Due to the increasing demand for fossil fuels, excessive emissions of greenhouse gases such as CO2 have been caused. With the intensification of global climate anomalies and warming, how to reduce greenhouse gas emissions is an important issue currently facing the international community. The influencing factors of carbon price are complex, and accurate prediction of carbon price is a difficult problem. There are still some problems in the existing carbon trading price prediction models, such as insufficient understanding of the enormous potential of machine learning models to ilift the performance. The study will use two machine learning models that can address the shortcomings of traditional artificial intelligence models as the basic prediction models. The specific content includes machine learning prediction models that extend to extreme learning machine theory and fuzzy inference system theory. By integrating data preprocessing algorithms, artificial intelligence optimization algorithms, feature selection algorithms, etc., this study constructs and applies a carbon trading price prediction model from multiple perspectives to compensate for the shortcomings in current research. The corresponding values for each indicator in the algorithm are 5.6214E-12 (maximum), 2.8546E-12 (minimum), 4.0239E-12 (mean), and 5.4402E-13 (variance). Compared with other comparative optimization algorithms, this indicates that the hybrid optimization algorithm is an efficient optimization method for the model, which can effectively optimize different problems. In theory, the proposed multiple improved carbon trading price prediction models can theoretically compensate for the shortcomings in existing carbon trading price predictions.
由于对化石燃料的需求不断增加,导致二氧化碳等温室气体排放过多。随着全球气候异常和变暖的加剧,如何减少温室气体排放是当前国际社会面临的重要问题。碳价格的影响因素复杂,准确预测碳价格是一个难题。现有的碳交易价格预测模型还存在一些问题,如对机器学习模型在提高性能方面的巨大潜力认识不足。本研究将采用两种能够解决传统人工智能模型缺陷的机器学习模型作为基本预测模型。具体内容包括扩展到极限学习机理论和模糊推理系统理论的机器学习预测模型。本研究通过整合数据预处理算法、人工智能优化算法、特征选择算法等,从多个角度构建并应用碳交易价格预测模型,弥补了当前研究的不足。算法中各指标的对应值分别为:5.6214E-12(最大值)、2.8546E-12(最小值)、4.0239E-12(均值)、5.4402E-13(方差)。与其他比较优化算法相比,这表明混合优化算法是一种高效的模型优化方法,可以有效优化不同问题。从理论上讲,所提出的多种改进的碳交易价格预测模型可以从理论上弥补现有碳交易价格预测的不足。

Energy shortages and environmental degradation are issues that are getting more and more significant globally. New energy vehicles are being promoted by the state due to the advantages of low pollution and low fuel consumption. However, due to battery technology, the range of new energy vehicles cannot meet the needs of users. As the most energy-efficient auxiliary device, the energy consumption of air conditioning will significantly reduce the range of new energy vehicles. In low temperature environments, heating energy consumption will reduce the range of vehicles by more than 50%. Therefore, the research aims to reduce the energy consumption of air conditioning systems in new energy vehicles by reducing load demand and improving operating efficiency. The study designs a low-temperature heat pump air conditioning system based on digital technology and then uses a computational algorithm to construct an energy consumption model for the heat pump air conditioning system of a new energy vehicle. According to the test results, the system’s average increase in heat production after activating the enthalpy charge is 35% and its average COP is 0.14% lower than when switched off. At -5oC, the air outlet temperature of the system reaches up to 50.0oC. Summer cooling energy consumption increases exponentially with temperature, while winter heating energy consumption decreases linearly with temperature. In addition, the range decreases significantly as the ambient temperature deviates from the human comfort zone. The decline in the winter range is more severe than that in summer, moreover, the range of modern energy vehicles is reduced by 30% at an average winter temperature of -10oC. In summary, the low-temperature heat pump system offers greater performance. It is more useful in real-world applications and can offer a rational alternative to air conditioning’s energy-saving tactics.
能源短缺和环境恶化是全球日益突出的问题。新能源汽车因其低污染、低油耗等优势,正在被国家大力推广。然而,由于电池技术的原因,新能源汽车的续航能力无法满足用户的需求。空调作为最节能的辅助设备,其能耗将大大降低新能源汽车的续航里程。在低温环境下,制热能耗将使车辆续航里程减少 50%以上。因此,该研究旨在通过降低负载需求和提高运行效率来降低新能源汽车空调系统的能耗。该研究设计了一种基于数字技术的低温热泵空调系统,然后利用计算算法构建了新能源汽车热泵空调系统的能耗模型。测试结果表明,启动焓充后,系统制热量平均增加 35%,平均 COP 比关闭时降低 0.14%。在零下 5 摄氏度时,系统的空气出口温度高达 50.0 摄氏度。夏季制冷能耗随温度呈指数增长,而冬季制热能耗则随温度呈线性下降。此外,当环境温度偏离人体舒适区时,能耗范围也会明显缩小。冬季续航里程的下降比夏季更为严重,此外,在冬季平均温度为零下 10 摄氏度时,现代能源汽车的续航里程会减少 30%。总之,低温热泵系统具有更高的性能。在实际应用中,它的作用更大,可以合理替代空调的节能策略。

