Microgrid secondary control test platform based on rapid prototype controller

Abstract

The invention discloses a microgrid secondary control test platform based on a rapid prototype controller in the technical field of new energy. The microgrid secondary control test platform comprises a first simulation source, a second simulation source, a third simulation source and a fourth simulation source, one end of the first simulation source is connected with a switch K18, and one end of the switch K18 is connected with a 380V AC power distribution cabinet; and one end of the 380V AC power distribution cabinet is connected with a power grid simulator, and one end of the power grid simulator is connected with a switch K17. According to the invention, four groups of bidirectional AC / DC converters are used as analog energy storage micro-grid substations, and four groups of DC / AC converters are used as distributed power supply drivers of the analog substations, so that the use cost of the platform is reduced, the circuit structure is symmetrical, and a user can carry out distributed real-time strategy control and also can realize power supply working scenes of energy storage battery simulation, photovoltaic system simulation and wind power generation system simulation through a control program of an external AC / DC converter.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a micro-grid secondary control test platform based on a rapid prototype controller. Background technique [0002] In recent years, the proportion of my country's new energy (wind, solar, storage) grid connection has increased significantly, and the penetration rate of new energy in some areas has increased significantly. In September 2020, my country further clearly proposed the dual carbon goal of 2060. By 2030, the carbon Dafeng, the realization of carbon neutrality in 2060 fully reflects our country's emphasis on the earth's environment and the common home of mankind, our country's concern about the global climate, and our sincerity and efforts to reduce emissions. Under this grand historical goal, a new round of new Energy construction will likely further develop rapidly. At present, the coordinated control of wind, light and storage in the microgrid mainly adopts two strat...

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
