Abstract

The invention discloses an intelligent component optimizer for a solar photovoltaic cell panel and a control method thereof. A controller for the component optimizer in a component optimization system uses a high-performance high-speed DSP (digital signal processor) as a core, and a high-frequency direct-current switching power supply technology is introduced in a distributed photovoltaic power generation system, direct-current conversion topology for voltage increase or voltage reduction can be selected according to a direct-current conversion adjustment margin, and the working mode of the component optimizer can be selected by a control method of observing a pre-stage input voltage, a pre-stage input current, a post-stage output voltage and a post-stage output current in real time, so that the components of the photovoltaic cell panel cannot generate a mismatching phenomenon in the case of any irradiance; simultaneously, each component can have the maximum power output, thus greatly gaining the electric quantity of a photovoltaic cell array, which is lost due to non-uniform irradiance, so that the power generation utilization rate of the whole photovoltaic cell array is optimal. The component optimizer and the control method have good application prospect.

Description

technical field

[0001] The invention relates to a component optimizer and a control method for an intelligent solar photovoltaic battery panel used to output the maximum power of a photovoltaic battery panel under different incident irradiance conditions, and belongs to the technical field of new energy utilization. Background technique

[0002] As the energy crisis is approaching, new energy has become one of the main energy sources in the world in the future. In recent years, renewable clean energy power generation technologies represented by solar energy have developed rapidly around the world, and photovoltaic power generation systems generally use the same performance Photovoltaic panels are connected in series and parallel to form a photovoltaic array. The principles of photovoltaic panels not being shaded as much as possible should be followed in system design, so that solar energy can be used to the maximum extent. With the proposal and implementation of smart grids, ...
