Abstract EN
System security is essential for the operation of the island microgrid.
However, the system security is generally threatened due to the presence of physical uncertainties and cyber attacks.
In this article, a novel sliding mode load control strategy is proposed for the microgrid to mitigate cyber attacks and physical uncertainties.
Firstly, a high-order disturbance observer (HODO) is designed to estimate the unmeasurable factors in the microgrid.
Secondly, a HODO-based sliding mode control (SMC) strategy is proposed where the estimated value observed by the HODO is applied to the sliding mode surface and control law.
It can better guarantee the security of the isolated microgrid.
Then, the stability of the HODO-based SMC is demonstrated by Lyapunov stability theory.
Finally, simulation results show that the proposed control strategy has excellent control performance.
