[0049] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.
[0050] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application.

[0052] Traditional AGC is a relatively simple and homogeneous control architecture that achieves deterministic control where the source follows the load. That is, the load is fluctuating and uncontrollable, but the power generation side is controllable. AGC tracks load changes by adjusting the power generation.
[0053] However, modern power systems tend to integrate more new energy and renewable resources, with large-scale distributed access of new energy and renewable resources to the power system.
[0054] Different power generation types exhibit significant differences in regulation efficiency, response time, and control accuracy. Specifically, thermal power AGC systems have the highest regulation rate but the longest response time; hydropower AGC systems have a moderate regulation rate but control more objects; and photovoltaic and wind power AGC systems have lower regulation rates but shorter response times. Therefore, different power generation types place varying requirements on AGC systems in terms of regulation rate, response time, regulation accuracy, and pass rate.
[0055] This results in the generation side of traditional AGC becoming fluctuating and uncertain, and its controlled objects becoming complex and heterogeneous. AGC needs to cope with both random load fluctuations and the drastic and rapid fluctuations of new energy sources. As a result, the underlying theoretical foundation and infrastructure of traditional AGC will be fundamentally incompatible, naturally leading to poor collaborative control performance.
[0056] To address the aforementioned problems, this application provides an automatic power generation control method and related apparatus.
[0057] Optional, see Figure 1 This application provides a flowchart of an automatic power generation control method.
[0058] like Figure 1As shown, the automatic power generation control method includes the following steps:
[0059] Step 101: Obtain the set of operating parameters for the generator set. The set of operating parameters includes at least one set of operating parameters corresponding to a power generation type.
[0060] It should be noted that the operating parameter set includes operating parameter groups corresponding to different power generation types, and the operating parameter set includes at least one operating parameter group corresponding to one power generation type. The operating parameter group can also be called a configurable input parameter set, which includes, but is not limited to, the total active power target value, the actual total active power value, the system rated frequency, the system actual frequency, the upper limit of regulation, the lower limit of regulation, the rate of increase of regulation, the rate of decrease of regulation, the dead zone setpoint, and the preset allocation mode. Among these, the total active power target value, the preset allocation mode, and the dead zone setpoint define the objectives and logic of automatic power generation control; the upper limit of regulation, the lower limit of regulation, the rate of increase of regulation, the rate of decrease of regulation, and the system rated frequency define the physical and safety boundaries of automatic power generation control operation and unit regulation; the actual total active power value and the actual system frequency provide the real-time basis for calculation, controlling the real-time feedback of automatic power generation control, used for comparison with the target and benchmark, and calculating key control inputs such as regional control deviation.
[0061] The specific set of operating parameters of the generator set can be obtained through the SCADA system (Supervisory Control And Data Acquisition). This system has powerful data acquisition, storage, monitoring, alarm and data analysis capabilities. In the automatic power generation control method provided in this application embodiment, it is mainly responsible for acquiring, storing, monitoring, alarming and forwarding various operating parameters.
[0062] Optionally, a set of configurable input parameters for the generator set can be obtained from the data acquisition and monitoring control system. The set of configurable input parameters includes the total active power target value, the total active power actual value, the system rated frequency, the system actual frequency, the upper limit of regulation, the lower limit of regulation, the rate of increase of regulation, the rate of decrease of regulation, the dead zone setpoint, and the preset allocation mode.
[0063] The set of operating parameters consists of the total active power target value, the total active power actual value, the system rated frequency, the system actual frequency, the upper limit of adjustment, the lower limit of adjustment, the adjustment rise rate, the adjustment fall rate, the dead zone setting value, and the preset allocation mode.
[0064] Step 102: Call the automatic power generation control algorithm function block to process the set of operating parameters and determine the power generation type corresponding to each group of operating parameters in the set of operating parameters; the automatic power generation control algorithm function block encapsulates multiple automatic power generation control algorithm programs.
[0065] It should be noted that the automatic power generation control algorithm function block provided in this application can realize automatic power generation control for different power generation types. As long as the operating parameter groups of different power generation types are input into the automatic power generation control algorithm function block, the function block can calculate and output the corresponding operating control parameter group based on the operating parameter group of the power generation type.
[0066] The automatic power generation control algorithm function block encapsulates multiple automatic power generation control algorithm programs, each capable of calculating operating parameter sets for different power generation types. The construction process of this automatic power generation control algorithm function block can be as follows:
[0067] 1> Obtain the automatic power generation control algorithm set, which includes various automatic power generation control algorithms corresponding to different power generation types.
