Decentralized Predictive Control Of Distributed Generator And Energy Storage System In An Islanded Microgrids

This paper presents a decentralized power flow control scheme for an islanded microgrid which comprises multiple PV/Battery hybrid sources. Conventional droop control with Model Predictive Control (MPC) is employed to track maximum power of Photovoltaic (PV) module, regulate voltage at DC bus and manage the power among hybrid sources. Moreover, by applying optimum switching sequence to battery converter can control the State-of-Charge (SoC) of batteries. In the proposed control method higher SoC of battery delivers more power than that with lower SoC. Finally, Load power sharing between distributed generator with energy storage hybrid systems is presented in order to validate the proposed control strategy.
