The invention relates to the technical field of power system application, and discloses a transient stability improvement-oriented network construction type energy storage adaptive control method. According to the control method, an energy storage self-adaptive transient support loop is introduced into a virtual synchronous machine module in a traditional networking type energy storage system control structure to control the injection power of an energy storage system to be changed in real time so as to provide transient stability support for the system. The operation scheme disclosed by the invention is simple in control structure and convenient in parameter adjustment, and the network construction type energy storage system introduced with the energy storage self-adaptive transient support loop can ensure stable operation of the system under a fault condition when transient large signal disturbance occurs in the system, so that the reliability of the system is improved. And the problem of large-scale off-ne
