Problems solved by technology
[0003] However, in the current mainstream micro-grid platform, due to the centralized control strategy of the micro-grid energy management system, the real-time algorithm layer of the distributed power supply is not open, only the communication protocol is open. In general, the main power generation is adopted in the system, that is, the energy storage inverter is the center It is difficult to verify the distributed real-time control strategy with more energy storage and less communication. Based on this, the present invention designs a microgrid secondary control test platform based on a rapid prototype controller to solve the above problems

The invention discloses a microgrid secondary control test platform based on a rapid prototype controller in the field of new energy technology, including a first simulation source, a second simulation source, a third simulation source and a fourth simulation source, the first One end of the analog source is connected to a switch K18, and one end of the switch K18 is connected to a 380V AC power distribution cabinet; one end of the 380V AC power distribution cabinet is connected to a grid simulator, and one end of the grid simulator is connected to a switch K17. The present invention uses four sets of bidirectional AC / DC converters as analog energy storage micro-grid sub-sites, and four sets of DC / AC converters as distributed power drivers for analog sub-sites, reducing the cost of using the platform, and the circuit structure is symmetrical , the user can not only perform distributed real-time strategy control, but also realize the power working scenarios of energy storage battery simulation, photovoltaic system simulation and wind power system simulation through the control program of the external AC / DC converter.
Description
Technical field [0001] The present invention relates to the field of new energy technologies, in particular a secondary control test platform based on a fast-prototype controller. Background technique [0002] In recent years, my country's new energy (wind, light, storage) grid is greatly improved, and the penetration rate of new energy in some areas has increased significantly. In September 2020, my country further explicitly proposed the 2060 dual carbon target, to 2030, carbon Damong, in 2060, carbon neutralization, fully reflecting my country's attention to the global environment, human common home, my country's attention, emission reduction, and efforts of emission reduction, in this grand historical goal, a new round of new Energy construction will further develop rapidly. At present, the coordination control of the microgrid is mainly two strategies, one is a centralized control strategy. This is the main successful experience under traditional large power grids. By deploy...
