[0079] ;

[0080] In the embodiment of the present invention, the external power supply has a limit on the rated charging power, so its constraint is the rated charging power. Refers to the rated charging power of the external power source;

[0084] The second discharge constraint condition includes:

[0085] ;

[0086] Indicates the upper limit of the instantaneous power of the mobile power supply; express The total power change of the external power supply at the moment;

[0087] Step S103, inputting the current state of charge and state of discharge into the first layer of the double-layer MPC (Model predictive control) model to obtain the predicted charging power and the predicted discharging power;

[0088] In a preferred embodiment of the embodiments of the present invention, the charging state quantity and the discharging state quantity at the current moment are input into the first layer MPC in the double-layer MPC model to obtain the predicted charging power and the predicted discharging power, including: simulating and generating the charging state quantity and the discharging state quantity at the current moment to generate multiple groups of simulated charging state quantities and simulated discharging state quantities at different moments; inputting the simulated charging state quantity and the simulated discharging state quantity into the first layer MPC in the double-layer MPC model to obtain the predicted charging power and the predicted discharging power.

[0089] Specifically, the upper and lower value ranges of the data can be set first, and then the upper and lower value ranges of the data are passed to the data generation plug-in, and the upper and lower value ranges are applied to the data generation plug-in, and the data generation plug-in is controlled to output the simulated charging state quantity and simulated discharge state quantity that meet the upper and lower value ranges, and the simulated charging state quantity and simulated discharge state quantity are bound to different moments to obtain the simulated charging state quantity and simulated discharge state quantity at different moments.

[0090] Step S104: constraining the predicted charging power and the predicted discharging power under charging and discharging constraint conditions according to the charging objective function and the discharging objective function, performing rolling optimization in the time domain, and obtaining a plurality of first power control parameter vectors;

[0091] In an embodiment of the present invention, after obtaining the predicted charging power, the predicted discharging power, the charging and discharging constraints, and the charging objective function, the predicted charging power and the predicted discharging power at different times are subjected to rolling optimization in the time domain under the optimization objective function and the constraints to obtain multiple first power control parameter vectors.

[0092] Step S105, judging whether the multiple power control parameter vectors meet the preset threshold range, when the multiple power control parameter vectors meet the preset threshold range, inputting the predicted charging power and the predicted discharging power into the second layer MPC in the double-layer MPC model, obtaining multiple second power control parameter vectors, iterating the charging objective function and the discharging objective function until convergence, and obtaining the third charging and discharging control parameter;

[0093] The preset threshold range may be any value set by those skilled in the art, and the embodiments of the present invention do not impose excessive restrictions on this.

[0094] Specifically, the preset threshold range can be [0, Ps, w], Ps, w represents the theoretical rated power of the electrical equipment, and the rated power is limited. If the value of the power control parameter vector does not meet the preset threshold range, the corresponding power control parameter vector is discarded, and the process returns to the step of obtaining the charging state quantity of the mobile power supply at different times and the discharging state quantity at different times, and inputting the charging state quantity and the discharging state quantity at the current time into the first layer MPC in the double-layer MPC model to obtain the predicted charging power and the predicted discharging power.

[0095] On the other hand, in addition to the power parameters, the power control parameter vector can also be judged according to the voltage threshold and the current threshold, and the multiple power control parameter vectors are judged whether they meet the preset threshold range. When the multiple power control parameter vectors meet the preset threshold range, the predicted charging power and the predicted discharging power are input into the second layer MPC in the double-layer MPC model to obtain multiple second power control parameter vectors, and the charging objective function and the discharging objective function are iterated until convergence to obtain the third charging and discharging control parameters, including:

[0096] Specifically, the power control parameter vector includes charging and discharging voltage parameters, charging and discharging current parameters, wire size parameters, etc., and the embodiment of the present invention does not impose too many restrictions on this;

[0097] The discharge voltage parameter and the charge and discharge current parameter are compared with the corresponding voltage threshold and current threshold. When the discharge voltage parameter and the charge and discharge current parameter are less than the corresponding voltage threshold and current threshold, the predicted charging power and the predicted discharge power are input into the second layer MPC in the double-layer MPC model to obtain multiple second power control parameter vectors, and the charging objective function and the discharging objective function are iterated until convergence to obtain the third charge and discharge control parameter.

[0098] For example, the voltage threshold may be Vs,w, where Vs,w represents the voltage rated power of the electrical equipment; the current threshold may be Is,w, where Is,w represents the current rated power of the electrical equipment; the voltage parameter and the current parameter in the power control parameter vector are compared with the voltage threshold and the current threshold; when the voltage parameter and the current parameter are less than the threshold, the predicted charging power and the predicted discharging power are input into the second layer MPC in the double-layer MPC model; a rolling optimization solution is performed in the time domain to obtain multiple second power control parameter vectors; the charging objective function and the discharging objective function are iterated until convergence to obtain the third charging and discharging control parameter; when the voltage parameter and the current parameter are greater than the threshold, the corresponding power control parameter vector is discarded, and the process returns to the step of obtaining the charging state quantity and the discharging state quantity of the mobile power supply at different times, and the charging state quantity and the discharging state quantity at the current time are input into the first layer MPC in the double-layer MPC model to obtain the predicted charging power and the predicted discharging power.

[0099] It should be noted that the two-layer MPC model in the embodiment of the present invention is only an example of the present application. The accuracy of power simulation of the present application can also be improved by using two-layer MPC models of other types or other structures, so as to achieve the effect of accurately controlling the power of external power supplies, the power of electrical equipment, and the power of mobile power supplies at different times, reduce power fluctuations, and increase the standard life and service life of equipment.

[0100] Step S106: Control the charging and discharging power of the mobile power source by using the third charging and discharging control parameter.

[0101] Furthermore, after obtaining the third charge and discharge control parameter, the charge and discharge power of the mobile power source can be controlled by the third charge and discharge control parameter, thereby achieving the effect of accurately controlling the charge and discharge power and improving the standard life and service life of the equipment.
