摘要
In this study, a control approach based on the model predictive control and Smith Predictor is proposed to compensate the effect of communication delay, and keep the stability of the Microgrid (MG) system. A cyber-physical model for the MG system is introduced to define and test the control and communication functions. The MG system consists of two distributed natural gas generators, an energy storage device, a PV system and a wind turbine with constant power. The Smith Predictor based delay compensator approach is applied to the defined MG based system. In addition, the impact of communication delay on MG is simulated and the behavior of the system with and without compensator is compared. The obtained simulation results show that the proposed approach can significantly decrease the impact of communication latency on frequency deviation and the response of the MG system.
