Abstract

The embodiment of the invention provides a photovoltaic module string connection method and device, equipment, and a storage medium, and relates to the technical field of photovoltaic power generation. The method comprises the following steps of: acquiring position information of n photovoltaic modules to be connected; dividing the n photovoltaic modules into m partitions according to the positioninformation of the n photovoltaic modules; for the ith partition in the m partitions, generating k candidate connection schemes, wherein the ith partition comprises ni photovoltaic modules, and eachcandidate connection scheme in the k candidate connection schemes is at least one photovoltaic module string obtained by taking one photovoltaic module in the ni photovoltaic modules as a starting point and simulating connection of the ni photovoltaic modules according to a preset connection scheme; and selecting a target connection scheme from the k candidate connection schemes according to the predicted cable usage amounts corresponding to the k candidate connection schemes. According to the technical scheme provided by the embodiment of the invention, the string connection efficiency of thephotovoltaic module can be improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of photovoltaic power generation, and in particular to a method, device, equipment and storage medium for connecting photovoltaic modules in series. Background technique [0002] The basic power generation unit of a photovoltaic power station is a photovoltaic module. During the construction of a photovoltaic power station, the photovoltaic modules need to be connected in series. [0003] In the related technology, after the connection of each photovoltaic string is completed, the positive and negative poles of the photovoltaic string are left at both ends. In order to connect the photovoltaic string to the combiner box, it is necessary to use cables to connect the One pole is connected to the vicinity of the other pole, and then the photovoltaic string is connected to the combiner box or inverter through the same cable channel. Therefore, the closer the positive and negative pol...
