This application does not limit this.
[0049] The present application provides a method for assessing carbon emissions of a photovoltaic system, comprising: obtaining construction information of the photovoltaic system in a construction phase, and estimating a first carbon emission corresponding to the photovoltaic system in the construction phase based on the equipment information; determining operating equipment of the photovoltaic system in an operating phase, and estimating a second carbon emission corresponding to the photovoltaic system in the operating phase based on the average annual power consumption corresponding to the operating equipment; determining exit project information of the photovoltaic system in an exit phase, and estimating a third carbon emission corresponding to the photovoltaic system in the exit phase based on the exit project information; and assessing the total carbon emissions of the photovoltaic system over a full cycle based on the first carbon emissions, the second carbon emissions, and the third carbon emissions.
[0050] See also Figure 1 , Figure 1 A schematic diagram of the process flow of the photovoltaic system carbon emission assessment method provided in this application. The specific process flow of the photovoltaic system carbon emission assessment method can be as follows:
[0051] 101. Obtain construction information of the photovoltaic system during the construction phase, and estimate the first carbon emissions corresponding to the photovoltaic system during the construction phase based on the equipment information.
[0052] The construction phase is the starting stage in the life cycle of a photovoltaic power generation system, and involves multiple links, including site selection and capacity determination, site preparation, equipment delivery, installation and commissioning, etc. Site selection and capacity determination phase: determine the geographical location and scale of the photovoltaic power station, and conduct preliminary work such as planning demonstration, application confirmation and scheme design; Site preparation phase: carry out earth excavation, construction material transportation, foundation preparation and road network hardening, etc., involving the use of engineering equipment; Equipment delivery phase: transport photovoltaic modules and other auxiliary tooling and other equipment to the construction site, involving the use of transportation tools; Installation and commissioning phase: install photovoltaic modules and auxiliary equipment, and debug to ensure the normal operation of the system. Therefore, the first carbon emissions corresponding to the photovoltaic system in the construction phase can be estimated based on the personnel and equipment that enter the site during the construction phase. That is, optionally, in some embodiments of the present application, the step of "estimating the first carbon emissions corresponding to the photovoltaic system in the construction phase based on the construction information" can specifically include:
[0053] Obtain on-site personnel and equipment from construction information;
[0054] Based on the personnel and equipment entering the site, the first carbon emissions corresponding to the photovoltaic system during the construction phase are estimated.
[0055] Specifically, the working time involved in the site selection and capacity determination link is converted into equivalent working hours for calculating carbon emissions. At the same time, the corresponding equivalent power consumption is calculated based on the rated output power, operating time and fuel consumption of the engineering equipment and transportation tools used in each link. Then, based on the equivalent working hours and the power consumption corresponding to the on-site equipment, the first carbon emissions corresponding to the photovoltaic system in the construction stage are estimated. That is, optionally, in some embodiments of the present application, the step of "estimating the first carbon emissions corresponding to the photovoltaic system in the construction stage based on the on-site personnel and on-site equipment" may specifically include:
[0056] Calculate the equivalent working hours corresponding to the personnel entering the site;
[0057] Calculating, based on a first preset formula, a first power consumption corresponding to the site preparation phase of the on-site equipment during the construction phase;
[0058] Calculating, based on a second preset formula, a second power consumption corresponding to the equipment entering the site during the construction phase;
[0059] Calculating, based on a third preset formula, a third power consumption corresponding to the installation and debugging phase of the on-site equipment during the construction phase;
[0060] The first carbon emissions corresponding to the photovoltaic system during the construction phase are estimated based on the equivalent working hours, the first power consumption, the second power consumption and the third power consumption.
