A detection unit collects the power generation amount of a photovoltaic power generation system in a photovoltaic bus and model influence parameters required for load prediction provided by a network terminal to establish a photovoltaic power generation module load prediction model and real-time load prediction; and the power generation amount is obtained through load prediction to determine wireless charging time to achieve intelligent charge of the photovoltaic bus. Through collection of the power generation amount of the photovoltaic power generation system in the photovoltaic bus and model influence parameters required for load prediction, establishing of the photovoltaic power generation module load prediction model and real-time load prediction is determined by adopting the regression analysis method and the least square method; and the power generation amount is obtained through load prediction to determine wireless charging time to achieve the intelligent charging of the photovoltaicbus. the utilization rate of the photovoltaic generation is improved, and the electric power cost of the photovoltaic bus is reduced.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation control, and in particular relates to a photovoltaic bus intelligent charging management and control method and system. Background technique [0002] At present, the closest existing technology: Photovoltaic (Photovoltaic): It is the abbreviation of solar photovoltaic power generation system (Solarpower system), which is a kind of photovoltaic effect that uses solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. The new power generation system has two modes of independent operation and grid-connected operation. At the same time, the classification of solar photovoltaic power generation systems, one is centralized, such as large-scale Northwest ground photovoltaic power generation systems; the other is distributed (with >6MW as the boundary), such as industrial and commercial enterprise factory roof photovoltaic power generat...
