Photovoltaic power supply control method

The invention provides a photovoltaic power supply control method, which is used for controlling a photovoltaic power supply control system and comprises the step of preferentially using a photovoltaic power generation module to supply power according to the power utilization demand of an electric arc furnace module. The energy of the photovoltaic power generation module can be locally consumed, and the utilization rate of solar photovoltaic power generation is improved. A power supply module can be connected to guarantee normal operation of the electric arc furnace module under the condition that the generating capacity of the photovoltaic power generation module is insufficient. The local consumption scale of the photovoltaic power generation energy is effectively improved, and the power utilization cost of a production enterprise can be greatly reduced. 本发明提供一种光伏供电控制方法，所述光伏供电控制方法对光伏供电控制系统进行控制，包括：根据所述电弧炉模块的用电需求，优先使用所述光伏发电模块进行供电。可就地消纳光伏发电模块的能源，提升太阳能光伏发电的利用率，并可在光伏发电模块发电量不足的情况下接入供电模块保证电弧炉模块的正常作业，有效提高了光伏发电能源就地消
