Description

Technical field [0001] The invention relates to the technical field of micro-grids, in particular to a micro-grid simulation test system based on RT-LAB. Background technique [0002] Microgrid technology is based on local resource conditions, rationally selecting and comprehensively utilizing multiple renewable energy sources (solar energy, wind energy, ocean energy, biomass energy, backup diesel engines, etc.) to form a distributed renewable energy power supply system to achieve independent operation or grid connection Operation is the main direction for the efficient use of renewable energy in the future. Microgrid technology can increase the proportion of distributed renewable energy connected to the power system and the reliability of power supply, and provide power supply for islands and rural areas where power is lacking, which has important economic and environmental benefits. At present, countries around the world are vigorously promoting the development of microgrid te...
