Description

Technical Field

[0001] This disclosure relates to the field of energy management, and more specifically, to a campus energy coupling system based on carbon balance. Background Technology

[0002] The extraction and consumption of primary energy sources often lead to high carbon emissions and low energy efficiency. This is particularly true in primary energy extraction areas such as coal mines, which generate large amounts of associated energy resources, such as coal gangue, methane, and mine water. Traditional methods of utilizing these resources are inefficient and detrimental to environmental protection. Furthermore, primary energy consumption areas, such as power plants, typically require large fuel supplies and generate significant carbon emissions during energy conversion. Traditional carbon emission optimization methods primarily focus on coal production and development, and there is still room for improvement in carbon balance and green transition. Summary of the Invention

[0004] The first area includes primary energy and associated energy, an energy harvesting system, and a first-stage energy system; the second area includes a primary energy conversion system and a second-stage energy system.

[0005] The energy acquisition system is used to collect energy from the first region; the first cascade energy system is used to generate cascade energy in the first region using the acquired associated energy.

[0006] The primary energy conversion system is used to generate a first energy from the acquired primary energy, and the second cascade energy system is used to generate cascade energy in the second region from the acquired associated energy and / or the second energy generated by the primary energy conversion system while generating the first energy.

[0007] Wherein, the first energy is used to maintain the operation of the system in the first area and the equipment in the target living area, the tiered energy in the first area and the tiered energy in the second area are the resources required by the target living area, the carbon emissions of the energy acquisition system and the primary energy conversion system are higher than the carbon emissions of the target living area, and the first tiered energy system and the second tiered energy system achieve carbon emission reduction during operation.

[0008] In the above technical solution, resource consumption in the first and second regions is coupled. Specifically, the energy acquisition system in the first region is used to collect energy from the first region; the first-stage energy system in the first region is used to generate secondary energy from the acquired associated energy; and the primary energy conversion system in the second region is used to generate primary energy from the acquired primary energy. The second-stage energy system in the second region is used to generate secondary energy from the acquired associated energy, and / or, the secondary energy generated by the primary energy conversion system while generating primary energy. Both the first and second-stage energy systems achieve carbon emission reduction during operation. This helps achieve carbon balance, improves resource utilization within the park, and facilitates the green transformation of the park's extraction and consumption.

The secondary energy from the first and second zones can be used as resources for the target living area. In other words, associated energy or byproducts generated during energy conversion can be further utilized to achieve resource recycling.

[0009] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0014] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0015] Figure 1This is a block diagram of a carbon budget balance-based energy coupling system for a campus provided in an exemplary embodiment of this disclosure. Figure 1 As shown, the park includes a first area 10 and a second area 20. The first area 10 includes primary energy and associated energy, an energy acquisition system 101 and a first-stage energy system 102. The second area 20 includes a primary energy conversion system 201 and a second-stage energy system 202.

[0016] Energy harvesting system 101 is used to harvest energy in the first area 10;

[0017] The first-stage energy system 102 is used to generate secondary energy in the first region by utilizing the acquired associated energy.

[0018] Primary energy conversion system 201 is used to generate primary energy from the acquired primary energy.

[0019] The second-stage energy system 202 is used to generate secondary energy in the second region by utilizing the acquired associated energy and / or the second energy generated by the primary energy conversion system while generating the first energy.

[0020] The first energy is used to maintain the operation of the system in the first area 10 and the equipment in the target living area 30. The tiered energy of the first area and the tiered energy of the second area are the resources required by the target living area 30. The carbon emissions of the energy acquisition system 101 and the primary energy conversion system 201 are higher than the carbon emissions of the target living area 30. The first tiered energy system 102 and the second tiered energy system 202 achieve carbon emission reduction during operation.

[0021] For example, primary energy can be coal, and associated energy can include, but is not limited to, resources such as heat, water, gas, and cooling. Primary energy can be provided to the second region 20 as fuel for production in the second region 20. The first-stage energy system 102 can utilize the acquired associated energy to generate secondary energy for the first region. The primary energy (such as electricity) produced by the second region 20 using primary energy can provide stable production energy for the first region 10. Furthermore, the primary energy conversion system 201 can generate secondary energy while consuming primary energy; this secondary energy can be secondary energy. The secondary energy system 202 of the second region can utilize associated energy, and / or, the secondary energy generated by the primary energy conversion system while generating primary energy, can generate secondary energy for the second region. Both the first region 10 and the second region 20 are equipped with energy cascade utilization equipment, thus achieving multi-level energy utilization and significantly improving overall energy utilization efficiency. Cascade energy can include resources such as electricity, heat, water, and cooling.

[0022] By utilizing associated energy sources, the energy acquisition system 101 can achieve a certain degree of carbon emission reduction on the basis of high carbon emissions.

