Microgrid real-time control system and control method thereof

Abstract

The invention provides a microgrid real-time control system and a control method thereof. The microgrid real-time control system comprises an access end used for being connected with an external main power grid, wherein the access end is in signal connection with a control module used for microgrid dispatching control, and the control module is in signal connection with a line management module, a load statistics module and a line analysis module. The control method comprises the steps that: firstly, a micro-grid is connected to a main power grid through the access end, then the control module controls the line management module to complete operation management of each power grid, the line analysis module transmits line information obtained through analysis to the control module, and the load statistics module performs load statistics on the load statistics information of each power grid; and secondly, the optimization module performs optimization distribution in combination with the line operation load information in the load statistics module and the preset data in the prediction module, and transmits an optimization distribution scheme to the control module, and the control module distributes the optimization distribution scheme to each power grid by using the line management module, thereby completing real-time optimization control of each power utilization grid in the micro-grid.

AI Technical Summary

Problems solved by technology

[0004] However, in the existing microgrid operation control, the load in each power consumption unit connected to the microgrid cannot be reasonably distributed. Even distribution will affect the load change at the access end of the microgrid, increase additional load consumption, and cause microgrid. Excessive air consumption inside the power grid occurs, which affects the rationalization of micro-grid control
