Abstract: A microgrid self-triggering control method and system for resisting FDI attacks is provided. The method includes the following steps: S1: adopting primary control based on droop control for a microgrid; S2: designing a secondary control strategy of the microgrid, where the secondary control strategy includes frequency recovery and fair distribution of active power; and S3: designing a microgrid distributed self-triggering control method of a hash encryption method after considering the condition that the FDI attacks are injected into a secondary control communication link, so as to resist false malicious data in the microgrid and achieve secondary control. According to the microgrid self-triggering control method and system, a distributed secondary control target of the microgrid is achieved even under the FDI attacks, the injected malicious data can be quickly detected and eliminated, and the distributed secondary control communication network of the microgrid can be protected.
