[0002] With the development and transformation of new power systems, the demand for interactive resources on the demand side continues to expand. During the peak electricity consumption period in summer, the air conditioning load can sometimes reach 40% of the total electricity load and maintain an upward trend. Therefore, the load of residential air conditioning equipment can adjust its own load within a certain time range to participate in grid interaction through platform access, intelligent transformation, strategy formulation and other means. At present, large-scale air conditioning equipment load clusters have gradually become one of the most typical and abundant resources on the demand side. It can alleviate the peak power consumption pressure of the power grid and better regulate peak power consumption. However, the current research field of air conditioning equipment demand response interaction still lacks detailed theoretical research on the digital-physical hybrid simulation technology for multi-protocol air conditioning equipment protocol conversion and unification, and demand response interaction capability certification.

[0087] Embodiment 1:

[0088] An air conditioning digital-physical hybrid simulation system, such as Figure 1 As shown:

[0089] Air conditioning digital simulation subsystem, physical control machine and interactive control subsystem;

[0090] The air conditioning digital simulation subsystem is used to simulate the operating parameters of the air conditioning system, and send the operating parameters to the physical control machine through the interactive control subsystem, and is also used to receive the control instructions sent by the physical control machine through the interactive control subsystem, and regulate the simulated air conditioning system according to the control instructions;

[0091] A physical control machine, used for receiving the operating parameters forwarded by the interactive control subsystem, calculating control instructions according to the operating parameters, and sending the control instructions to the air conditioning digital simulation subsystem through the interactive control subsystem;

[0092] The interactive control subsystem is used to forward operating parameters and control instructions between the air-conditioning digital simulation subsystem and the physical control machine, and is also used to monitor the operating parameters. After receiving the authentication instructions sent from the outside, it is also used to determine the operating status of the air-conditioning system according to the operating parameters and return demand response information to the outside according to the operating status.

[0093] A specific example of an air conditioning digital-physical hybrid simulation system is Figure 2 shown.

[0094] The air conditioning digital simulation subsystem simulates and calculates the operating parameters of the air conditioning system (such as temperature, air flow, pressure and energy, etc.) based on the air conditioning simulation unit (specifically LABVIEW in this embodiment), and interacts with the interactive control subunit and the physical control machine through the numerical interaction unit (specifically MATLAB program in this embodiment).

[0095] The physical control machine includes a physical controller, a digital-to-analog converter (i.e., D / A converter) and an analog-to-digital converter (i.e., A / D converter). The digital input parameters (i.e., operating parameters, temperature, pressure, etc.) are converted into analog quantities through the digital-to-analog converter. Then, the analog control instructions are obtained after calculation by the physical controller. After being converted into digital instructions (i.e., control instructions) through the analog-to-digital converter, they are returned to the device actuator in the air-conditioning digital simulation subsystem to regulate the simulated air-conditioning system and complete the seamless embedding of the physical system.

[0096] The interactive control subunit includes a communication module, a storage module, a metering module, a safety module and a microprocessor. In the default operating state, the interactive control subunit receives the digital parameters (i.e., operating parameters) calculated in the air-conditioning digital simulation subsystem and transmits them to the physical control machine. At the same time, it transmits the control instructions output by the physical control machine to the air-conditioning digital simulation subsystem, thereby enabling the air-conditioning digital simulation subsystem to take the next step.

[0097] The interactive control subunit is the core part of the air-conditioning digital-physical hybrid simulation in the present invention. The subsystem can call the program expansion interface of MATLAB to achieve connection with the air-conditioning digital simulation subsystem, realize real-time data processing, monitoring and online setting functions, so as to realize the monitoring and dynamic adjustment of real-time operating parameters in the air-conditioning digital simulation subsystem, and timely discover and eliminate faults; with the help of historical electricity consumption data and other information in the storage module, various types of electricity consumption data curves and charts can be drawn in combination with specific business needs; when facing the demand response capability certification business, after receiving the certification instruction, the relevant information required for the certification business can be transmitted to the external demand response capability certification system with the help of the communication module.

[0098] The security module described in this module has a data encryption function and is compatible with the general international standard encryption algorithm. It can encrypt the key authentication data information interacting between the authentication master station and the air-conditioning equipment when the air-conditioning equipment participates in the grid interaction capability authentication, thereby ensuring the reliability and security of the communication. The security module is connected to the microprocessor for communication.

[0099] The metering module calculates the actual power consumption data of the household air conditioner in different operating states, including cooling, heating, standby, etc., through digital signals (i.e., operating parameters), and provides raw data for energy efficiency analysis and management. The metering module is connected to the microprocessor for communication.

