Abstract

The invention is suitable for the technical field of power system control, and provides a microgrid control method, computer equipment, a storage medium and a microgrid system. The microgrid system comprises a microgrid end and a large grid end, wherein the microgrid end and the large grid end are in communication connection through a network; the microgrid end is used for obtaining a micro-grid state model and sending first trigger state information to the large grid end, wherein the first trigger state information is state information corresponding to the moment when the micro-grid end triggers a first event model; and the large power grid end is used for receiving the first trigger state information, predicting the first non-trigger state information through the prediction model, and controlling the states of the current value and the voltage value of the microgrid end according to the first trigger state information and the first non-trigger state information. According to the scheme, by setting the prediction model, the large grid end can obtain the state information of the micro power grid end at the moment when the first event model is not triggered, so that the large grid end can control the micro-grid according to the state information of the micro-grid end at all sampling moments, and the control accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of power system control, and in particular relates to a micro-grid control method, computer equipment, storage media and a micro-grid system. Background technique [0002] Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. The microgrid integrates the advantages of distributed power generation and provides a platform for the effective use of new energy. As a new energy source, when it operates in an isolated island, it can obtain energy independence, which greatly reduces the dependence on the power grid. The power load of the microgrid end is large, and when the power is not enough, the large grid can be controlled to transmit to the microgrid. Information exchange is required between the grid end and the large grid end, so that the large grid end can k...
