| 摘要: |
| 采用空间快速负荷分段法建立动态负荷模型，去除空间负荷的时间复杂性。在此基础上，建立结合规划和运行的无功补偿智能协调配置双层模型，上层的规划模型对无功补偿设备的安装位置、类型和容量进行优化配置，下层的运行模型综合考虑不同的负荷场景，优化无功补偿设备的投切方案，使系统达到分级无功平衡。采用双层风驱动算法对模型进行求解。算例结果表明，所提无功补偿方案能够在不同负荷场景下取得良好补偿效果，验证了所提模型和算法的合理性和有效性。 |

| Abstract: |
| The spatial fast load segmentation method is adopted to establish the dynamic load model to remove the time complexity of spatial load, on this basis, a bi-level intelligent harmonious collocation model for reactive power compensation is built with the combination of planning and operation. The upper-level planning model optimizes the collocation of installation location, type and capacity of reactive power compensation equipments, while the lower-level operation model comprehensively considers different load scenarios to optimize the switching schemes of the equipments, which makes power system achieve hierarchical reactive power balance. The bi-level wind-driven algorithm is adopted to solve the model. The case results show that the proposed reactive power compensation scheme can obtain good compensation effect under different load scenarios, verifying the rationality and validity of the proposed model and algorithm. |