[0100] The storage module is mainly responsible for storing the power consumption data obtained by the metering module. In addition, the interactive capability authentication information of the air-conditioning equipment (i.e., demand response capability authentication information) and the relevant configuration parameters required for operation, the system program to maintain the normal operation of the entire interactive control subunit, etc. are also stored here. The storage module is in communication connection with the microprocessor.

[0101] In addition to the serial communication function, the communication module also integrates wireless communication technologies such as Wi-Fi and cellular networks, which significantly enhances the flexibility and convenience of the system compared to wired communication. By connecting with the MATLAB software platform and using the Modbus protocol to ensure efficient data exchange and command reception within the simulation model (i.e., the air-conditioning digital simulation subsystem), the normal operation of the air-conditioning equipment simulation model is realized. At the same time, communication with the external demand response capability certification system is also realized, which can accurately process the sending and receiving of data packets, support data read and write operations on the communication bus, and efficient access to the storage module. The communication module is connected to the air-conditioning digital simulation subsystem, the physical control machine, and the microprocessor respectively.

[0102] The microprocessor is connected to the communication module, the storage module and the metering module, and is used to manage and control the operation of the interactive control subunit. At the same time, according to the received remote demand response capability authentication instruction (i.e., authentication instruction), the real-time operation status of the air-conditioning simulation model collected by itself, the demand response capability authentication information of the device in the memory, and the local communication protocol category and other information can be packaged to generate demand response information, and transmitted to the external demand response capability authentication system in accordance with the communication protocol format used by itself with the help of the communication module. Among them, the operation status of the simulated air-conditioning system is calculated based on the operation parameters.

[0103] The interactive control subsystem also includes an interactive interface, which is connected to the communication module, the air conditioning digital simulation subsystem and the physical control machine; the interactive interface is used to provide an interface for data interaction between the communication module and the air conditioning digital simulation module, and between the communication module and the physical control machine.

[0104] Guarantee of simulation real-time performance:

[0105] In addition, real-time performance is crucial in air-conditioning digital-physical hybrid simulation. In order to achieve the goal of real-time simulation, the key lies in solving the real-time data exchange and communication problems between the interactive control subsystem and the air-conditioning digital simulation subsystem, between the interactive control subunit and the physical control machine, and seamless integration with advanced software platforms such as MATLAB and LABVIEW.

[0106] Data exchange and communication between LABVIEW and MATLAB software platforms are realized through advanced Component Object Model (COM) technology. Socket technology based on TCP / IP protocol is used to efficiently realize data exchange and communication between MATLAB and interactive control subsystem. These technologies ensure fast and stable data transmission and interactive operation between the two platforms.

[0107] For the connection between the interactive control subsystem and the physical control machine, accurate and low-latency data conversion is achieved by using analog-to-digital converters and digital-to-analog converters, and the efficient communication capabilities of the Modbus protocol are used to quickly set and respond to the physical control machine, ensuring the real-time performance between the interactive control subsystem, the physical control machine and the air-conditioning digital simulation subsystem, and realizing highly synchronized real-time simulation among the subsystems and software platforms of the air-conditioning digital-physical hybrid simulation system.

[0108] Air conditioning equipment demand response capability certification information:

[0109] After receiving the demand response capability certification instruction, the air conditioning equipment needs to transmit the required demand response capability certification information to the external demand response capability certification system. The demand response capability certification information includes five categories: the device's responsive signal type, supported interactive scene type, adjustable mode, flexibility in participating in demand response, and device intelligence level. Figure 3 Specifically:

[0110] The types of responsive signals include direct control signals, control decision signals, reduction signals, and electricity price signals;

[0111] Supported interactive scenarios include new energy consumption and peak load shifting;

[0112] The adjustable modes include mode control and gear control, among which mode control includes managed control and self-control;

[0113] The flexibility of participating in demand response mainly considers whether there is a function to select the degree of participation and whether there is a function to exit the response midway;

[0114] The level of equipment intelligence mainly considers whether the equipment has remote control capability, direct control function, control decision function, reduction decision function, and price decision function. Among them, whether the equipment has direct control function, control decision function, reduction decision function, and price decision function can be set as a lower-level indicator of whether it has sub-learning ability. The indicators of equipment intelligence level also include whether it has wifi function.

[0115] Embodiment 2:

[0116] A digital-physical hybrid simulation method for air conditioning, such as Figure 4 As shown, including:

[0117] Step A1: obtaining the operating parameters of the air-conditioning system simulated by the air-conditioning digital simulation subsystem of the air-conditioning digital-physical hybrid simulation system, and sending the operating parameters to the physical control machine of the air-conditioning digital-physical hybrid simulation system;

[0118] Step A2: Obtain the control instruction returned by the physical control machine, and send the control instruction to the air conditioning digital simulation subsystem;

[0119] Among them, the air-conditioning digital-physical hybrid simulation system is the air-conditioning digital-physical hybrid simulation system as described above, and the air-conditioning digital-physical hybrid simulation method is applied to the interactive control subsystem of the air-conditioning digital-physical hybrid simulation system.

