Description

technical field [0001] The invention belongs to the technical field of electric energy management, and in particular relates to a low-voltage distributed power management system. Background technique [0002] As more and more distributed photovoltaics are connected to the low-voltage distribution network, the low-voltage distribution network has gradually changed from a traditional passive network to a multi-source network. Distributed photovoltaic power generation specifically refers to photovoltaic power generation facilities that are built near the user's site, and whose operation mode is characterized by self-consumption on the user side, surplus electricity connected to the grid, and balanced adjustment in the power distribution system. Distributed photovoltaic power generation follows the principles of adapting measures to local conditions, clean and efficient, decentralized layout, and nearby utilization, making full use of local solar energy resources to replace and ...
