Abstract

In this paper, a decentralized control framework for reducing power-flow fluctuations at the integration point of DC smart microgrids (SMGs) is proposed. The output powers of non-dispatchable renewable energy resources are unpredictable and vary time to time. In this work, plug-in electric vehicles (PEVs) are employed as distributed energy storage systems (DESSs) in order to minimize the power-flow fluctuations at the integration point. In this regards, the proposed control system increases the charging rates of PEVs in excess power generation and reduces the charging rates in power shortage. The simulations are performed using Matlab/Simulink. According to the simulation results, the proposed method is able to lessen the fluctuations. It also reduces the dependency of SMGs on the main grid and improves the overall power quality in the main power systems as it minimizes the integration point power-flow fluctuations.
