Description

technical field [0001] The invention relates to a general detection platform and method for the whole process of grid-connected distributed power supply on the low-voltage user side, and belongs to the technical field of distributed power supply. Background technique [0002] Distributed power generation refers to a small power generation system that is located near the user's location and makes full use of distributed resources for power generation. The power generation methods include distributed natural gas multi-supply, small and medium-sized hydropower, solar energy, wind energy, biomass energy, waste power generation, etc. The generated electricity is not only used by the user itself but also nearby, and the excess electricity is sent to the power generation facilities of the local distribution network, the power generation system or the multi-generation system with power output. Among them, distributed photovoltaics, wind power and distributed natural gas multi-supply...
