比，该方法有助于快速恢复省域电网大功率缺失后的有功平衡。 |

| Abstract: |
| Failure of high-power AC/DC tie-line will lead to large-scale power loss in the receiving-end power grid, and a part of the provincial units are dispatched by the provincial power grid (P-Units), the other part is dispatched by the regional grid (R-Units). In view of the above problems, the coordinated adjustment strategy of real-time generation plan for regional and provincial dispatching units is studied. Firstly, the models for the allocation of active power adjustment and output tracking between P-Units and R-Units are constructed. For the cases that P-Units or R-Units might not be able to track the allocated active power adjustment, a coordination strategy for active power of P-Units and R-Units is proposed, followed by an output correction model. Together, a set of real-time scheduling methods coordinated P-Units and R-Units which are suitable for provincial power grid under large power loss are formed. Simulation result shows that compared with conventional real-time scheduling method, the proposed method is conducive to fast recovery of provincial grid active power balance after large-scale power loss.
