This paper presents a discrete frequency control scheme for multiagent system (MAS)-based islanded microgrid (MG) under noisy communication links. The distributed generators (DGs) in a continuous time MG are termed a MAS with a cyberphysical communication network. In order to obtain a cost-effective solution, here a discrete sampled control scheme is utilized for frequency restoration under noisy communication network. Based on primary level droop control, a discrete coefficient approach is implemented to obtain the operating frequency reference for each DG in the MG. Also, a discrete tracking consensus algorithm is implemented to re-synchronize the frequency of the islanded MG to the nominal value. The MATLAB simulation results envisage the efficacy of proposed approach for frequency restoration under various cases such as load perturbation, plug and play, and variation in the noise parameters.

摘要

This paper presents a discrete frequency control scheme for multiagent system (MAS)-based islanded microgrid (MG) under noisy communication links. The distributed generators (DGs) in a continuous time MG are termed a MAS with a cyberphysical communication network. In order to obtain a cost-effective solution, here a discrete sampled control scheme is utilized for frequency restoration under noisy communication network. Based on primary level droop control, a discrete coefficient approach is implemented to obtain the operating frequency reference for each DG in the MG. Also, a discrete tracking consensus algorithm is implemented to re-synchronize the frequency of the islanded MG to the nominal value. The MATLAB simulation results envisage the efficacy of proposed approach for frequency restoration under various cases such as load perturbation, plug and play, and variation in the noise parameters.