[0068] First, obtain the automatic power generation control algorithms corresponding to different power generation types. The core objectives of the automatic power generation control algorithms corresponding to different power generation types are the same, but their physical characteristics, constraints and performance are very different. They have highly differentiated designs and processing at the control strategy and algorithm level.
[0069] Specifically, different power generation types exhibit significant differences in characteristics such as regulation speed, regulation accuracy, energy constraints, and regulation costs. For example, thermal power has a slow regulation speed (minutes), high regulation accuracy, energy constraints that are almost unlimited when energy is plentiful, high regulation costs (mainly fuel costs), bidirectional regulation (up / down), and provides inertia. Hydropower has an extremely fast regulation speed (seconds), high regulation accuracy, energy constraints limited by reservoir capacity, low regulation costs, bidirectional regulation (up / down), and provides inertia. Wind and solar power have fast regulation speeds (seconds, depending on the inverter), relatively high regulation accuracy, energy constraints limited by natural conditions and uncontrollable, zero marginal cost of regulation but with opportunity costs, primarily downward regulation, and do not provide inertia but can provide virtual inertia. Energy storage batteries have an extremely fast regulation speed (milliseconds), extremely high regulation accuracy, severely limited by state of charge, regulation costs including cycle life loss, bidirectional regulation (charge and discharge), and do not provide inertia.
[0070] The automatic power generation control algorithm function block can be understood as a unified but highly intelligent collaborative optimization algorithm. Different power generation types have different internal models and decision-making logics. This function block can achieve collaborative processing of heterogeneous resources of different power generation types.
[0071] 2> The automatic power generation control algorithms are processed by programmable logic controller (PLC) software to obtain an automatic power generation control algorithm program set.
[0072] Specifically, the automatic power generation control algorithms are written into automatic power generation control algorithm programs using the PLC (Programmable Logic Controller) programming language, resulting in an automatic power generation control algorithm program set.
[0073] 3> Encapsulate the automatic power generation control algorithm program assembly into an automatic power generation control algorithm function block.
[0074] The automatic power generation control algorithm assembly is encapsulated into an automatic power generation control algorithm function block.
[0075] In traditional AGC systems, the automatic power generation control algorithm is usually embedded in dedicated hardware or closed software, which is difficult to optimize and upgrade, and the upgrade cost is high. As a result, the automatic power generation control algorithm in dedicated hardware or closed software is seriously lagging behind the development of technology and actual needs.
[0076] The automatic power generation control algorithm function block provided in this application embodiment can achieve modularity and code reuse. It can be written once and used in multiple places, which greatly reduces duplicate code and improves development efficiency. If the algorithm needs to be modified, only the function block needs to be modified, and all places that call it will be automatically updated, avoiding errors and inconsistencies that may be caused by repeated modifications.
[0077] For example, see Figure 2 The flowchart of the automatic power generation control method provided in this application is shown in the figure.
[0078] like Figure 2 As shown, the construction process of the automatic power generation control algorithm functional block is as follows:
[0079] First, using PLC programming software, the AGC algorithm is written into an algorithm program according to the requirements of the AGC algorithm, and then the algorithm program is encapsulated into an AGC algorithm function block. Next, the AGC algorithm function block is downloaded to a software PLC (Software Programmable Logic Controller) for program simulation and debugging, continuously optimizing the algorithm. Once the simulation results meet the production requirements, it is deployed to the field for operation and control.
[0080] Specifically, the production process requirements can be determined based on the AGC control performance standards, which mainly include the A / B criterion and the CPS (Control Performance Standard).
[0081] The A / B criteria include A1, A2, B1, and B2 criteria. A1 criterion: ACE must cross zero at least once every ten minutes; A2 criterion: The average ACE every ten minutes must remain within the limit of the regional load change rate. B1 criterion: ACE must return to zero within ten minutes; B2 criterion: ACE must change in a decreasing direction within one minute.
[0082] The CPS criteria include the CPS1 standard and the CPS2 standard. The CPS1 standard: Over a given period, the average one-minute ACE of the control area is equal to the average one-minute frequency deviation. The product of these factors, multiplied by ten times the frequency deviation coefficient. It should be less than the root mean square error of the one-minute average deviation between the actual annual frequency and the standard frequency. The CPS2 standard requires that the ten-minute average of ACE in the controlled area within six time periods over one hour must be controlled within the specified limits. Within.
