The invention discloses a distributive load dynamic regulation-based microgrid monitoring system, which is characterized by comprising a microgrid controller, a microgrid load controller, a grid-connected point monitor, a distributive power supply monitor and an energy-storage system monitor, wherein the microgrid controller is respectively connected with the microgrid load controller, the grid-connected point monitor, the distributive power supply monitor and the energy-storage system monitor in parallel through a communication network. The invention provides a distributive load dynamic regulation-based microgrid stability control method. According to the invention, due to coordinate control of the microgrid controller and the on-site microgrid load controller, the internal power adjusting speed of a microgrid is increased, the balance between the internal power generation power of the microgrid and the power of a load is maintained, and the operation stability of the microgrid is ensured.