Objective and effective prediction of energy consumption can not only optimize the energy consumption structure, but also provide important information for the government to formulate energy conservation and emission reduction measures. With the development of new energy sources and changes in the global energy consumption structure, historical energy data that are too old may no longer be reliable for forecasting, which leads to a decrease in the amount of information on energy, and the gray theory, which is applicable to “poor information”, has gained attention. Firstly, the optimization of energy economic objectives and transformation path methods at this stage is clarified; then, the DEA-Malmqusit model is used to improve the shortcomings of the traditional model that can only compare different cross-sections at the same time node, and to evaluate and analyze the full-factor multi-indicators of energy enterprises in terms of technological empowerment, environmental dynamics, and economic output efficiency; finally, the LEAPS-based energy system consumption and load capacity prediction model. The results show that the traditional algorithm is not accurate enough and has some deviation when the energy raw data fluctuates a lot. The algorithm proposed in this paper still gives a better prediction, predicting a city’s carbon emission to be 65,240,100 tons in 2024, with a 3.6% increase in energy output year by year.
客观有效的能源消费预测不仅可以优化能源消费结构,还可以为政府制定节能减排措施提供重要信息。随着新能源的发展和全球能源消费结构的变化,过于陈旧的能源历史数据可能不再是预测的可靠依据,这导致能源信息量的减少,适用于 "信息贫乏 "的灰色理论受到关注。首先,明确了现阶段能源经济目标的优化和转型路径方法;然后,利用DEA-Malmqusit模型改进了传统模型只能在同一时间节点对不同截面进行比较的缺点,从技术赋权、环境动态、经济产出效率等方面对能源企业进行全要素多指标评价分析;最后,提出了基于LEAPS的能源系统消费和负荷能力预测模型。结果表明,当能源原始数据波动较大时,传统算法不够准确,存在一定偏差。本文提出的算法仍然给出了较好的预测结果,预测 2024 年某市的碳排放量为 6524.01 万吨,能源产出逐年增长 3.6%。

Between 2000 and 2020, the residential sector’s share of Algeria’s final energy consumption was 62.20% and 46.05% respectively; this was much higher than the global average of 31%. This enables us to comprehend the factors that contribute to the rise in energy consumption in the residential sector and to carry out a quantitative analysis to determine the extent to which energy efficiency reduces energy consumption in the sector between 2000 and 2020. To accomplish this, we employ the decomposition analysis approach by using the Logarithmic Mean Divisia Index (LMDI). The results of the study showed that the energy subsidy factor had a strong impact on increasing residential energy consumption in Algeria, compared to the population growth factor. In addition, the energy intensity factor and the economic structure factor did not help reduce energy consumption levels. According to these findings, Algerian public policymakers should strictly implement the national energy program Horizon 2030 by rationalising energy use, eliminating subsidies gradually, and monitoring the implementation of energy efficiency measures in the residential sector.
2000 年至 2020 年期间,住宅部门在阿尔及利亚最终能源消耗中所占的份额分别为 62.20% 和 46.05%,远远高于全球 31%的平均水平。这使我们能够理解导致住宅部门能耗上升的因素,并进行定量分析,以确定在 2000 年至 2020 年期间,能源效率在多大程度上降低了住宅部门的能耗。为此,我们采用了对数平均除法指数(LMDI)分解分析方法。研究结果表明,与人口增长因素相比,能源补贴因素对阿尔及利亚居民能源消耗的增加有很大影响。此外,能源强度因素和经济结构因素无助于降低能源消耗水平。根据这些研究结果,阿尔及利亚公共政策制定者应严格执行《2030 年地平线》国家能源计划,合理使用能源,逐步取消补贴,并监督住宅部门能效措施的执行情况。

Excessive carbon emissions will lead to catastrophic consequences such as global warming and rising oceans and will also have a serious negative impact on the human food supply and living environment. The steel industry is characterized by high pollution, and about 18% of China’s carbon emissions come from the steel industry. The ‘double carbon’ strategy has brought important tasks and severe challenges to China’s steel industry. With a view to evaluating the achievements of carbon emission control, carbon emission monitoring systems at home and abroad have been continuously established and improved. For the steel industry, accurate and efficient carbon monitoring technology has a guiding role in guiding energy conservation and carbon reduction. Traditional carbon emission accounting methods have some problems, such as long cycles and poor data quality, which restrict the improvement of the lean level of carbon emission monitoring management. Firstly, this paper investigates and analyzes the productive process and carbon emission process of the steel industry and constructs an entropy weight-grey correlation -TOPSIS analysis method for the correlation between carbon emissions and influencing factors. Based on the above content, a carbon emission monitoring method based on multiple influencing factors is put forward, and the high monitoring accuracy of the model is proved by taking the Tianjin steel industry as an example. The results show that information mining of relevant data can strikingly increase the accuracy of carbon emission monitoring in the steel industry.
过量的碳排放将导致全球变暖、海洋上升等灾难性后果,也将对人类的食物供应和生活环境造成严重的负面影响。钢铁行业具有高污染的特点,中国约 18% 的碳排放来自钢铁行业。双碳 "战略给中国钢铁工业带来了重要任务和严峻挑战。为评估碳排放控制成果,国内外碳排放监测体系不断建立和完善。对于钢铁行业来说,准确、高效的碳监测技术对节能减碳具有指导作用。传统的碳排放核算方法存在周期长、数据质量差等问题,制约了碳排放监测管理精益化水平的提高。本文首先对钢铁行业的生产过程和碳排放过程进行了调查分析,并构建了碳排放与影响因素相关性的熵权-灰色关联-TOPSIS分析方法。在上述内容的基础上,提出了一种基于多影响因素的碳排放监测方法,并以天津钢铁行业为例,证明了该模型具有较高的监测精度。结果表明,对相关数据进行信息挖掘可以显著提高钢铁行业碳排放监测的准确性。

