False data injection attack design and defense method for direct current microgrid

The invention discloses a false data injection attack design and defense method for a direct current microgrid. For a network communication message in the secondary control layer of the direct currentmicrogrid, malicious false data are injected. At the same time, considering the initial state estimation bias and measurement noise existing in the original detection process, a covert data injectionattack method is designed to cause disturbance to current / voltage without affecting the existing attack detection indicators. The covert data injection attack acquired through analysis affects the average voltage value of coupling points in the direct current microgrid. A proportional-integral dynamic average consistency algorithm is used to estimate the average voltage value of the coupling points in the direct current microgrid. The covert data injection attack is detected based on the average voltage deviation of the coupling points. Finally, a proportional-integral compensation mechanismis used to compensate the average voltage deviation of the coupling points. The secondary control input is adjusted. Voltage balance in the direct current microgrid is re-established.
