Intelligent harmonious collocation for reactive power compensation of distribution network combining planning and operation

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.
