Embodiment Construction

[0036]The photovoltaic solar energy system control method of the present invention applies a photovoltaic solar energy system. Preferably, the photovoltaic solar energy system has a controller, a photovoltaic component, and a DC converter. The controller can output a signal to the DC converter to adjust the pulse modulation signal output by the DC converter. The duty cycle is changed, thereby changing the input voltage loaded to the photovoltaic module, so that the photovoltaic module works at the maximum power point, thereby improving the energy conversion efficiency of the photovoltaic solar system. Preferably, a processor and a memory are provided in the controller, a computer program is stored in the memory, and the processor implements the above photovoltaic solar energy system control method by executing the computer program.

Abstract

The present invention provides a photovoltaic solar energy system, a control method thereof, and a computer-readable storage medium. The method includes acquiring the output power and sampling current of the current sampling period and the previous sampling period, and obtaining the output power and sampling current of the current sampling period and the previous sampling period according to the output of the current sampling period and the previous sampling period. Power and sampling current determine whether the working environment is a multi-power extreme value environment; if it is confirmed that the current working environment is a multi-power extreme value environment, change the duty cycle of the pulse modulation signal by the preset first step length, and calculate each The output power corresponding to the duty cycle is searched for the target duty cycle of the pulse modulation signal corresponding to the maximum output power, and the duty cycle of the pulse modulation signal output by the DC converter is adjusted to the target duty cycle. The present invention also provides a photovoltaic solar energy system and a computer-readable storage medium implementing the above method. The invention can quickly find the duty ratio corresponding to the pulse modulation signal corresponding to the maximum output power, and can reduce the production cost of the photovoltaic solar energy system.

Description

technical field [0001] The present invention relates to the control field of photovoltaic solar energy systems, in particular, to a photovoltaic solar energy system control method, photovoltaic solar energy system and computer-readable storage medium applying the method. Background technique [0002] Photovoltaic solar system can convert solar energy into electrical energy, is an environmentally friendly system that utilizes renewable energy, and has gradually been widely used. The photovoltaic solar system is provided with photovoltaic modules, which include a large number of photovoltaic arrays, and the photovoltaic modules can convert solar energy into direct current. In the current mainstream and commercialized solar photovoltaic solar systems, the energy conversion efficiency of photovoltaic modules is not high, usually around 20%. However, in practical applications, due to the influence of environmental factors, the actual efficiency of photovoltaic solar systems is e...
