The invention discloses an optimization method for generating capacity of a distributed photovoltaic power station. The method comprises the following steps of optimizing an installation position of aphotovoltaic module array, carrying out real-time optimization on a tilt angle of a photovoltaic steering bracket; carrying out power optimization on photovoltaic modules; and estimating the generating capacity of a photovoltaic power generation system in the next ten years after the photovoltaic modules are optimized and adopting typical meteorological years as meteorological data of predictingthe future generating capacity. The optimization method for the generating capacity of the distributed photovoltaic power station comprises optimization of the installation position of the photovoltaic module array, real-time optimization of the tilt angle of the photovoltaic steering bracket and power optimization of the photovoltaic modules, so that the mismatch phenomenon is not generated between a photovoltaic panel and the photovoltaic modules through cooperative application of three kinds of optimization; meanwhile, each photovoltaic module can output maximum power, so that the generating capacity of the whole distributed photovoltaic power station reaches the optimum value; and the generating capacity of the photovoltaic power generation system in the next ten years after the photovoltaic modules are optimized can be estimated for reference, so that the optimization method has a good application prospect.

Description

technical field [0001] The invention relates to a method for optimizing the power generation of a distributed photovoltaic power station, which belongs to the technical field of photovoltaic power generation. Background technique [0002] With the rapid development of new energy technology, 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. [0003] In order to obtain higher voltage or current output, the photovoltaic power generation system is composed of multiple series or parallel photovoltaic module arrays. The discreteness of photovoltaic module parameters or the difference in solar radiation conditions will cause energy loss in the case of series and parallel connection of photovoltaic modules. Solar photovoltaic panels are placed outdoors, and partial or intermittent shading often occurs, or factors ...
