Summary:The access of microgrid will directly affect the voltage quality and operation level of medium-voltage distribution network, resulting in the change of power flow direction and the formation of multi-source network. Based on reliability and economy, this paper quantitatively evaluates the influence of microgrid on typical power supply modes of medium-voltage distribution network, determines the optimal access location and capacity, and proposes a construction mode of medium-voltage distribution network suitable for microgrid access. Through the study, it is concluded that the microgrid connected to the radial overhead lines can significantly improve the reliability of power supply, and the farther the access point is, the higher the reliability is. At the same time, it is necessary to improve the economy of microgrid access.
