energy storage system (ESS). In single-phase systems, the DC/AC inverter has a second-order harmonic at twice the grid … component because of the ripple of the DC-link voltage. The second-order harmonic adversely affects the battery lifetime. The … proposed algorithm has an advantage of reducing the second-order harmonic of the output current in the variable frequency …

This paper proposes a second-order harmonic reduction technique using a proportional-resonant (PR) controller for a … the operation of the maximum power point tracking (MPPT) technique.
