The invention relates to the field of energy power, in particular to a power system switching method and device, equipment and a storage medium. The method comprises the steps that a power system switching instruction is obtained; a power change rate and a switching-out point power value are obtained according to a driving state parameter at the moment of acquiring the switching instruction; the output power of a switching-out system at the power change rate is decreased, and the output power of a switching-in system at the power change rate is increased; and when the value of the output powerof the switching-out system is reduced to a switching-out point power value, operating of the switching-out system is stopped. The invention is used for solving the problems of high loss, poor stability and low mixing depth during switching of a hybrid power system.
