and S3, comparing the current power generation efficiency with the maximum power generation efficiency, and correspondingly adjusting the wind power generation module and/or the photovoltaic power generation module when the difference value between the current power generation efficiency and the maximum power generation efficiency reaches a threshold value.
In the embodiment of the application, in order to improve the overall efficiency of the wind and photovoltaic power generation system, the wind and photovoltaic power generation system comprises a wind power generation module and a photovoltaic power generation module, and correspondingly, the wind power generation module corresponds to an adjusting device of the wind power generation module and can adjust the position of the wind power generation module so as to adapt to different wind directions; the photovoltaic power generation module corresponds to the adjusting device of the photovoltaic power generation module and can adjust the position of the photovoltaic power generation module, so that the solar photovoltaic power generation module can adapt to different sunshine directions. When the method is implemented specifically, if the adjusting device is adjusted along the wind direction or the sunshine direction in real time, the adjusting device can be caused to operate frequently, and when the difference of the generating efficiency is not large, the adjusting device needs to be driven, energy consumption is needed, and the whole efficiency is not obviously improved. The specific threshold value can refer to the power consumption of the adjusting device, so that the power consumption is guaranteed, and meanwhile, when the power generation efficiency of the whole system is remarkably improved, the wind power generation module needs to be adjusted to improve the overall power generation efficiency.
Similarly, the maximum photovoltaic power generation efficiency at the current time is obtained based on the second preset time, after the maximum photovoltaic power generation efficiency is obtained, the maximum photovoltaic power generation efficiency is compared with the current photovoltaic power generation efficiency, if the maximum photovoltaic power generation efficiency is larger than the current photovoltaic power generation efficiency, and the difference value reaches the second threshold value, the current photovoltaic power generation efficiency at the moment is lower, and a power generation scheme with higher photovoltaic power generation efficiency exists, so that the photovoltaic power generation efficiency is changed by adjusting the photovoltaic power generation modules, and the power generation efficiency of the whole system is improved.

and adjusting the position of the wind power generation module based on the wind direction of the maximum wind power generation efficiency, so that the wind power generation module is arranged corresponding to the wind direction of the maximum wind power generation efficiency.
In the embodiment of the application, when the current wind power generation efficiency is lower than the current maximum wind power generation efficiency and reaches the threshold value, the adjustment of the wind power generation module is needed, so that the wind power generation efficiency is improved, therefore, the wind direction of the maximum wind power generation efficiency needs to be acquired, when the wind power generation device is specifically implemented, the wind power generation efficiency of different orientations of the small wind power generation device can be acquired by arranging a small wind power generation device, the position information of the small wind power generation device is acquired at the time of the maximum wind power generation efficiency, the whole wind power generation module is correspondingly adjusted, and the maximum wind power generation efficiency is reached after the position of the wind power generation module is adjusted.

This application is when concrete implementation, if adjust along with wind direction or sunshine direction in real time, can lead to adjusting device frequently to function, and when the generating efficiency difference is not big, because adjusting device itself also needs the drive, need the energy consumption, it is not obvious to lead to holistic efficiency promotion, therefore, based on first predetermined time, acquire the maximum wind power generation efficiency of current time, after acquiring maximum wind power generation efficiency, can contrast with current wind power generation efficiency, if maximum wind power generation efficiency will be greater than current wind power generation efficiency, and the difference reaches first threshold value, it is lower to explain current wind power generation efficiency this moment, and there is the power generation scheme of higher wind power generation efficiency, consequently, through adjusting wind power generation module, change wind power generation efficiency, thereby improve entire system's generating efficiency. The specific threshold value can refer to the power consumption of the adjusting device, so that the power consumption is guaranteed, and meanwhile, when the power generation efficiency of the whole system is remarkably improved, the wind power generation module needs to be adjusted to improve the whole power generation efficiency.
