Description

Technical Field

[0001] This invention relates to the field of combined heat and power (CHP) unit coordinated AIDC power supply system, specifically to a CHP unit coordinated AIDC power supply system, control method, electronic equipment and storage medium. Background Technology

[0002] As artificial intelligence data centers (AIDCs) continue to expand in scale, power supply reliability and heat dissipation requirements have become critical issues. Data centers not only need a continuous and stable power supply, but also an efficient cooling system to maintain suitable operating temperatures for chips. Traditional data centers often adopt an independent operation mode of grid power supply and electric cooling, which has problems such as strong power dependence, high cooling energy consumption, and low overall energy efficiency.

[0003] In recent years, utilizing renewable energy in conjunction with combined heat and power (CHP) to power and cool data centers has become an important development direction. CHP units can simultaneously provide stable electricity and high-quality heat, driving absorption chillers to achieve combined cooling and power generation; renewable energy sources such as wind and solar power help reduce carbon emissions. However, in existing CHP-data center co-processing systems, there is a mismatch between the volatility of wind power and the regulation rate of thermal power on the power supply side, and the matching and coordinated control of heat quality between multi-grade waste heat and multi-stage absorption chillers on the cooling side has not been effectively resolved. Especially under conditions of rapid load changes, nonlinear coupling and time-delay characteristics exist between the power supply and cooling circuits, making it difficult for traditional distributed control to simultaneously and quickly track power supply and cooling capacity, easily leading to power supply fluctuations or insufficient heat dissipation in data centers.

[0004] Therefore, there is an urgent need for a control method that can enable the coordinated operation of combined heat and power units and data center power supply systems, fully considering the coordination of multi-energy power supply, the cascade utilization of multi-grade waste heat, and the dynamic characteristics of power supply-cooling coupling, so as to improve the system's response speed and anti-disturbance capability to load changes and ensure the safe and efficient operation of data centers. Summary of the Invention

[0008] The AIDC is the core load of the system, with a power input terminal and a cooling medium input terminal. Its power input terminal is connected to the power supply module, and its cooling medium input terminal is connected to the refrigeration module. The AIDC is also equipped with an exhaust heat recovery device, the output of which is connected to the waste heat recovery circuit of the refrigeration module.

[0009] The power supply module includes a wind power generation unit, an energy storage system, and a combined heat and power (CHP) unit; the wind power generation unit outputs power to the AIDC via a green electricity direct connection to provide renewable electricity; the energy storage system is used to smooth wind power fluctuations and provide rapid power support; the CHP unit, whose output end is connected to the AIDC via the power grid, is used to provide baseload power.

[0013] The above modules can be embedded in the programmable controller in hardware form or stored in the computer memory in software form, so that the controller can call and execute the corresponding operations of the above modules.

[0014] Furthermore, this invention also proposes a control method for a combined heat and power (CHP) unit coordinated with an AIDC power supply system, specifically including the following steps:

[0016] S2: Power supply side coordination control. The power supply side power balance satisfies the following relationship:

[0017]

[0018] Among them, P wind Real-time wind power output (MW); P ees Energy storage system charging and discharging power (discharging is positive, charging is negative) (MW); P cfpp Grid-connected power of thermal power units (MW); P load AIDC real-time electricity load demand (MW); P surplus : Surplus on-grid power (MW);

[0019] (1) If In this case, AIDC is directly supplied by wind power, and the energy storage system is charged or put into standby mode according to the SOC state, while the output of the thermal power unit is reduced to the thermoelectric feasible range.

[0020] (2) If Calculate power deficit Priority is given to replenishing the power supply through energy storage system discharge. If the energy storage discharge power is insufficient to make up for the shortfall, the output of the thermal power unit will be increased. .

[0021] The energy storage charging conditions are as follows: when the wind power exceeds the AIDC load and the energy storage SOC is below a preset lower limit, the energy storage system absorbs excess wind power for charging. The energy storage charging and discharging power limits are as follows:

[0022]

[0023] in, and These are the minimum charging power (negative value) and maximum discharging power (positive value) of the energy storage system, respectively, and their absolute values ​​are determined by the rated capacity of the energy storage converter.

