| 摘要: |
| 提出了基于区域电网间断面功率约束的互联电网静态电压稳定预防控制模型及其算法。该预防控制模型以控制代价最小为目标，约束条件包含了正常运行状态下的可行性约束、预想故障状态下的静态电压稳定裕度约束，以及各个运行状态下区域电网间传输断面的功率约束。该模型不但可以保证互联电网在各种运行状态下的静态电压稳定性，且能满足区域断面之间的交易功率约束。针对互联电网分层分区管理的特点，进一步建立了互联电网静态电压稳定预防控制的分解协调优化模型，并采用分解协调内点法求解。仿真结果表明了所提互联电网静态电压稳定预防控制模型及其算法的正确性及有效性。 |

| Abstract: |
| Based on the interface power constraints of regional power grid，a preventive control model of static voltage stability and its algorithm are proposed for the interconnected power grid，which takes the minimum control cost as its objective and includes following constraints：the feasibility constraints under normal operation，the static voltage stability margin constraints under critical contingency and the interface power constraints of regional power grid under different operational states. It guarantees the static voltage stability of interconnected power grid under different operational states，and satisfies the trade power constraints of interfaces. According to the hierarchical and regional management of the interconnected power grid，an optimal decomposition-coordination model of static voltage preventive control is built and solved by the decomposition-coordination interior point method. Simulative results verify the correctness and effectiveness of the proposed model and algorithm. |