[0061] It should be noted that equivalent working hours are also called equivalent man-years (Man-Years, MY). Equivalent man-years (MY) is a unit used to measure workload or labor input, which represents the amount of work a person does in one year. In the construction phase of a photovoltaic power generation system, equivalent man-years are used to estimate the contribution of manpower input to carbon emissions. Specifically, it can be expressed as follows: t1 (man-year) = total man-days corresponding to travel / meetings × 7 / (5×360). For example, if a project has a total of 100 people participating in the site selection and capacity determination phase, and each person participates for 10 days, then the total man-days is 1000 man-days. Substituting this value into the above formula, we get equivalent man-years t1 = 1000 / 5x360 = 0.56 man-years, that is, the manpower input of this project in the site selection and capacity determination phase is equivalent to 0.56 people working for one year. This value will then be used to calculate carbon emissions during the construction phase.
[0062] Among them, for the site preparation link, first of all, it is necessary to determine all the engineering equipment used in the site preparation link, such as excavators, bulldozers, trucks, etc. Then, collect the rated output power and operating time of each device. Next, calculate the power consumption of a single device: for each device, use the following formula to calculate its power consumption in the site preparation link, the power consumption of a single device = rated output power × operating time, and finally, according to the first preset formula, calculate the equivalent power consumption of all on-site equipment as W11, W11 = 1.15 × (rated output power of device 1 × operating time of device 1 + ... rated output power of device n × operating time of device n). In addition, for the equivalent power consumption W12 involved in the removal of construction waste, transportation of construction materials, etc., W12 = removal tonnage × removal mileage × average fuel consumption per kilometer + transportation tonnage × transportation mileage × average fuel consumption per kilometer, thereby obtaining the first power consumption corresponding to the site preparation link in the construction phase.
[0063] For the equipment entry stage, the equivalent power consumption involved in the transportation of photovoltaic components, auxiliary tooling, etc. is determined as W13, W13 = equipment 1 tonnage × equipment 1 transportation mileage × average fuel consumption per kilometer + equipment 2 tonnage × equipment 2 transportation mileage × average fuel consumption per kilometer +… equipment n tonnage × equipment n transportation mileage × average fuel consumption per kilometer.
[0064] For the installation and debugging phase, the power consumption of the equipment during the installation and debugging phase is determined to be W14, where W14=1.15×(rated output power of equipment 1×operating time of equipment 1+…+rated output power of equipment n×operating time of equipment n).
[0065] 102. Based on the average annual power consumption of the operating equipment, estimate the second carbon emissions of the photovoltaic system during the operation phase.
[0066] For example, the equipment required during the operation phase of the photovoltaic system can be determined, such as cleaning equipment, monitoring systems, backup power supplies, etc. Then, collect the annual average power consumption data for each device, which may require the energy consumption specifications or historical energy consumption records of the equipment. Then, add up the annual average power consumption of all operating equipment to obtain the total power consumption during the operation phase. Finally, use the appropriate carbon emission factor to convert energy consumption into a second carbon emission.
[0067] Optionally, in some embodiments of the present application, the step of “estimating the second carbon emissions corresponding to the photovoltaic system during the operation phase based on the average annual power consumption corresponding to the operating equipment” may specifically include:
[0068] Determine the average annual power consumption for cleaning and maintenance and troubleshooting of the operating equipment;
[0069] Based on the average annual power consumption for cleaning and maintenance as well as the power consumption for troubleshooting, the second carbon emissions corresponding to the photovoltaic system during the operation phase are estimated.
[0070] Identify equipment used for cleaning photovoltaic panels, such as automatic cleaning robots or manual cleaning equipment, and collect their power consumption data. And identify equipment used for troubleshooting, such as backup power supplies, maintenance tools, etc., and collect their power consumption data. Then, collect the annual average power consumption data of cleaning and maintenance equipment and the power consumption data during troubleshooting. Finally, add the annual average power consumption of cleaning and maintenance equipment and troubleshooting equipment to obtain the total annual average power consumption during the operation phase, and convert energy consumption into carbon emissions (second carbon emissions) through the carbon emission factor.