[0023] The primary energy source is used to maintain the operation of the system within the first zone 10 and the equipment within the target living area 30, enhancing the system's self-sufficiency, reducing dependence on external factors, and improving the system's stability and reliability. The secondary energy sources in the first and second zones can be used as resources for the target living area 30, meaning that associated energy or byproducts generated during energy conversion can be further utilized, achieving resource recycling.

[0024] In the above technical solution, resource consumption in the first and second regions is coupled. Specifically, the energy harvesting system in the first region is used to collect energy from the first region; the first-stage energy system in the first region is used to generate secondary energy from the harvested associated energy; and the primary energy conversion system in the second region is used to generate primary energy from the harvested primary energy. The second-stage energy system in the second region is used to generate secondary energy from the second region by utilizing the harvested associated energy and / or the secondary energy generated simultaneously by the primary energy conversion system and the primary energy. Both the first and second-stage energy systems achieve carbon emission reduction during operation. This approach helps achieve carbon balance, improves resource utilization within the park, and facilitates the green transformation of the park's mining and consumption processes, meeting the requirements of environmental protection and sustainable development.

[0025] In an optional embodiment, the first area can be a mining area, and the second area can be a mine-mouth power plant. The energy harvesting system can employ a circulating fluidized bed combined with a steam turbine unit to harvest primary energy.

[0026] In an optional embodiment, the associated energy includes water resources, the first-stage energy system includes a water source heat pump, the energy harvesting system includes a water pump, and the tiered energy of the first area is thermal energy of different grades.

[0027] The acquired associated energy is used to generate secondary energy in the first region, including:

[0028] Different grades of heat energy are obtained by using water resources provided by water pumps.

[0029] For example, a water source heat pump can utilize water resources provided by a water pump to obtain heat energy of different grades.

[0030] In an optional embodiment, the first region may further include at least one of a first refrigeration device, a first heating device, and a wastewater treatment device;

[0031] The first heating device is connected to a water source heat pump and is used to heat the first quality heat energy provided by the water source heat pump to obtain the first target quality heat energy.

[0032] The first refrigeration equipment is connected to a water source heat pump to cool the second-quality heat energy provided by the water source heat pump to obtain the second target-quality heat energy, which is the cooling flow required by the target living area.

[0033] Wastewater treatment equipment is connected to a water source heat pump to treat the water output from the water source heat pump in order to obtain the water resources needed by the target residential area.

[0034] For example, water source heat pumps offer advantages such as high efficiency, low cost, safety, reliability, and flexible adjustment. Mine water inflow serves as the primary water resource for the first area. Using mine water as the heat source and cold source for a water source heat pump allows heat from the living environment to be transferred into the water for cooling, and low-grade heat energy from the water to be extracted and converted into high-grade heat energy to supply the heating space, achieving a heating effect. The temperature and discharge volume of mine water are relatively stable throughout the year, with the water temperature remaining consistently around 15℃, making it an ideal heat source and cold source for water source heat pumps. The primary cooling equipment mainly consists of two types: absorption chillers and electric chillers. After wastewater treatment, the mine water, processed by the water source heat pump, can be supplied to the first area, the second area, and the target living area.

[0035] In an optional embodiment, the thermal energy of the first target taste includes the thermal energy of the third target taste and the thermal energy of the fourth target taste;

[0036] If the primary energy conversion system includes a steam turbine, the thermal energy of the third target quality is the energy input to the steam turbine; the thermal energy of the fourth target quality is the thermal energy required by the target living area.

[0037] In this way, energy can be utilized multiple times. For example, high and medium temperature heat energy (heat energy of the third target quality) can be preferentially used for power generation, while low temperature waste heat (heat energy of the fourth target quality) can be used for preheating or heating residential buildings. The quality of energy can be measured by the amount of mechanical work it can be converted into. The quality of heat energy is lower than that of mechanical energy and electrical energy, and the quality of low temperature heat energy is lower than that of high temperature heat energy.

[0038] In an optional embodiment, the primary energy source is coal; the first energy source is electrical energy, the second energy source is thermal energy, and the primary energy conversion system includes a steam turbine and a first generator;

[0039] Utilizing acquired primary energy to generate first energy includes:

[0040] The steam turbine is used to obtain mechanical and thermal energy from coal, and the first generator is used to convert the mechanical energy output by the steam turbine into electrical energy.

[0041] In an optional embodiment, the associated energy source includes gas; the primary energy conversion system further includes a gas turbine and a second generator;

[0042] The gas turbine is used to obtain mechanical and thermal energy from gas, and the second generator is used to convert the mechanical energy output by the gas turbine into electrical energy;

[0043] Steam turbines are also used to obtain mechanical and thermal energy from gas.

