According to the patent, habitable modules would rotate around a central axis to simulate gravity for crew by producing an outward-pushing centrifugal force.

Two renewable energy sources, wind and solar, are generally studied individually, but their interplay can affect how the grid operates.

Abstract: The virtual synchronous generator (VSG) enhances the inertia of power grid by simulating the dynamic characteristics of a synchronous generator. However, it could induce low-frequency ...
