Problems solved by technology
However, due to the large scale of the distribution network, if the data of each load point is to be collected, a large number of collection terminals and communication networks need to be built, and the investment is huge. In the actual distribution network, the load information of many nodes cannot be obtained.

The invention discloses an intelligent power distribution network reconstructing method based on characteristic load injection. According to the method, reconstruction of a power distribution network is realized under the condition of not acquiring the specific load data of the power distribution network, and the characteristic load curve of a load injection node does not change under the condition of not changing the load construction. The method is more flexible, and has high practicability. In the reconstructing process of the power distribution network, the network loss is taken as an index to comprehensively select a running way of which the network loss is minimal. The loss can be lowered effectively, and the running economical efficiency of the power distribution network is increased. Meanwhile, through the method, the utilization ratio of power distribution equipment can be increased, the action times of the equipment are reduced, the service life of the equipment is prolonged, and the economic benefit of the power distribution network is increased feasibly.
Description
technical field [0001] The invention relates to a method for reconfiguring an intelligent distribution network based on characteristic load injection, and belongs to the field of intelligent grids. Background technique [0002] Intelligent distribution network reconfiguration is to find an optimal power supply network structure for the load of the distribution network. Under this network structure, the loss, operating voltage and load balance of the distribution network are better than other schemes. In the case of network power supply, by changing the combined state of the section switch and tie switch to ensure that the distribution network operates in a safe, high-quality, and economical state for a period of time. [0003] The network reconfiguration of the distribution network must obtain the indicators that need to be optimized through power flow calculations, so it is necessary to be able to obtain the load information of each node in the network. However, due to the...