[0044] For example, an energy harvesting system may include a gas extraction pump that extracts high-concentration methane and transports it via pipeline to a power plant for use in gas turbine and steam turbine power generation. Carbon emission reduction can be achieved through the harvesting and utilization of methane.

[0045] In an optional embodiment, the tiered energy of the second region is thermal energy of different grades, and the second tiered energy system includes a second heating device and a second cooling device;

[0046] The second heating device is connected to the primary energy conversion system to obtain heat energy of different qualities using the heat energy output by the primary energy conversion system; the heat energy output by the second heating device includes the heat energy required by the target living area and the heat energy input to the second cooling device.

[0047] The second refrigeration unit is connected to the second heating unit to cool the input heat energy and output the required cooling flow for the target living area.

[0048] For example, the waste heat generated during the power generation process can be converted into the heat energy required by the target living area through a second heating device, and further, the required cooling flow for the target living area can be provided through a second cooling device. The second heating device can be a waste heat boiler, and the second cooling device can be an absorption chiller. Both the second heating device and the second cooling device are energy cascade utilization devices.

[0049] If the first region can be a mining area and the second region can be a mine-mouth power plant, the energy coupling process between the two regions can be as follows: Figure 2 As shown. Figure 2 Solid arrows represent the flow of electricity, double solid arrows represent the flow of heat, dashed arrows represent the flow of water resources, single dotted-dash lines represent the flow of cold energy, and double dotted-dash lines represent the flow of materials, which may include coal and gas.

[0050] The project involves the comprehensive utilization of coal gangue, gas, and water generated during mining operations. Equipment involved includes mining equipment, gas extraction pumps, water pumps, water source heat pumps for heating, thermal storage tanks, and wastewater treatment equipment. The mining area is also coupled with a pithead power plant, whose equipment includes generators, steam turbines, gas turbines, waste heat boilers, and absorption chillers.

[0051] In its production and operation, the mining area achieves comprehensive energy utilization by optimizing the allocation of heat, water, and gas resources. The coal-fired power plant supplies a stable and low-cost source of coal to the power plant, providing fuel for power generation. Water generated during coal mining is treated and used as production water for the power plant. Gas and excess heat generated can be stored in thermal storage devices or sent to the power plant. The power plant then sends waste heat steam from power generation back to the mining area for production and domestic heating. The power plant provides direct power to the mining area, providing power for coal mining operations, and also utilizes coal mine gas to generate electricity using gas turbines.

[0052] Specifically, after coal mining, washing, and preparation, the coal in the mining area is transported to a power plant for fuel, where it is used to generate electricity via steam turbines or gas turbines. For the high concentration of coalbed methane, gas extraction is performed, and mature gas power generation technologies such as gas turbine and steam turbine power generation are used to directly supply electricity to the mining area's production and residential loads. Waste heat generated during power generation can be supplied to users through waste heat boilers or used to cool the system through absorption chillers. Mine water source heat pumps offer advantages such as high efficiency, low cost, safety, reliability, and flexible adjustment. Using mine water as the heat source and cold source, heat from the living environment is transferred to the water source for cooling, while low-grade heat energy from the water source is extracted and converted into high-grade heat energy to supply heating spaces, achieving a warming effect. Additionally, wastewater treatment can provide a water source for the mining area's residential loads.

[0053] In an optional embodiment, the first area also includes a renewable energy power system and an energy storage system.

[0054] Renewable energy power systems and energy storage systems can also achieve carbon reduction during operation.

[0055] In one embodiment, the renewable energy power system is built on a primary energy waste area and / or a collapsed area filled with a filler material obtained from solid waste.

[0056] Every year, a large amount of solid waste needs to be disposed of in the mining area. The dumping of solid waste occupies a large amount of state-owned wasteland and the treatment cost is high. Therefore, using solid waste as filling material to form a high-strength filling body in the mining area and filling the abandoned mine and subsidence area can reduce the amount of compression and ensure the surface geological structure.

[0057] In this way, by utilizing the abandoned primary energy collection areas in the first region to configure renewable energy and energy storage systems, carbon balance optimization can be achieved through carbon capture and renewable energy power generation. In other words, not only can abandoned land be utilized, but green electricity can also be provided to the first region to reduce carbon emissions.

[0058] In one embodiment, the first energy is electrical energy, and the energy storage system is a system for storing and releasing electrical energy.

[0059] Thus, by adding an energy storage system, it is possible to stabilize the power output of the power system, provide backup power, improve energy utilization efficiency, regulate grid parameters, and support the grid connection of renewable energy.

[0060] In one embodiment, the renewable energy power system is a photovoltaic system.

[0061] Therefore, utilizing mining subsidence areas for photovoltaic (PV) construction, combining PV power generation with mine ecological restoration, can improve the effective use of land resources and play a positive role in ecological environment governance. Constructing PV and other green energy sources on the surface of the transformed mining area forms a green development model, while simultaneously reducing overall carbon emissions from the mine, thus facilitating the secondary use of land.

