摘要
A cooperative control method and device for a photovoltaic optimizer and a photovoltaic inverter are provided. The cooperative control method and device are applicable to a grid-connected photovoltaic system including N photovoltaic components, N photovoltaic optimizers and one photovoltaic inverter. The N photovoltaic components are respectively connected to input sides of the N photovoltaic optimizers, and output sides of the N photovoltaic optimizers are connected to a DC side of the photovoltaic inverter, N being an integer greater than or equal to 1. The cooperative control method includes determining an operation parameter of the grid-connected photovoltaic system; judging whether the operation parameter is lower than a preset value; and adjusting a voltage of the DC side of the photovoltaic inverter until the operation parameter is not lower than the preset value, in a case that the operation parameter is lower than the preset value.
