- AbstractThis paper presents a hybrid PV-battery grid connected system suitable for high power PV powerapplications. High power PV systems have impressive voltage fluctuation with regards to theirmaximum power point voltage. Using DC/DC converters to regulate this voltage is inefficient in highpower systems as it adds an extra power conversion stage. On the other hand switching frequency,voltage stress as inverter limitations and power quality issues should be considered in high powerapplications. Central PV structures because of low efficiency and high cost inverters are not suitablefor high power systems. Maximum power extraction from PV together with active and reactiveinjected power control is another challenge in high power system. Z-source multilevel inverter for PVarrays together with battery energy storage systems is a suitable solution for high power application.This paper proposes a control strategy for this hybrid system. A simulation with PSCAD has beendone to validate the control strategy. Simulation results show how proposed control and topologysatisfies high power requirements for PV grid connected systems.
