Title:
PHYSICALLY SYNCHRONIZED PHOTOVOLTAIC-STORAGE HYBRID POWER GENERATION SYSTEM AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/108890
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of new energy, and provides a physically synchronized photovoltaic-storage hybrid power generation system and an operation method thereof. The system comprises: a photovoltaic module comprising a photovoltaic unit and a first converter unit and a second converter unit each electrically connected to the photovoltaic unit; an energy storage module comprising an energy storage unit and a third converter unit, two ends of the energy storage unit being electrically connected to the first converter unit and the third converter unit, respectively; a grid-connected module, one end of the grid-connected module being electrically connected to the second converter unit and the third converter unit, and another end of the grid-connected module being connected to a target large power grid; and a control module, which is separately electrically connected to the photovoltaic module, the energy storage module and the grid-connected module, and is used to set a control parameter of the photovoltaic-storage hybrid power generation system, adjust an operating state of the energy storage unit by means of evaluating a logic relationship between the power of the photovoltaic unit and the power of the target large power grid, and carry out synchronous grid connection of the photovoltaic-storage hybrid power generation system.
