There are two control structures for the islanded operation of microgrids: peer-to-peer control and master–slave control.
The microgrid can run not only in the grid-connected mode but in the islanded model [ 5 - 8 ]. Intermittency and randomness characteristics of distributed energy resource and the removal or input of a large number of user loads in the islanded model make the microgrid dynamic response with a wide range.
Based on the basic structure, a two-layer control structure is proposed in [ 21 ], which can maintain voltage stability of the islanded microgrid and also compensate the unbalance active power and reactive power in real time, however, the dynamic characteristic of the voltage control strategy is not improved.
The improved V/f control strategy is composed of two parts, feedforward compensation and robust feedback control. Robust control theory is a powerful tool for processing parameters variation, non-linear loads and other disturbances. The feedforward compensation can effectively reduce the steady-state error of the system.
Static feasibility The proposed microgrid control framework has two main functionalities: 1) regulate the output of GFM inverters through load re-sharing; 2) improve V-f deviation by reallocating generation
