technical field [0001] The invention relates to the field of power electronic equipment control, in particular to a flexible multi-state switch control method for promoting the consumption of distributed power sources. Background technique [0002] With the highlight of the global energy crisis, distributed power as an important form of utilizing new energy has been paid more and more attention. Distributed renewable energy generation is connected to the distribution network, which can realize energy consumption on the spot and reduce transmission loss. However, due to the unreasonable structure of the traditional distribution network and the limited means of regulation and control, the uneven distribution of the power flow brought about by the access of distributed power sources, and the problems of system voltage changes exceeding the limit cannot be well suppressed, thus limiting the distribution network. The ability to absorb distributed power. It cannot meet the curre...