[0083] The application process of the automatic power generation control algorithm function block is as follows:
[0084] It receives the set of operating parameters collected by SCADA from the generator set, calculates them, and outputs a set of operating control parameters.
[0085] It should be noted that the automatic generation control process can be divided into two layers. The first layer is the load distribution loop, where SCADA collects real-time operating parameters of the power grid and sends the collected parameters, such as the target total active power, actual total active power, system rated frequency, actual system frequency, upper limit of regulation, lower limit of regulation, rate of increase of regulation, rate of decrease of regulation, dead zone setpoint, and distribution mode, to the AGC algorithm software PLC system. The software PLC runs the AGC control algorithm program based on these parameters and sends the algorithm execution results, such as the power setpoint, frequency deviation ACE, and power deviation ACE, to the power plant unit power regulation device through SCADA. The second layer is the control loop of each unit, which adjusts the unit's output power to track the AGC control parameters, ultimately achieving the AGC control objective. In the entire control system, SCADA collects, stores, monitors, alarms, and forwards various parameters, while AGC, as a control link, distributes power.
[0086] The automatic power generation control algorithm function block will be updated, and there are two main ways to do so:
[0087] The first method is to update according to a preset cycle. First, it is determined whether the update time specified in the preset update cycle has been reached. When the update time is reached, it is determined whether there is updated data. If there is updated data, the update type is determined based on the updated data. Then, the updated data is processed according to the execution logic of the update type to obtain the updated automatic power generation control algorithm function block.
[0088] The second update method is mainly triggered by update data. In response to the data update instruction triggered by the update data, the update data is obtained, the update type is determined based on the update data, and the update data is processed according to the execution logic of the update type to obtain the updated automatic power generation control algorithm function block.
[0089] Optionally, the automatic power generation control algorithm function block can be invoked to process the set of operating parameters and determine the power generation type corresponding to each group of operating parameters from the set of operating parameters.
[0090] Step 103: The automatic power generation control algorithm function block executes the target algorithm program that matches the power generation type corresponding to each operating parameter group, processes the operating parameter group, and obtains the set of operating control parameters corresponding to the generator set.
[0091] Next, the automatic power generation control algorithm function block executes the target program algorithm corresponding to the power generation type matching for each group of operating parameters.
[0092] Optionally, a target algorithm program matching the power generation type of the operating parameter group can be called from the preset target algorithm program library in the automatic power generation control algorithm function block. The target algorithm program is programmed by the programmable controller software based on the automatic power generation control algorithm corresponding to different power generation types. Each target algorithm program is executed to obtain each operating control parameter group, and the operating control parameter groups are combined to form the operating control parameter set.
[0093] Specifically, the target algorithm program includes at least one built-in algorithm program, which is determined according to the preset allocation mode in the operating parameter group. The operating parameter group is then processed based on the at least one built-in algorithm program to obtain the operating control parameter group. The operating control parameter group includes, but is not limited to, power setpoint, frequency deviation ACE, and power deviation ACE.
[0094] The distribution mode is pre-configured, and its main function is to rationally and efficiently distribute the total power regulation demand to each specific generator set.
[0095] The preset allocation modes mainly include five core regional control modes: fixed system frequency control mode, fixed net exchange power control mode, fixed tie line deviation control mode, time difference correction, and unintentional exchange power compensation.
[0096] The core objective of the fixed system frequency control mode is to ensure the frequency stability and rated value of the local power grid, without considering external power exchange plans. In this mode, the ACE only reflects changes in system frequency, and the algorithm formula is as follows:
[0097] ;
[0098] in, The system frequency coefficient is (MW / 0.1Hz). , The actual frequency (Hz) The planned frequency (Hz) is used. In this mode, the power of the controlled generator sets is adjusted with reference to the system frequency coefficient to bring the system frequency to the reference value.
[0099] The core objective of the constant net switching power control mode is to strictly adhere to the contract / plan signed with the external power grid, maintaining the actual switching power consistent with the planned value, and without assuming frequency regulation responsibility. In this mode, the ACE only reflects the active power switching power of the interconnected grid, and the algorithm formula is as follows:
[0100] ;
[0101] in, , This represents the actual switching power. This mode involves planned power exchange. Based on the interconnected power exchange plan, it adjusts the power of controlled generator units to ensure the net exchange rate of the tie line reaches the planned value.