[0026] in, and These are the lower and upper limits of the energy storage state of charge, respectively. Take 20%, Take 90%.

[0027] S3: Cooling-side coordinated control. Total system cooling capacity C total Calculated by the following formula:

Turn on the low-grade lithium bromide absorption chiller to recover the waste heat of the AIDC itself for cooling;

[0033] like Then, electric cooling will be activated to replenish the deficit; if In this case, priority should be given to reducing the use of electric refrigeration or reducing the input of low-grade lithium bromide.

[0034] (2) Winter mode (outdoor temperature T) amb < 15℃):

[0035] Prioritize the use of natural cooling systems, utilizing outdoor cold air or cooling towers to cool the AIDC; simultaneously monitor the natural cooling capacity (C) in real time. nat With cooling load demand C load The difference, if The lithium bromide refrigeration system will be started sequentially in the order of "low grade - single effect - double effect" until the cooling load is met. At the same time, the thermal power unit will switch to cogeneration (CHP) mode, and the extracted steam will be mainly used for external heating, except for a small amount of refrigeration.

[0036] S4: Power supply-cooling coupling feedforward coordination. When the AIDC electrical load command undergoes a step change ΔP... load At that time, the feedforward discharge power command of the energy storage system is:

[0037]

[0038] Meanwhile, the feedforward change in the opening degree of the extraction valve is:

[0039]

[0040] Where, k ff This is the preset feedforward coefficient. This feedforward action can compensate for the response delay of the cooling circuit.

[0041] (1) If the load increases, the energy storage system will immediately increase the power output and increase the opening of the extraction valve in advance according to the load change rate, so that the double-effect lithium bromide chiller can obtain the heat source in advance and avoid the lag in the response of the cold load.

[0042] (2) If the load decreases, the energy storage system absorbs excess power. The extraction valve should be closed appropriately to prevent overcooling.

[0043] The output of thermal power units is adjusted according to their ramp-up rate to avoid impacting the power grid.

[0044] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the control method described above for a combined heat and power unit coordinated with an AIDC power supply system.

[0045] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the control method described above for a combined heat and power unit coordinated with an AIDC power supply system.

[0046] Compared with the prior art, the beneficial effects of the present invention are:

[0047] (1) This invention uses a three-layer power supply control strategy of wind power priority direct supply, energy storage rapid compensation and thermal power base load support.

[0061] like Figure 2 The present invention also proposes a control method for coordinated AIDC power supply of cogeneration units, which specifically includes the following steps:

[0062] S1: Acquire system status parameters. Suppose at noon on a summer day, the flue gas temperature T is... flue =170℃, extraction steam temperature T ext =220℃, AIDC exhaust temperature T waste =55℃, outdoor ambient temperature T amb =20℃, shut off when naturally cooled.

[0063] S2: Power supply side coordination control. The power supply side power balance satisfies the following relationship:

[0064]

[0065] Among them, P wind Real-time wind power output (MW); P ees Energy storage system charging and discharging power (discharging is positive, charging is negative) (MW); P cfpp Grid-connected power of thermal power units (MW); Pload AIDC real-time electricity load demand (MW); P surplus : Surplus on-grid power (MW);

[0066] (1) If In this case, AIDC is directly supplied by wind power, and the energy storage system is charged or in standby mode according to the SOC state. The output of the thermal power unit is reduced to within the feasible range of heat and power. MW.

[0067] (2) If Calculate power deficit Priority is given to replenishing the power supply through energy storage system discharge. If the energy storage discharge power is insufficient to make up for the shortfall, the output of the thermal power unit will be increased. .