[0120] When the air conditioning hybrid simulation system (ie, air conditioning digital-physical hybrid simulation) does not receive a demand response capability authentication instruction, the air conditioning digital simulation subunit is set to be in a dynamic stable operation state at the current moment.

[0121] The specific process of the simulation is as follows:

[0122] The air conditioning digital simulation subsystem uses the MATLAB software platform and the interactive control subsystem to communicate over the network to transmit the digital data of the operating parameters such as temperature, flow, pressure, etc. calculated by the air conditioning digital simulation subsystem at the current moment to the interactive control subsystem in real time.

[0123] The data interaction between the interactive control subsystem and the physical control machine is mainly completed by the digital-to-analog converter, the analog-to-digital converter and the Modbus serial communication. The interactive control subsystem receives the real-time simulation data (i.e., operating parameters), stores it in the storage module immediately, performs data analysis and useful information extraction, and then uses the Modbus serial communication to transmit the digital quantity signal (i.e., operating parameters) calculated by the air conditioning digital simulation subsystem to the physical control machine.

[0124] The digital-to-analog converter converts the digital signal into a 4-20mA analog signal and passes it to the physical controller. The physical controller then uses the obtained simulated thermal physical data analog quantity to calculate the next control instruction. The analog-to-digital converter converts the 4-20mA simulation module (i.e., air conditioning digital simulation subsystem) control instruction analog quantity calculated by the physical controller into the corresponding digital quantity, and then uses Modbus serial communication to return the control instruction to the interactive control subsystem.

[0125] The further interactive control subsystem uses the network communication through the MATLAB software platform to send the next moment's control instructions to the air conditioning digital simulation subsystem.

[0126] The air conditioner simulated by the air conditioner digital simulation subsystem starts to adjust its own operating state after receiving the setting instruction. At this point, the air conditioner simulation model (i.e., the air conditioner digital-physical hybrid simulation system) has completed an operating cycle.

[0127] After obtaining the operating parameters of the air conditioning system in step A1, the following steps are also included: certifying the demand response capability of the simulated air conditioning, specifically: Figure 5 As shown, including:

[0128] Step B1: after receiving the authentication instruction sent from the outside, determine the operating state of the air conditioning system according to the operating parameters of the air conditioning system;

[0129] Step B2: Returning demand response information to the outside according to the operating status of the air conditioning system;

[0130] The operating parameters of the air conditioning system are simulated and calculated by the air conditioning digital simulation subsystem of the air conditioning digital-physical hybrid simulation system, and the air conditioning digital simulation subsystem regulates and controls the simulated air conditioning system according to the control instructions sent by the physical controller of the air conditioning digital-physical hybrid simulation system;

[0131] The air-conditioning digital-physical hybrid simulation system is the air-conditioning digital-physical hybrid simulation system as described above, and the authentication method is applied to the interactive control subsystem of the air-conditioning digital-physical hybrid simulation system.

[0132] The above process is the process flow of steps performed by the air conditioner digital-physical hybrid simulation system during the demand response certification process. If the external certification system is taken into account, the entire multi-protocol air conditioner equipment demand response capability certification business architecture is as follows: Figure 6 The multi-protocol air conditioning demand response capability certification business process is as follows:

[0133] Demand response capability authentication command is sent: the demand response capability authentication master station sends the authentication command (i.e. Figure 6The air conditioning capability authentication instruction in the demand response capability authentication command is sent to the multi-protocol unified access device. The demand response capability authentication master station and the multi-protocol unified access device are both existing devices and will not be described in detail.

[0134] Instruction encapsulation and forwarding: The multi-protocol unified access device encapsulates the received authentication instructions into different protocol formats so as to send them to the air-conditioning equipment that supports the corresponding protocol formats.

[0135] Initial state of the air-conditioning hybrid simulation model: Before receiving the authentication instruction, the air-conditioning digital simulation subunit is in a dynamic stable operation state.

[0136] Demand response capability authentication instruction reception: The communication module in the interactive control subsystem of the air-conditioning digital-physical hybrid simulation system receives the authentication instruction from the multi-protocol unified access device.

[0137] Signal processing: The received instructions are transmitted to the microprocessor through RS232, RS485, USB and other interfaces, and the microprocessor performs signal processing and analysis on the instructions.

[0138] Information packaging: The microprocessor packages the real-time operating status of the air-conditioning system simulated by the air-conditioning digital simulation subsystem stored in the storage module, the demand response capability authentication information of the device, and the local communication protocol category. Among them, the operating status is determined according to the operating parameters of the air-conditioning system.
