Abstract

The invention discloses a method and device for controlling a micro grid system. The method for controlling the micro grid system comprises the following steps: acquiring the communication state of the micro grid system between a main controller and a subordinate controller; determining a control manner of the micro grid system under the current communication state according to the communication state between the main controller and the subordinate controller; controlling the micro grid system to supply power according to the control manner of the micro grid system. Through the method and the device, the controlling stability of the micro grid system can be improved.

Description

technical field [0001] The present invention relates to the field of power grids, in particular to a control method and device for a micro-grid system. Background technique [0002] The microgrid system is a highly independent decentralized power network, which includes primary equipment such as power supply, load, and energy storage, as well as secondary equipment such as microgrid controllers and protection devices. The development of micro-grid technology helps to use renewable energy more effectively, while enhancing the reliability of power supply of traditional power grids. With the increase of the capacity and number of intermittent power sources in the microgrid, the microgrid is highly decentralized. In addition, in independent islands, mountainous areas, and remote rural areas, the power generation capacity of the main grid is relatively small, and the micro-grids connected in this case are also highly decentralized. [0003] The traditional micro-grid control sy...
