[0068] With the continuous advancement of my country's smart grid construction, the technical level of load management terminals is also constantly improving. Traditional load management terminals usually require professionals to carry out complex installation and debugging processes, which consumes time and labor costs. At present, plug-and-play new load management terminals are in the early stages of development both at home and abroad, but have attracted widespread attention. In the construction of smart grids, load management terminals, as an important part of smart grids, are constantly innovating and developing. Foreign countries are relatively mature in technology development and product application, while domestic ones have certain advantages in price and adaptation to the domestic power grid environment. With the continuous advancement of technology and the continuous expansion of the market, plug-and-play load management terminals will become an important development direction for future load management and energy control.

[0069] To this end, the present invention proposes a load management terminal and a method and computing device for managing loads, which can improve the compatibility and scalability of the terminal, adapt to new energy systems, realize comprehensive management of multiple energy sources, improve energy reliability and sustainability, and simultaneously perform precise load control to avoid load overload and energy waste, optimize electricity usage habits, and improve energy utilization efficiency.

[0070] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

[0071] Figure 1 A schematic diagram showing the composition of a terminal module according to an example embodiment is shown.

[0072] Figure 2 A software architecture diagram according to an example embodiment is shown.

[0073] See also Figure 1 , Figure 1 The present application provides a plug-and-play new load management terminal, more specifically, including a main control module, a collection control module and an intelligent adjustment module, the main control module includes an intelligent algorithm module and an interface display module, the collection control module includes a pulse collection module, a remote signal collection module, an electric energy meter collection module, a load control module, an air conditioning management module, a charging pile collection module, etc., the intelligent adjustment module includes an energy efficiency management module, a demand side response module, an orderly charging module, etc. Figure 2 The software architecture diagram is shown in the figure.

[0074] According to some embodiments, the intelligent algorithm module is configured to: rely on real-time data for decision-making; collect and monitor these data in real time; and convert the load management problem into a linear programming problem. The interface display module is configured to: interact with the main control board of the smart energy unit; and display various data information. The pulse acquisition module is configured to: collect pulse signal sources through multiple acquisition channels; and save the collected pulse signal data. The electric meter acquisition module is configured to: read various metering data in the electric meter in real time. The air conditioning management module is configured to: collect air conditioning load power parameters and ambient temperature and humidity; and achieve bottom-line control of air conditioning load under emergency conditions of the power grid. The energy efficiency management module is configured to: monitor multiple energy types at the same time to meet the needs of comprehensive energy management; and conduct in-depth analysis of the collected energy data. The demand-side response module is configured to: predict future electricity demand; and evaluate the implementation effect of demand-side response projects.

[0075] According to some embodiments, the interface display module interacts with the main control board of the terminal through message queue telemetry transmission; the interface display module turns off the display screen of the terminal after 5 minutes of no operation on site.

[0076] The intelligent algorithm module needs to rely on a large amount of real-time data, such as current, voltage, and power, to make decisions, collect and monitor these data in real time, and transform the load management problem into a linear programming problem, which is used to optimize the load distribution of the power system, improve energy efficiency, and ensure stable operation of the system;

[0077] The interface display module interacts with the smart energy unit main control board through MQTT to display the electric energy meter equipment information, data information, alarm status, parameter information, etc., and turns off the screen after 5 minutes of no operation on site, so that the on-site operation and maintenance personnel can obtain the electrical information of the substation in time;

[0078] The pulse acquisition module has multiple acquisition channels and can collect multiple pulse signal sources at the same time. This enables the module to adapt to complex system requirements and monitor multiple devices or signal sources simultaneously. At the same time, the module has a data storage function and can save the collected pulse signal data for subsequent analysis and processing, which is of great significance for monitoring the operating status of equipment, statistical flow, and energy measurement.

