Abstract: The optical-storage independent microgrid system has complex structure, and the change of load parameters will lead to insufficient stability of output voltage. Therefore, a coordination control method for output voltage of optical-storage independent microgrid based on adaptive optimisation is proposed. The topological graph of optical-storage independent microgrid is constructed to obtain the load state parameters of optical-storage independent microgrid for constructing the optimisation model of load state parameters. Through adaptive adjustment of step and square wave response, the load state optimisation parameters are obtained by fusion processing, and then the output voltage of the optical-storage independent microgrid is constrained. The output voltage stability of optical-storage independent microgrid is adjusted, and the coordination control of output voltage stability of optical-storage independent microgrid is realised. The simulation results show that the optical-storage independent microgrid controlled by this method has good output voltage stability and strong adaptive parameter optimisation ability.

Keywords: microgrid; output voltage; adaptive control; coordination control; load parameters; step response.
