| description | The invention discloses a dynamic coordination control method and system for multiple parallel virtual synchronous generators, and relates to the technical field of virtual synchronous generators, and the key points of the technical scheme are as follows: distributing a load power fluctuation value according to an output power fluctuation value of a new energy power generation unit and an energy storage state parameter of an energy storage unit; obtaining a power instruction of the virtual synchronous generator for VSG control; inputting the power instruction into a control model to obtain control parameters of VSG control; and inputting the control parameter into double-loop control, and processing the control parameter through an SPWM modulator to obtain a control signal for controlling the on-off of a switching tube in the inverter. According to the method, the difference of the residual capacity ratios of all the energy storage units after stage grid connection is completed can be small, the situation tha |
