Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a simulation method and system for a direct current distribution network. Background technique [0002] The distribution network refers to the network structure from the transmission network to the user, which is composed of distribution lines, distribution transformers and auxiliary facilities, and plays the role of distributing electric energy in the power network. The traditional distribution network adopts the AC power distribution method, and uses the electromagnetic induction principle of the transformer to change the voltage. Modern power grids are facing challenges such as a large number of distributed power generation and grid connection. The traditional AC distribution network method must go through multi-level conversion links for both distributed power generation and modern DC power consumption equipment, which will inevitably increase the complexity of the syst...
