For the energy storage dc/dc parallel supply system with low-frequency pulsed load, an unbalanced dynamic power distribution problem will occur due to the inconsistent dc inertia of each converter, even resulting in a severe continuous low-frequency power oscillation. For this, a dynamic power balancing control method is proposed to reshape their dc inertia
