Embodiment Construction
[0019] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings and specific embodiments.
[0020] The purpose of the present invention is to provide a microgrid semi-physical test circuit and method based on a feedback load simulation device. For the structure diagram of the specific test circuit, see figure 1 . The input of the regenerative load simulation device is connected to the 0.4KV bus of the microgrid through the connection switch S1, the unit power factor feedback terminal of the regenerative load simulation device is connected to the power distribution system through the connection switch S2, and the energy storage system is connected to the microgrid through the connection switch S3 The 0.4KV busbar is connected, and the microgrid is connected to the grid through the grid-connected point switch DL1 power distribution system. The structure of the regenerative load simulator can be found in ...