[0079] The meter acquisition module can accurately read various metering data in the meter, including active power, reactive power, voltage, current, power factor, etc. It is connected to the communication interface of the meter via RS485 line to obtain the latest data of the meter in real time;

[0080] The air conditioning management module communicates with the measurement unit through RS485 to collect the power consumption parameters of the air conditioning load, communicates with the environment perception module through 5G / RS-485 to collect the ambient temperature and humidity, and communicates with the air conditioning control module through 5G / RS-485. The air conditioning control module achieves the minimum control of the air conditioning load in the emergency state of the power grid by connecting to the host remote control terminal;

[0081] The energy efficiency management module has the ability to monitor multiple energy types at the same time to meet the needs of different users for comprehensive energy management. Whether it is the electricity of industrial enterprises or commercial buildings, the energy efficiency management module can conduct comprehensive monitoring. At the same time, the collected energy data is deeply analyzed to understand the energy usage trend, peak and valley periods, energy consumption ratios of different equipment, etc. Through data analysis, energy waste links and potential energy-saving opportunities can be found;

[0082] The demand-side response module predicts future electricity demand through historical electricity consumption data, economic indicators and other information. Accurate demand forecasting can help power system operators prepare in advance and optimize power supply. At the same time, the implementation effect of the demand-side response project is evaluated, including load reduction, user participation, power system stability and other aspects. Through evaluation, the demand-side response strategies and measures are continuously improved.

[0083] The calculation of the dynamic priority is based on predefined rules and weights; the dynamic priority is adjusted in real time as the system status changes, and system resources are allocated to each module in order from high to low dynamic priority to ensure that high-priority modules respond and execute tasks in a timely manner.

[0084] According to some embodiments, the terminal system designs a universal standardized interface according to project requirements to ensure that each module of the terminal system matches the interface of different devices; for customized specific types of devices, a dedicated interface adapter is designed to convert the interface of each module of the terminal system into the interface type required by the device to achieve the connection between the module and the device. The terminal system adopts a plug-in and bayonet-type physical connection method for installation and removal on different devices; the terminal system adopts a wireless connection method to connect each module with a device that supports wireless communication without the need for a physical interface.

[0085] The terminal system of this application adopts a plug-and-play algorithm. The plug-and-play algorithm includes:

[0086] Physical interface identification and adaptation. Detection of the electrical characteristics of the device interface and the characteristics of the communication protocol. The interface type is preliminarily determined by detecting the voltage and current mode of the pin. For the communication protocol, the baud rate, data frame format, etc. are analyzed. If it is based on a USB interface, it is necessary to follow the USB protocol standard for identification and configuration; for the RS-232 interface, its specific level standards, such as negative logic level, and data format, such as start bit, stop bit, etc. are considered. This process can be regarded as a rule-based logical judgment algorithm, which matches the interface of the access device according to the predefined interface standard library. In wireless connection methods, such as Wi-Fi connection, it is necessary to follow the IEEE 802.11 standard for parameter configuration, including setting the service set identifier (SSID), security protocol (such as WPA2-PSK), frequency band (2.4GHz or 5GHz), etc. When the module attempts to connect to a Wi-Fi access point, it involves scanning available networks, sending probe request frames and receiving probe response frames, authentication, such as authentication through a shared key, and association, that is, sending association request frames and waiting for the access point to respond. These steps involve a series of network protocols and parameter configuration algorithms to ensure that the module can successfully connect to the wireless access point.

[0087] Protocol adaptation. Taking the 645 protocol as an example, the data frame format usually includes the start character, address field, control code, data length, data field, check code and end character. During the parsing process, the start character must be identified first, and then the address field, control code and other parts are read in the byte order specified in the protocol. The address field is used to identify the device address, and the control code is used to indicate the data transmission direction and operation type. For the check code part, a cyclic redundancy check (CRC) algorithm may be used to verify the correctness of the data transmission. Taking the CRC algorithm formula of CRC-16 as an example, let the information sending polynomial be M(x) and the generating polynomial be G(x) (for CRC-16, the commonly used generating polynomial is G(x)=x 16 +x 15 +x 2 +1), at the sending end, first shift M(x) left by n bits (n is the number of times the generating polynomial G(x), here n = 16), and get M(x)x n Then use M(x)x n Divide by G(x) to get the remainder R(x), then the CRC code sent is M(x)x n +R(x). At the receiving end, the received CRC code is divided by G(x). If the remainder is 0, the data transmission is considered correct.