[0071] Specifically, the power consumption of the equipment in the demolition process is defined as W31, W31 = 1.15 × (rated output power of equipment 1 × running time of equipment 1 + ... + rated output power of equipment n × running time of equipment n); the equivalent power consumption of all engineering equipment such as ditch backfilling and slope management is defined as W32, W32 = 1.15 × (rated output power of equipment 1 × running time of equipment 1 + ... + rated output power of equipment n × running time of equipment n); the equivalent power consumption involved in solid waste transfer is defined as W33, W33 = transfer tonnage × transfer mileage × average fuel consumption per kilometer. The carbon emissions in the operation stage are defined as P3, P3 = (W31 + W32 + W33) × 1.078 / λ, where λ is the conversion efficiency of the fuel-power output process of the engineering equipment, which is 0.15-0.20.
[0072] Optionally, in some embodiments of the present application, the step of “estimating the second carbon emissions corresponding to the photovoltaic system during the operation phase based on the annual average power consumption for cleaning and maintenance and the power consumption for troubleshooting” may specifically include:
[0073] Obtain multiple replacement parts and the corresponding removal and transportation losses of each replacement part;
[0074] Calculate the product of the weight of each replacement part and the corresponding removal loss to obtain the replacement loss corresponding to each replacement part;
[0075] Calculate the sum of replacement losses corresponding to all replacement parts to obtain the troubleshooting power consumption corresponding to the operating equipment.
[0076] For example, determine the parts that may need to be replaced during the operation phase, such as photovoltaic panels, inverters, junction boxes, etc., and obtain their weights. Then, the energy consumption data of each replacement part during the removal process, which may include the fuel consumption or electricity consumption of the transportation tool. Next, for each replacement part, calculate the product of its weight and the removal loss to obtain the replacement loss of the replacement part. Finally, add up the replacement losses of all replacement parts to obtain the total power consumption of the operating equipment during the troubleshooting process.
[0077] Specifically, calculate the replacement loss of a single replacement part: for replacement part A: replacement loss A = 100kg×20L / time×9.0kWh / LReplacement loss A = 100kg×20L / time×9.0kWh / LReplacement loss A = 18000kWhReplacement loss A = 18000kWh; for replacement part B: replacement loss B = 50kg×10L / time×9.0kWh / LReplacement loss B = 50kg×10L / time×9.0kWh / LReplacement loss B = 4500kWhReplacement loss B = 4500kWh.
[0078] Total replacement loss = replacement loss A + replacement loss B Total replacement loss = replacement loss A + replacement loss B Total replacement loss = 18000kWh + 4500kWh Total replacement loss = 18000kWh + 4500kWh Total replacement loss = 22500kWh Total replacement loss = 22500kWh. This is the power consumption caused by the removal of replacement parts during the troubleshooting process of the running equipment. This power consumption is the troubleshooting power consumption W23.
[0079] 103. Estimate the third carbon emissions corresponding to the photovoltaic system during the exit phase based on the exit project information.
[0080] For example, determine the engineering activities that need to be carried out when the photovoltaic system is withdrawn, including component removal, site remediation, waste disposal, etc. Then. Collect the power consumption parameters of the equipment required for the withdrawal phase, such as the rated power and working time of excavators, cranes, transport vehicles, etc. Next, for each device, calculate the power consumption based on its power and working time. In addition, if there is waste that needs to be transported, calculate the additional power consumption based on the weight of the waste, the transportation distance, and the energy consumption of the transportation tool. Finally, add the power consumption of all equipment and the power consumption of waste transportation to obtain the total power consumption in the withdrawal phase, so as to determine the third carbon emissions.
[0081] Optionally, in some embodiments of the present application, the step of “estimating the third carbon emissions corresponding to the photovoltaic system in the exit stage based on the exit project information” may specifically include:
[0082] Calculate the dismantling power consumption when performing equipment dismantling tasks in the exit phase;
[0083] Calculate the restoration power consumption when performing site restoration tasks during the exit phase;
[0084] Based on the dismantling power consumption and repair power consumption, the third carbon emissions corresponding to the photovoltaic system in the exit stage are estimated.
[0085] For example, the PV system decommissioning phase includes the following activities:
[0086] Component removal was performed using 1 excavator with a rated power of 300 kW and a working time of 50 hours.
[0087] The components were hoisted using a crane with a rated power of 150 kW and a working time of 30 hours.
