Web9 dec. 2024 · The Virtual Synchronous Generator (VSG) adds rotational inertia and damping co-efficient to traditional inverter control, which enhances the anti-interference ability of the microgrid (MG). However, the adding segment negatively impacts the response speed of the system. Hence, a coordinated adaptive control strategy of rotational inertia … WebUnder, Over and Critical Damping OCW 18.03SC or x(t) = e−bt/2m(c 1 cos(ω dt)+ c 2 sin(ω dt)) = Ae−bt/2m cos(ω dt − φ). (3) Let’s analyze this physically. When b = 0 the response is a sinusoid. Damping is a frictional force, so it generates heat and dissipates energy. When the damping constant b is small we would expect the system to ...
