The invention discloses a power distribution network active and reactive cooperative dynamic optimization method and system, and the method comprises the steps: building a system power flow equation through node injection power, carrying out the linearization of the system power flow equation, obtaining a node voltage analysis expression, building a linearized power flow model according to the node voltage analysis expression, and carrying out the optimization of the power flow model. Calculating according to the linearized power flow model to obtain the voltage sensitivity of the PQ node and the balance node, and solving the constructed active-reactive power resource collaborative optimization model of the power distribution network according to the voltage sensitivity to obtain a schedulable operation plan, so that power grid personnel can schedule power resources according to the schedulable operation plan. According to the method, active and reactive collaborative optimization control of the power distrib
