The invention discloses a DC micro-grid multi-energy storage voltage adaptive dynamic control method, a storage medium and equipment, and the method comprises the steps: an energy storage converter employing a virtual synchronous generator control strategy designs an adaptive control strategy of a virtual inertia and a damping coefficient according to the dynamic condition of a DC bus voltage when the DC micro-grid generates power oscillation; voltage outer loop PI control is carried out, and current inner loop PI control is carried out in combination with a current disturbance value of an energy storage converter actually input to the DC micro-grid under a virtual synchronous generator control strategy, so that adaptive power compensation control is realized; the energy storage converter adopting the constant power control strategy is connected to the direct current micro-grid under the condition of setting the fixed output power, PI control is carried out by combining the current disturbance value actually
