[0098] If the vegetation impact coefficient is greater than or equal to the vegetation protection coefficient, the candidate photovoltaic orientation angles of the photovoltaic equipment in the target area are obtained based on the regional wind direction analysis of the target area, specifically:

[0099] Obtain the wind protection angle of the target area according to the regional wind direction of the target area;

[0100] and obtaining a photovoltaic orientation angle set of the photovoltaic device according to the wind protection angle, wherein the photovoltaic orientation angle set includes at least one photovoltaic orientation angle of the photovoltaic device;

[0101] According to the regional wind speed of the target area and the photovoltaic orientation angle where the photovoltaic orientation angle is concentrated, the photovoltaic windproof area corresponding to the photovoltaic orientation angle is obtained;

[0102] The photovoltaic windbreak area is compared with the vegetation protection area. If the vegetation protection area of the target area is within the photovoltaic windbreak area, the photovoltaic orientation angle corresponding to the photovoltaic windbreak area is recorded as the candidate photovoltaic orientation angle.

[0103] In some embodiments, the wind protection angle of the target area is all angles relative to the wind direction of the area; the photovoltaic orientation angle is the angle between the vertical direction of the photovoltaic panel of the photovoltaic device and the horizontal line.

[0104] The comprehensive priority coefficient of the candidate photovoltaic orientation angle is obtained based on the analysis of the regional light direction, the target photovoltaic orientation angle is obtained based on the comprehensive priority coefficient, and the second photovoltaic adjustment instruction of the photovoltaic equipment in the target area is obtained based on the target photovoltaic orientation angle, specifically:

[0105] Obtaining the proportion of the vegetation protection area in the photovoltaic windbreak area corresponding to the photovoltaic orientation angle to be selected, and obtaining the first angle priority coefficient of the photovoltaic orientation angle to be selected based on the proportion of the area;

[0106] Comparing the selected photovoltaic orientation angle with the regional illumination direction of the selected area, obtaining the illumination deviation angle between the selected photovoltaic orientation angle and the regional illumination direction;

[0112] For example, if the first angle priority coefficient of the selected photovoltaic orientation angle is obtained by taking and marking the first angle priority coefficient OX, and the second angle priority coefficient of the selected photovoltaic orientation angle is obtained by taking and marking the second angle priority coefficient TX; then the function The comprehensive priority coefficient ZX of the selected photovoltaic orientation angle is calculated, where a1 and a2 are preset proportional factors. For example, if the first angle priority coefficient of the selected photovoltaic orientation angle is 50, the first angle priority coefficient OX is 50; if the second angle priority coefficient of the selected photovoltaic orientation angle is 10, the second angle priority coefficient TX is 10; if the preset proportional factors a1 and a2 are 0.1 and 100, then the calculation function The calculated comprehensive priority coefficient ZX of the selected photovoltaic orientation angle is 15; the proportional factors a1 and a2 are the influence weights of the first angle priority coefficient and the second angle priority coefficient on the comprehensive priority coefficient, respectively. The calculation function and proportional factors are preset according to the actual impact of the target area during actual application.

[0113] The target photovoltaic orientation angle of the photovoltaic equipment in the target area is obtained based on the comprehensive priority coefficient, specifically:

[0114] The candidate photovoltaic orientation angle with the largest comprehensive priority coefficient in the photovoltaic orientation angle set is recorded as the target photovoltaic orientation angle;

[0115] Among them, if the photovoltaic orientation angle set has only one candidate photovoltaic orientation angle with the largest comprehensive priority coefficient, the candidate photovoltaic orientation angle is recorded as the target photovoltaic orientation angle;

[0116] If there are at least two candidate photovoltaic orientation angles with the same comprehensive priority coefficient and both of them are the largest, then the candidate priority of the candidate photovoltaic orientation angle is generated according to the second angle priority coefficient corresponding to the candidate photovoltaic orientation angle, wherein the candidate priority is negatively correlated with the second angle priority coefficient;

[0117] According to the candidate priorities, the target photovoltaic orientation angle among the candidate photovoltaic orientation angles having the same and maximum comprehensive priority coefficients is obtained.

[0118] In some embodiments, the negative correlation between the priority to be selected and the second angle priority coefficient means that the smaller the second angle priority coefficient is, the higher the priority to be selected corresponding to the photovoltaic orientation angle to be selected is.
