Abstract
With the improvement of performance requirements for power grid, it is of great significance to realize the collaborative planning of primary and secondary equipment in distribution network. The collaborative planning takes into account the cooperation of primary and secondary equipment, which makes the equipment play a more efficient role and improves the accuracy of index calculation. In this paper, a collaborative planning method for primary and secondary equipment considering extreme weather is proposed. First, considering extreme weather, hierarchical clustering and scenario reduction are used to generate typical fault scenario sets. Then, the outage time calculation model under the first and second cooperation is established. On this basis, a collaborative configuration of primary and secondary equipment is established. The improved firefly algorithm is used to solve the model. The validity of the model is verified on an IEEE 33 bus system. The results show that collaborative planning can give full play to the role of equipment, reduce outage losses, and improve system reliability.