[0088] Intelligent module collaborative scheduling. A dynamic priority is assigned to each module based on factors such as real-time load demand, energy supply status, and equipment operating status. The priority calculation can be based on some predefined rules and weights. For example, during peak power consumption and tight power supply periods, the priority weight of the load control module is set to the highest, while the priority weights of some non-critical data acquisition modules are set to a lower level, such as some pulse acquisition channels that do not require detailed monitoring for the time being. This priority will be adjusted in real time as the system status changes. During the scheduling process, system resources are allocated to each module in order of priority from high to low, such as CPU time, data transmission bandwidth, etc., to ensure that important modules can respond and execute tasks in a timely manner.

[0089] Load forecasting and control. The long short-term memory network algorithm (LSTM algorithm) is used mainly to process long-term dependencies in sequence data. In load forecasting, the power demand data is a time series, and LSTM can well capture the long-term trends, seasonal changes, and cyclical fluctuations in the time series. Gating includes input gates, forget gates, and output gates. The memory unit and gating mechanism are used to decide when to update and forget information, so as to effectively process complex patterns in time series. For example, when predicting the electricity demand of industrial enterprises, LSTM can accurately predict the electricity demand in the short term in the future, such as a few hours, based on the electricity consumption data of the past few days or even weeks, taking into account the different electricity consumption patterns on weekdays and holidays, and the changes in electricity consumption in different production shifts.

[0090] The innovative modular design of this application allows the terminal to be flexibly combined and expanded according to different needs. Users can choose different modules according to the actual load conditions, such as current monitoring module, power control module, communication module, etc., to achieve personalized load management solutions. This design not only improves the adaptability and flexibility of the terminal, but also reduces costs and facilitates users to upgrade and maintain. At the same time, the use of advanced intelligent control algorithms can automatically adjust the connection and disconnection of loads according to real-time load conditions and preset strategies. For example, during peak power consumption periods, the terminal can automatically disconnect some non-essential loads to give priority to the power supply of important equipment; during low power consumption periods, the terminal can automatically connect some delayable loads to make full use of power resources. This intelligent control algorithm not only improves the efficiency and accuracy of load management, but also achieves the goal of energy conservation and emission reduction.

[0091] Figure 3 A flow chart of a method for managing load terminals according to an example embodiment is shown.

[0092] See also Figure 3In S301, when the intelligent algorithm module is in the power control input state and the power control is effective, it determines whether the total load collected by the terminal reaches and / or exceeds the power setting value corresponding to the power control period at each full minute.

[0093] According to some embodiments, when the power control is in effect, it is determined at every full minute whether the total load collected by the terminal reaches or exceeds the power setting corresponding to the power control period, the power being given by the master station or calculated using parameters given by the master station.

[0094] In S303, when the total load reaches and / or exceeds the power setting value, the terminal issues a load over-limit alarm at a preset alarm time.

[0095] When the total load reaches or exceeds the power setting value at each full minute, the terminal issues a load overlimit alarm according to the preset alarm time. The alarm time is set by the master station and the default value is 3 minutes.

[0096] In S305, if the user does not take load reduction measures to make the total load lower than the current set value within the preset alarm time, the alarm is terminated and a tripping operation is performed until the total load is lower than the power set value.

[0097] According to some embodiments, based on the tripping order, a tripping action is performed on the controllable switch with the highest dynamic priority and power control in the closed position; if the total load is still higher than the power setting after tripping, the next round of alarms and tripping is performed in sequence from high to low in the order of the dynamic priority.

[0098] The terminal gives a load over-limit alarm at the set alarm time, indicating that the load is over-limit. At this time, the user should take load-reducing measures to make the total power lower than the current set value. If the user does not take load-reducing measures within the preset alarm time, and the load continues to exceed the limit and reaches or exceeds the power control alarm time, the alarm ends and the controllable switch with the highest priority and power control in the closed position is tripped according to the tripping order.

[0099] After tripping, if the current load is still higher than the control setting, the next round of alarms and tripping will be executed in sequence according to the priority, and so on, until the total load is lower than the power setting.

