Abstract
A power conversion method for an AC direct grid-connected type battery energy storage system is provided. The AC direct grid-connected type battery energy storage system includes at least one energy storage module, each energy storage module includes A, B and C three phase units composed of upper bridge arms and/or lower bridge arms, each bridge arm includes series-connected full-controlled battery modules and an inductor connected in series. High-voltage terminals of all the upper bridge arms of the energy storage module are connected to form a positive DC bus, and low-voltage terminals of all the lower bridge arms of the energy storage module are connected to form a negative DC bus. A low-voltage terminal of the upper bridge arm and a high-voltage terminal of the lower bridge arm of each phase unit are connected to form an AC terminal of the phase unit to connect with an external AC system.
