6 FAQs about [Research status of microgrid equivalent modeling]

How to build a dynamic equivalent model of microgrid?

To build a dynamic equivalent model of microgrid,the instantaneous value of current and voltage at the port of microgrid are recorded. To simplified the data structure, these physical quantity are transformed into α β -frame, which may reduce the dimension of data. Time sequence of voltage ( V α, β) is selected as the input.
