description The invention discloses a two-layer three-level coordination control system and method for improving the power quality of a medium-low voltage power distribution network. According to the difference of power quality problems of different nodes, the medium-low voltage power distribution network is divided into a first layer and a second layer. The first layer is a low-voltage system and comprises alow-voltage distribution head, a low-voltage line and a terminal load. The second layer is a medium-voltage system and comprises a transformer substation, a medium-voltage line and a low-voltage transformer area transformer. The two-layer three-level coordination system comprises three governance units in the first layer, three governance units in the second layer and a multi-level coordination controller, and the multi-level coordination controller is in separate communication connection with the three governance units in the first layer and the three governance units in the second layer through communication module
