Grid-connected operation control method for energy storage converter

The invention discloses a grid-connected operation control method for an energy storage converter. The grid-connected operation control method comprises a grid connection point active power control mode, a grid connection point reactive power compensation mode, a grid connection point harmonic current compensation mode and the like. Under the grid connection point active power control mode, the energy storage converter controls the active power according to an upper dispatch instruction, so as to control the active power of a grid connection point. Under the grid connection point reactive power compensation mode, the energy storage converter controls the reactive power according to the upper dispatch instruction, so as to compensate the reactive power of the grid connection point. Under the grid connection point harmonic current compensation mode, the energy storage converter controls the harmonic current, so as to compensate the harmonic current grid connection point. 种储能变流器并网运行控制方法，包括并网点有功功率控制模式、并网点无功功率补偿模式
