[0052] The present invention will be further described below in conjunction with the drawings and embodiments.
[0053] A predictive control method for wind and solar storage models of microgrid includes the following steps:
[0054] Step (1): Predict the maximum output of wind turbines and photovoltaic power generation in the microgrid within a certain period of time through the prediction model;
[0055] Step (2): Taking the maximum output of wind power and photovoltaic power predicted in step (1) as constraints, perform online optimization of the output of wind turbines, photovoltaic power generation and energy storage batteries in the microgrid, and give the three in a certain period of time in the future Reference output;
[0056] Step (3): According to the real-time adjustable capacity of wind turbines and photovoltaic power generation, feedback and adjust the reference output of wind and solar energy storage in step (2) at the moment of control.
[0057] The predictive model in ...