[0068] The energy storage charging conditions are as follows: when the wind power exceeds the AIDC load and the energy storage SOC is below a preset lower limit, the energy storage system absorbs excess wind power for charging. The energy storage charging and discharging power limits are as follows:

[0069]

[0070] The permissible range of the State of Charge (SOC) of energy storage is:

[0071]

[0072] It is known that the initial state satisfies the power supply balance formula; assuming At that moment, the AIDC electrical load jumped from 600MW to 750MW; at this time, the energy storage system immediately discharged at its maximum power. MW response, discharge power command P ees =100MW; the remaining deficit will be generated by thermal power units: thermal power units will increase their output at a ramp rate of 10 MW / s to eventually achieve balance.

[0073] S3: Cooling-side coordinated control. Total system cooling capacity C total Calculated by the following formula:

[0074]

[0075] Where η single = 0.8, η double =1.2, η low = 0.4 represents the coefficient of performance (COP) for single-effect, double-effect, and low-grade lithium bromide refrigerators, respectively; C nat For natural cooling capacity in winter; Q flue To recover heat from flue gas; Q ext Q represents the heat of extracted steam. waste To recover waste heat from AIDC.

[0076] The system adopts different control strategies based on seasonal patterns:

[0077] (1) Summer mode (outdoor temperature T) amb >15℃):

[0078] If the flue gas temperature Start the single-effect lithium bromide absorption chiller to utilize the waste heat from the flue gas of the thermal power plant for cooling; if the extraction steam temperature... Turn on the double-effect lithium bromide absorption chiller to use steam extraction from the turbine for cooling; if the AIDC exhaust temperature...

[0079] like Then, electric cooling will be activated to replenish the deficit; if In this case, priority should be given to reducing the use of electric refrigeration or reducing the input of low-grade lithium bromide.

[0080] (2) Winter mode (outdoor temperature T) amb < 15℃):

[0081] Prioritize the use of natural cooling systems, utilizing outdoor cold air or cooling towers to cool the AIDC; simultaneously monitor the natural cooling capacity (C) in real time. nat With cooling load demand C load The difference, if The lithium bromide refrigeration system will be started sequentially in the order of "low grade - single effect - double effect" until the cooling load is met. At the same time, the thermal power unit will switch to cogeneration (CHP) mode, and the extracted steam will be mainly used for external heating, except for a small amount of refrigeration.

[0082] At this time T amb = 20℃ > 15℃, which is summer mode, and will shut down due to natural cooling.

[0083] flue gas temperature Start the single-effect lithium bromide absorption chiller and set up to recover heat from the flue gas. MW, cooling capacity MW;

[0087] S4: Power supply-cooling coupling feedforward coordination. When the AIDC electrical load command undergoes a step change ΔP... load At that time, the feedforward discharge power command of the energy storage system is:

[0088]

[0089] Meanwhile, the feedforward change in the opening degree of the extraction valve is:

[0090]

[0091] Where, k ff This is the preset feedforward coefficient. This feedforward action can compensate for the response delay of the cooling circuit.

[0092] (1) If the load increases, the energy storage system will immediately increase the power output and increase the opening of the extraction valve in advance according to the load change rate, so that the double-effect lithium bromide chiller can obtain the heat source in advance and avoid the lag in the response of the cold load.

[0093] (2) If the load decreases, the energy storage system absorbs excess power. The extraction valve should be closed appropriately to prevent overcooling.

[0094] The output of thermal power units is adjusted according to their ramp-up rate to avoid impacting the power grid.

[0095] When an AIDC electrical load change ΔP is detected load When the power output is 150MW, the feedforward control gives the following instructions:

[0096] Increase the feedforward of the extraction valve opening Take k ff =0.5% / MW, then This allows the dual-effect cooling heat source to be increased ahead of schedule. Because the energy storage has been rapidly replenished, the instantaneous drop in thermal power caused by the opening of the extraction steam valve is completely compensated by the energy storage, resulting in no disturbance on the power supply side. Approximately 30 seconds later, the system enters a new steady state: both AIDC electrical and cooling loads are precisely met, the energy storage SOC gradually decreases to 50% before ceasing discharge, and the thermal power unit power remains stable.

[0097] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the control method described above for a combined heat and power unit coordinated with an AIDC power supply system.

[0098] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the control method described above for a combined heat and power unit coordinated with an AIDC power supply system.
