| description | The invention discloses a model parameter identification method and device and computer equipment. The method comprises the following steps: constructing a grid-connected simulation model of the photovoltaic power generation system based on structural components included in the photovoltaic power generation system; generating test data of the photovoltaic power generation system at the grid-connected point based on the predetermined test condition parameters and the grid-connected simulation model; based on the test data, changing the working state of the photovoltaic power generation system to obtain change result data of the photovoltaic power generation system at the grid-connected point; determining an equivalent circuit model of the grid-connected simulation model based on the change result data; and based on the change result data, identifying parameters of the equivalent circuit model by adopting a non-mechanism black box method to obtain model parameters of the equivalent circuit model corresponding t |
