AB In recent years, Quasi-Z-source cascaded H-bridgemultilevel inverters (qZS-CHBMLIs) have become an interestingsolution for integrating renewable energy into the utility grid. Thepossibility of performing power conversion in a single stage,without an additional DC/DC converter, and a higher voltage gain,are their main advantages over traditional inverters. In addition,individual control of the maximum power point tracking (MPPT)can be achieved for each PV plant. Owing to the intermittent natureof PV power plants, battery energy storage systems (BESS) arecommonly used to smooth out PV power fluctuations. This paperpresents a control system for the active and reactive powerdelivered to the grid according to the system operator referencesand an EMS for an ES-qZS-CHBMLI. The BESS is coordinatedthrough an energy management system (EMS) based on the stateof charge (SOC) The system is evaluated under two differentoperation modes. One of them, where the PV power plants operateaccording to their MPP and the other in which the MPPT faultsand thus, the PV power is decreased. A MATLAB-Simulinksimulation is used to validate the proposed control system for agrid-connected single-phase configuration based on a qZSCHBMLI with three cascade qZSI, each connected to a 4.8 kW PVpower plant and a BESS