[0102] The core objective of the constant tie-line deviation control mode is to balance frequency and switching schedule compliance. This is the most commonly used and fairest control mode in interconnected power grids. The ACE (Accelerated Exchange Capacity) of this mode can simultaneously reflect changes in system frequency and the effective switching power of the interconnected power grid. The algorithm formula is as follows:
[0103] .
[0104] The core purpose of time difference correction is to correct clock errors accumulated due to long-term frequency deviation from the rated value. Specifically, this method can be used as an auxiliary correction mechanism to address the time difference between the standard clock and the electronic clock caused by accumulated frequency adjustment errors. The algorithm formula is as follows:
[0105] ;
[0106] in, The anti-locking factor is (0,1), and T is the time deviation correction coefficient (MW / Sec). This represents the deviation (Sec) between standard time and electric clock time.
[0107] The core purpose of unintentional power exchange compensation is to provide fair settlement and compensation for unplanned power exchanges caused by frequency fluctuations. Specifically, this model can serve as an auxiliary correction method to address unintentional power exchanges caused by accumulated errors in tie-line power exchange. Its algorithm formula is as follows:
[0108] ;
[0109] in, The anti-locking factor is (0,1). The repayment ratio is (0.1~1). This was an unintentional exchange of electricity.
[0110] Step 104: Send the set of operating control parameters to the generator set so that the generator set can perform the operation corresponding to the set of operating control parameters.
[0111] It should be noted that the set of operating control parameters includes the operating control parameter group corresponding to the operating parameter group. The operating control parameters include, but are not limited to, power setpoint, frequency deviation ACE, and power deviation ACE.
[0112] Finally, the set of operating control parameters is sent to the generator set to generate operating control commands for the generator set. The generator set executes the operation corresponding to the operating control commands to complete the automatic power generation control of the generator set.
[0113] For example, see Figure 3 Example diagram of input and output of the automatic power generation control algorithm function block provided in this application.
[0114] like Figure 3 As shown, the inputs of this AGC algorithm function block are the total active power target value, the total active power actual value, the system rated frequency, the system actual frequency, the adjustment upper limit AI value, the adjustment lower limit AI value, the adjustment rise rate, the adjustment fall rate, the dead zone setting value, and the allocation mode. The outputs are the power setting value, the frequency deviation ACE, and the power deviation ACE.
[0115] In summary, this application provides an AGC architecture based on SCADA distributed data acquisition and monitoring and programmability, which is a "cloud-edge-device" collaborative control architecture. It solves the defects in the structure of traditional AGC systems, effectively reuses the powerful capabilities of SCADA systems in data acquisition, monitoring, storage and analysis, and improves resource reuse rate.
[0116] Unlike traditional AGC systems that embed control algorithms in dedicated hardware or closed software, the automatic generation control algorithm function block provided in this application encapsulates the AGC algorithm into an algorithm function block using a PLC programming language. This achieves deep programmability of control logic and algorithm reuse, solving the problem of algorithm rigidity. Furthermore, this function block can be updated in a timely manner, quickly introducing advanced technologies such as artificial intelligence and model predictive control. Users can implement customized algorithms for specific scenarios, achieving regional or grid-level multi-station collaborative optimization scheduling and dynamic algorithm updates. This reduces system development difficulty and minimizes waste of manpower, material resources, and financial resources. The technology iterates promptly, has strong versatility, and a high degree of interface standardization, meeting the speed requirements of smart grid upgrades.
[0117] In summary, the automatic power generation control method provided in this application obtains a set of operating parameters for a generator set, which includes at least one set of operating parameters corresponding to a power generation type. It then calls an automatic power generation control algorithm function block to process this set of operating parameters, determines the power generation type corresponding to each set of operating parameters, controls the function block to execute a target algorithm program matching the power generation type corresponding to each set of operating parameters, processes the operating parameter sets, obtains a set of operating control parameters corresponding to the generator set, and finally sends the set of operating control parameters to the generator set. The function block in this application encapsulates various automatic power generation control algorithm programs corresponding to different power generation types. After processing by the target algorithm program, the set of operating control parameters for the generator set is obtained, thereby realizing coordinated automatic power generation control of operating parameter sets for generator sets of different power generation types.
[0118] The above describes an automatic power generation control method provided by the embodiments of this application. The following will describe the apparatus for performing the above-described automatic power generation control method.
[0119] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of the automatic power generation control device provided in this application. Figure 4 As shown, the device includes:
[0120] The system comprises an acquisition unit 10, a recall unit 20, a control unit 30, and a sending unit 40; wherein:
