Abstract

The invention provides a photovoltaic intelligent power generation system. The photovoltaic intelligent power generation system comprises a photovoltaic battery, an MPPT solar controller, a one-way DC / DC conversion unit, a two-way DC / DC conversion unit, a storage battery pack and an inversion unit. The output end of the photovoltaic cell is electrically connected with the input end of the MPPT solar controller and the input end of the one-way DC / DC conversion unit. The output end of the one-way DC / DC conversion unit and the first end of the two-way DC / DC conversion unit are electrically connected with a direct current bus, and the second end of the two-way DC / DC conversion unit is electrically connected with the storage battery pack; the MPPT solar controller is also electrically connectedwith the storage battery pack; the MPPT solar controller tracks the maximum output power of the photovoltaic cell, and selectively introduces the output voltage of the photovoltaic cell correspondingto the maximum output power into the input end of the one-way DC / DC conversion unit; and the MPPT solar controller also adjusts the output power of the storage battery pack.

Description

technical field

[0001] The invention relates to the technical field of photovoltaic cell grid-connected power generation equipment, in particular to a photovoltaic intelligent power generation system. Background technique

[0002] Environmental pollution has accelerated human research on the use of renewable energy. Among all renewable energy resources, solar energy is the largest, most widely distributed, clean and pollution-free energy. The photovoltaic power generation system is regarded as the most important part of the future smart grid, which can effectively realize the transfer of power energy on the grid side, and realize peak shaving and valley filling of energy through energy storage devices. Solar energy has uncertainty and randomness. This problem has become the most important problem faced by photovoltaic power generation, which makes the output of photovoltaic power generation fluctuate continuously. If the problem of output fluctuation cannot be effectively so...