[0088] Waste materials (such as damaged photovoltaic panels) need to be transported, with a total weight of 2 tons and a transportation distance of 50 kilometers, assuming a fuel consumption of 0.5 liters per kilometer.
[0089] Assuming the energy density of diesel is 10 kWh / L, the regional grid carbon emission factor is 0.9 kg CO2 / kWh.
[0090] Calculate the equipment power consumption: W31=300kW×50h=15000kWh; W32=150kW×30h=4500kWh; Calculate the waste transfer power consumption: W33=2t×50km×0.5L / km×10kWh / L=500kWh; Calculate the total power consumption: Total power consumption=W31+W32+W33=15000kWh+4500kWh+500kWh=20000kWh.
[0091] Calculation of the tertiary carbon emissions: P3 = total power consumption × carbon emission factor P3 = total power consumption × carbon emission factor = 20,000 kWh × 0.9 kg CO2 / kWh = 18,000 kg CO2, indicating that in the exit stage, the tertiary carbon emissions of the PV system are estimated to be 18,000 kg of carbon dioxide.
[0092] 104. Based on the first carbon emissions, the second carbon emissions and the third carbon emissions, evaluate the total carbon emissions of the photovoltaic system throughout its entire cycle.
[0093] For example, specifically, obtain the carbon emissions P1 in the construction phase, the carbon emissions P2 in the operation phase, and the carbon emissions P3 in the exit phase. Since the carbon emissions in the operation phase are calculated on an annual basis, it is necessary to multiply the annual carbon emissions by the life cycle of the photovoltaic system to obtain the total carbon emissions in the operation phase. Add the carbon emissions in the construction phase, the operation phase, and the exit phase to obtain the total carbon emissions for the entire cycle.
[0094] Optionally, in some embodiments of the present application, the step of “evaluating the total carbon emissions of the photovoltaic system over the entire cycle according to the first carbon emissions, the second carbon emissions, and the third carbon emissions” may specifically include:
[0095] Obtain annual carbon emission reductions;
[0096] Calculate the sum of the first carbon emission, the second carbon emission and the third carbon emission to obtain a reference total carbon emission;
[0097] The difference between the reference total carbon emissions and the annual carbon emission reduction is calculated to obtain the total carbon emissions of the photovoltaic system throughout its entire cycle.
[0098] For example, the annual carbon emission reduction PN can be calculated based on the annual power generation of the photovoltaic system and the baseline emission factor of the regional power grid. Then, the first carbon emission P1, the second carbon emission P2, and the third carbon emission P3 are added together to obtain the reference total carbon emissions over the entire life cycle. Finally, the difference between the reference total carbon emissions and the annual carbon emission reduction is calculated to obtain the total carbon emissions P of the photovoltaic system throughout its entire cycle.
[0099] The above completes the photovoltaic system carbon emission assessment process of this application.
[0100] As described above, the present application provides a method for assessing carbon emissions of a photovoltaic system, which obtains the construction information of the photovoltaic system in the construction phase, and estimates the first carbon emissions corresponding to the photovoltaic system in the construction phase based on the equipment information, determines the operating equipment of the photovoltaic system in the operation phase, and estimates the second carbon emissions corresponding to the photovoltaic system in the operation phase based on the average annual power consumption corresponding to the operating equipment, determines the exit project information of the photovoltaic system in the exit phase, and estimates the third carbon emissions corresponding to the photovoltaic system in the exit phase based on the exit project information, and finally, based on the first carbon emissions, the second carbon emissions and the third carbon emissions, the total carbon emissions of the photovoltaic system in the entire cycle are assessed. In the photovoltaic system carbon emission assessment scheme provided in the present application, first, by estimating the carbon emissions corresponding to the photovoltaic system in the construction phase, the operation phase and the exit phase, and then, based on the estimated carbon emissions, the total carbon emissions of the photovoltaic system in the entire cycle are assessed, which can effectively and directly assess the contribution of photovoltaic power station power generation to carbon reduction, and improve the rationality of the carbon emission accounting assessment results.
