## 2 Modeling of the Coordination Control System
### Coordinate Control System Model  
In this paper, MATLAB software is implemented to analyze the coordination control strategy of the heat and heat reservoir of the steam heating in a fire power plant. The developed model has been schematically illustrated in Figure 2.  
Figure 2 depicts the coupled control model of the coordinated control system and the digital electro-hydraulic control systems that are connected by valve opening. The coordinated control system is a model for the coordinated control of regulating valve opening, coal combustion, and heat storage power. The digital electro-hydraulic control system is a power control model. Here, the transfer function is modeled as a simplified coordinated control system. The digital electro-hydraulic control system model is coupled to using this transfer function model via the opening of the regulating valve. Facilitates simulation on MATLAB to analyze the primary frequency function of the coordinated control of coupled thermal storage systems [18; 19]. Based on a steam heating molten salt heat storage/heat release system with a series double closed-loop PID control, the series double closed-loop PID algorithm regulates the combined output power of the thermal power unit and the fused salt heat storage in accordance with the frequency variation of the power grid. In the operation of the 45% THA operating condition of the FPU, the demand for a depth of 35% of the THA FPU depth is appropriately met. Concerning the steam volume of the molten salt heat exchanger system vapor, the molten salt heat exchanger lessens the unit by 10% THA. By the same principle, when the heat exchanger needs to release the corresponding heat, the heat turbulence is caused by the steam turbine. Combined with the actual condition of the operation unit, the heat capacity of the hot salt reservoir in the model is small at 80 MWh, and the heat storage and the heat period are no more than 12 h [20].

The dynamic power distribution strategy of molten salt heat storage and turbine boiler master control coordinated control for real-time dispatching of the power grid has been demonstrated in Figure 3.  
When the power grid load dispatching center is issued by the power grid load dispatching center, the power distribution control center calculates whether the power of the heating system can adjust the power requirement. This process is the rapid response of the heat storage process, and the power of the unit is quickly lessened by pumping the steam. If the demand power is not adjusted, the corresponding regulation of the heat storage system and the FPU is, respectively, evaluated. The unit coordinates of the control system and the reservoir heat system simultaneously act to meet the power change requirements of the grid [21]. The coordinated control logic of the thermo-energy unit of the coupled melting salt storage system has been illustrated in Figure 4.  
When the power grid load scheduling center sends down the load instruction, the storage system's heat storage process quickly responds, and by adjusting the range of the power increase, the steam and the steam instructions start to act. First, the steam valve is opened, and the power of the unit is swiftly reduced by the opening degree of the

The power distribution control center is evaluated by the dynamic power distribution control center by simultaneously evaluating the regulation power of the energy storage system and the FPU, the unit coordination control system, and the reservoir heat system.
