The modeling machine 11 has been described in the first embodiment, and will not be described here again.
The simulator 22 is used for collecting energy supply information of each equipment model in the physical model 221 of the integrated energy system through the data collection interface 222.
Specifically, after compiling and running the physical model 221 of the integrated energy system, the simulator 22 may collect, through the data collection interface 222, energy supply information of each device model in the physical model 221 of the integrated energy system. The simulator 22 directly collects and stores the energy supply information of each equipment model after the physical model 221 of the integrated energy system operates normally, so that the collection speed can be effectively increased, and the time for making energy management and optimizing scheduling strategies is saved.
The monitoring module 231 is configured to monitor the energy supply information of each device model acquired from the emulator 22, and when it is determined that the preset condition is satisfied, send the energy supply information of each device model to the acquiring module 232.
In a specific implementation, the monitoring module 231 may monitor the energy supply information of each device model obtained from the simulator 22 in real time, and when determining that the preset condition is met, send the energy supply information of each device model obtained from the data acquisition interface 222 to the obtaining module 232, so as to effectively improve the obtaining speed of the energy supply information of each device model obtained by the upper computer.
In one example, the preset condition is that the energy supply information is abnormal, such as the energy for the equipment model is reduced to 0, the energy for the equipment model is increased sharply, the energy for the equipment model is reduced to 0, etc.
In another example, the preset condition is that the monitoring module 231 receives an adjustment instruction, which may be triggered by one skilled in the art.
In one example, the provisioning information has multiple types, and when the provisioning information of the type a satisfies the preset condition, the monitoring module 231 sends the provisioning information of the type a to the obtaining module 232, and the obtaining module 232 obtains the procedure of adjusting the provisioning information of the type a only for the provisioning information of the type a.
The obtaining module 232 is configured to receive the energy supply information of each device model, and obtain a program according to the energy supply information of each device model.
Specifically, the acquiring module 232 may acquire the program based on the energy supply information of each device model after receiving the energy supply information of each device model sent from the monitoring module 231.
In the specific implementation, the acquisition module is built with a programming environment, so that a user can develop a program for adjusting the energy supply information of each equipment model in real time based on high-level languages such as C++, java, python and the like, and the flexibility and operability of energy management and optimal scheduling strategy formulation of the comprehensive energy system can be further improved.

Specifically, after the acquisition module 232 acquires the program, the monitoring module 231 calls the program by calling the interface, that is, executes the program at the host computer 23, generates a control instruction corresponding to the program, and the monitoring module 231 transmits the generated control instruction to the emulator 22. The control instruction is used for instructing each equipment model to adjust the energy supply information of each equipment model;
in a specific implementation, the program acquired by the acquiring module 232 is different, the control instruction generated by the monitoring module 231 is different, and the comprehensive energy system can be comprehensively tested and regulated by using different control instructions.
Such as: the program for adjusting the energy supply information of each device model is an economic optimization scheduling algorithm, and accordingly the monitoring module 231 generates an economic optimization scheduling control instruction. The program for adjusting the energy supply information of each equipment model can also comprise a multi-energy cooperative complementary control algorithm, an energy maximization cascade utilization algorithm, a system voltage optimization algorithm, a system power optimization algorithm, a system stability optimization algorithm, a system situation awareness and safety control algorithm, a fault diagnosis and system self-healing algorithm, a parallel off-network switching algorithm and the like.
The emulator 22 is further configured to receive a control instruction through the instruction interface 223, and issue the control instruction to each device model to operate, so as to adjust the energy supply information of each device model.
