Description

technical field [0001] The invention relates to the technical field of micro-grids, in particular to an RT-LAB-based micro-grid simulation test system. Background technique [0002] Microgrid technology is based on local resource conditions, rationally selects and comprehensively utilizes a variety of 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 of efficient utilization of renewable energy in the future. Microgrid technology can increase the proportion of distributed renewable energy access to the power system and the reliability of power supply, and provide power supply for power-scarce areas such as islands and rural areas, which has important economic and environmental benefits. At present, countries all over the world are vigorously promoting and developing micro-...
