<p>With the rapid development of renewable energy, power system characteristics have been significantly changed by including numerous power electronic inverters, which has led to a series of problems, such as wideband oscillations, inertia deficiency, weakened grid strength, etc. To solve these problems, the authors proposed a dual winding induction machine (DWIM)-based generating system. The DWIM is utilized instead of the conventional inverter as an interface for renewable energy integration. One set of the DWIM stator windings is connected to the grid directly, while the other is connected to an inverter. The DC side of the inverter is powered by renewable energy resources or energy storage units. With the help of the proposed system, the power system is expected to regain the characteristics of the synchronous generator-dominated system such as strong stability, rotational inertia, and large short-circuit currents. In order to make the proposed system applicable, this paper focuses on the control methods. By analyzing the double-<i>dq</i> mathematical model and the vector space decomposition (VSD) mathematical model of DWIM, as well as the relationship between them, two equivalent control methods are proposed. These control methods enable independent control of the active and the reactive power exchanged with the grid. Some experiment results verified the effectiveness of these control methods and then the feasibility of the DWIM-based generating system.</p>
