Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation systems, in particular to a multi-level photovoltaic power generation system topology and a control method thereof. Background technique [0002] Photovoltaic power generation system is now the main source of power generation. Its technology is mainly derived from solar energy. By using the sun's irradiation, it converts sunlight into solar energy, and then converts it into electrical energy through the conversion of electrical energy, and supplies it to the national grid and household grid. Now, most of the photovoltaic power generation systems use multi-level, so that the energy is sufficient and the advantages are great. When solar energy is integrated into the grid, it will be connected to the network end, and the connection between the network ends will ensure that the entire network of normal operation. [0003] During the use of the existing photovoltaic power generat...

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a multi-level photovoltaic power generation system topology and its control method, which solves the problem that the overall installation structure of the existing photovoltaic power generation system in the above background technology is relatively single during use. It is not flexible enough, which leads to inconvenient installation. In addition, the network terminal connected to the photovoltaic power generation system has a single topology structure, which has obvious disadvantages and easily causes network paralysis.