[0100] In S307, the intelligent algorithm module sends the decision result to the interface display module to realize timely notification and alarm.

[0101] According to some embodiments, the interface display module displays the alarm information on the display screen of the terminal for on-site operation and maintenance personnel to view.

[0102] The intelligent algorithm module sends the decision results to the interface display module and the remote control module. The interface display module displays the alarm information on the LCD screen for on-site operation and maintenance personnel to view. At the same time, the intelligent algorithm module sends the decision results to the remote control module. After the alarm time ends, the remote control module enters the tripping state and the indicator light turns red. The remote control module is an independent external component. It can be placed horizontally in the device through the pins and powered by the new load management terminal. The remote control module is used to receive control instructions issued by the new load management terminal to turn on and off the switches in the circuit. At the same time, the remote control module can also obtain real-time information such as the operating parameters and fault status of the controlled equipment, and feed back the equipment status information to the new load management terminal.

[0103] Figure 4 A schematic diagram of an implementation according to an example embodiment is shown.

[0104] Figure 5 A schematic diagram showing the appearance of a terminal according to an exemplary embodiment is shown.

[0105] See also Figure 4 , Figure 4 A schematic diagram showing an embodiment of the present application.

[0106] According to local project requirements, design universal standardized interfaces to ensure that the module can match the interfaces of different devices. For example, common interface standards such as USB, CAN, and RS232 can be used. These standards are widely used on many devices and can improve the compatibility of the module. For specific types of devices, special interface adapters can be designed to convert the module's interface to the interface type required by the device to achieve the connection between the module and the device.

[0107] Flexible connection methods such as plug-in and bayonet are used to facilitate the installation and removal of modules on different devices. For example, a module with a USB interface can be directly inserted into the USB port of the device and can be installed without the use of tools. The bayonet connection can fix the module to the device through a simple press or rotation operation. At the same time, the terminal system can also consider using wireless connection methods such as Bluetooth, Wi-Fi, etc., so that the module can be connected to devices that support wireless communication without the need for a physical interface, thereby improving the versatility of the module.

[0108] Write corresponding protocols, such as 645 protocol, Modbus protocol, etc., parse the corresponding access devices, and send the collected data to the data center of the main control module for calculation by the algorithm module.

[0109] The algorithm module makes decisions based on the collected data. When the power control is in effect, the total load collected by the terminal every hour reaches or exceeds the power setting corresponding to the power control period. The terminal gives a load over-limit alarm according to the set alarm time, indicating that the load is over-limit. At this time, the user should take load pressure measures to make the total power lower than the current setting. If the total load exceeds the limit continuously and reaches or exceeds the power control alarm time, the alarm ends and the controllable switch with the highest priority and power control in the closed position is tripped according to the tripping order. After tripping, if the current compliance is still higher than the control setting, the next round of alarms and tripping will be executed in sequence, and so on.

[0110] The algorithm module sends the decision results to the interface display module and the remote control module. The interface display module displays the alarm information on the LCD screen for on-site operation and maintenance personnel to view. The remote control module enters the tripping state after the alarm time ends and the indicator light turns red.

[0111] Developers from other units only need to design internal software functions to implement more advanced intelligent adjustment functions, such as demand-side response and orderly charging. These modules can be flexibly plugged into other new load management terminals for use, and have the characteristics of compatibility and high efficiency.

[0112] The plug-and-play new load management terminal proposed in this application has an overall structure of multiple components including a radio station, an algorithm module, a remote signal acquisition module, etc. The components are connected to the main control board through standard pin specifications, such as Figure 5 As shown in the schematic diagram, it realizes functions such as data collection, data storage, analysis and calculation, event recording, information feedback, and load regulation, and can meet the edge business needs of the new load management system. This application can improve the compatibility and scalability of the terminal, adapt to the new energy system, realize the comprehensive management of multiple energy sources, improve the reliability and sustainability of energy, and perform precise load control at the same time, avoid load overload and energy waste, optimize electricity usage habits, and improve energy efficiency.