[0062] Figure 3 This is a schematic diagram of an energy coupling system between a mining area and a pithead power plant, provided in an exemplary embodiment of this disclosure. In this way, renewable energy can be configured in abandoned areas after primary energy extraction within the first area. Relying on the network transmission of materials, energy, and electricity between the first and second areas, a carbon budget design process and balance model can be established, effectively improving resource utilization within the park, reducing carbon emissions, and contributing to the green transformation of the park's mining and consumption processes.

[0063] In an optional embodiment, the photovoltaic system includes a controller.

[0064] The controller is used to determine the energy storage capacity configuration value of the photovoltaic system in the following ways:

[0065] Based on the objective function constructed with the goal of minimizing input costs, the energy storage capacity configuration value under different preset scenarios is determined through optimization algorithms.

[0066] The objective function is:

[0067] f cost =min[C invest +C OM +α*E]

[0068] Among them, f cost To invest costs, C invest For system installation costs, C OMThe system maintenance cost is represented by α, the carbon emission penalty coefficient is represented by E, and the carbon emission amount is represented by E. C OM =C OM_PV *P PV +C OM_bat *E bat C ini_PV P represents the investment cost per unit capacity of photovoltaic power. PV For real-time photovoltaic power, C ini_bat Investment cost per unit capacity of energy storage, E bat C is the configuration value for energy storage capacity. OM_PV Maintenance cost per unit capacity of photovoltaic power, C OM_bat The maintenance cost per unit capacity of energy storage. Carbon emissions E can be determined using the following formula:

[0069]

[0070] Among them, E 燃烧 CO2 emissions from the combustion of fossil fuels (in tons of CO2) This refers to the CH4 escape emissions from underground coal mines (unit: tCO2e). This refers to the CO2 escape emissions from underground coal mines (in tons of CO2). E represents the amount of CH4 recovered (in tCO2e). 自燃 E represents the CO2 emissions (tCO2) from spontaneous combustion of coal, coal gangue, and waste piles. 土地用途改变 E represents the difference in carbon sequestration capacity of land and vegetation before and after coal mining (in tons of CO2). 购入电 The CO2 emissions (in tons of CO2) corresponding to the purchased electricity are determined by the power plant's capacity. 购入电 The value.

[0071] The constraints of the objective function include at least one of the following: capacity constraints, power supply constraints, and operational constraints.

[0072] For example, the capacity constraint is:

[0073] E batL =10%*E 光伏MAX E MAX =E batL

[0074] E batXL =2.5*E batL E MAX =E batXL

[0075] E batXXL =5*E batL E MAX =EbatXXL

[0076] Among them, E batL For small-capacity energy storage, E batXL For medium-capacity energy storage, E batXXL For large-capacity energy storage, E 光伏MAX This refers to the maximum installed capacity of photovoltaic (PV) systems. For example, the maximum installed PV capacity E can be determined based on the available area. 光伏MAX Different sizes of energy storage capacity correspond to different preset scenarios.

[0077] For example, the power supply constraint is:

[0078] P PV ≤P PV_mppt

[0079] P g =P PV +P h +P bat

[0080] Among them, P PV_mppt P represents the maximum output power of the photovoltaic system. g P is the preset total electrical load. h P represents the real-time power output of the power plant. bat This represents the real-time power of the energy storage system.

[0081] Historical power output data consistent with the climatic conditions of the mining area can be used to obtain the typical daily power output characteristics in different seasons through data processing and analysis, which can be used as the maximum photovoltaic output power P in different seasons. PV_mppt The settings provide data support.

[0082] For example, the execution constraints are:

[0083] 0≤E bat ≤E MAX

[0084] P bat ≤P bates

[0085] SOC min ≤SOC t ≤SOC max

[0086]

[0087] Among them, P bates The maximum charge / discharge power of the energy storage is given by i, where i is the calculation period and its value ranges from 1 to N, and SOC is the maximum charge / discharge power. m =SOC max -SOC min SOC0 is the initial operating state of the energy storage system, P bat(i) represents the energy storage operating power in the i-th time period, and η(i) represents the energy storage operating efficiency in the i-th time period.

[0088] This disclosure, in addition to considering operation and maintenance and investment, adds carbon emission penalty fees. By taking into account carbon emission factors and different scenarios, it calculates the investment cost of photovoltaic power plants, and then determines the configuration of photovoltaic power plants and energy storage. Thus, with the goal of minimizing the carbon budget cost, renewable energy, and energy storage investment and operation and maintenance costs in the first region, and under the constraints of three energy storage capacity configurations, it calculates the optimal energy storage capacity configuration, which can achieve resource matching and utilization in a carbon budget balance mode.