In India, the adoption of sustainable and efficient renewable energy systems has become imperative for achieving sustainable development. Nowadays in India about 60% of the population has access to grid power, but due to the unreliable nature of electricity users, it is still necessary to rely on biofuels such as solar and animal waste for everyday activities like heating and cooking. With over 370 million tons of biomass produced annually in India, there is a significant market opportunity for biomass boilers in the country. This research paper proposes a hybrid system comprising of solar, and biomass from an end-user perspective. The proposed hybrid system has been modelled and analyzed using multisim software. Furthermore, the study assesses the feasibility of the proposed low-cost hybrid power system blueprint for the outlying regions of Baheya village, Ranchi, India, by utilizing the Multi-Criteria Decision Making (MCDM) technique. It has been observed that the total per unit cost of a hybrid system, which is Rs. 1.76, is lower compared to the individual per unit costs of solar and biomass plants, which are Rs. 1.628 and Rs. 0.433, respectively. The analysis shows that the proposed hybrid system is a reliable solution for providing electricity in the Baheya village.
在印度,采用可持续和高效的可再生能源系统已成为实现可持续发展的当务之急。目前,印度约有 60% 的人口可以使用电网供电,但由于电力用户的不稳定性,取暖和做饭等日常活动仍需依靠太阳能和动物粪便等生物燃料。印度每年生产的生物质超过 3.7 亿吨,因此生物质锅炉在印度有很大的市场机会。本研究论文从最终用户的角度出发,提出了一种由太阳能和生物质能组成的混合系统。本文使用 multisim 软件对所提出的混合系统进行了建模和分析。此外,研究还利用多标准决策(MCDM)技术评估了印度兰契巴希亚村外围地区拟议的低成本混合动力系统蓝图的可行性。结果表明,混合系统的单位总成本为 1.76 卢比,低于太阳能发电厂和生物质发电厂的单位成本(分别为 1.628 卢比和 0.433 卢比)。分析表明,拟议的混合系统是为 Baheya 村提供电力的可靠解决方案。

Study on the Annual Runoff Forecast Model of the Main Stream of Nanxi River Based on PSO-ANFIS 基于 PSO-ANFIS 的楠溪江干流年径流预报模型研究

In 2021, Wenzhou adopted measures to restrict the use of electricity, and the shortage of electricity became an important factor affecting the production and life of Wenzhou. Nanxi River is one of the main rivers in Wenzhou City, and its water resources are very rich. According to the statistics of the water conservancy planning of the Nanxi River basin, there are 96 hydropower stations in the Nanxi River basin, with a total installed capacity of 152100 kW, accounting for 57% of the installed capacity. The development and utilization of the Nanxi River water resources can alleviate the power shortage in Wenzhou power grid to a certain extent. The development and utilization of hydropower are closely related to the runoff of the basin. The river runoff is mainly determined by rainfall, underlying surface and upstream inflow. River runoff is affected by many factors in the process of formation, so it is difficult to improve its prediction accuracy. In order to improve the prediction accuracy of the runoff of the main stream of the Nanxi River, this paper introduces the runoff prediction model of particle swarm optimization adaptive fuzzy inference system (PSO-ANFIS). ANFIS model has the advantages of applying fuzzy rules and the nonlinear approximation ability of neural network, but the antecedent parameters of ANFIS model are prone to fall into local optimization. In order to improve the generalization ability of the antecedent parameters of ANFIS model, the PSO algorithm of global optimization is introduced to optimize the antecedent parameters of ANFIS. Through the application of the example, it is found that the decision coefficient of PSO-ANFIS model in the simulation stage is 0.987, and the decision coefficient in the prediction stage is 0.856. This model can be applied in the annual runoff forecast. Through comparison with ANFIS model, it is found that PSO-ANFIS model has better prediction effect.
2021 年,温州采取限电措施,电力短缺成为影响温州生产生活的重要因素。楠溪江是温州市的主要河流之一,水资源十分丰富。据楠溪江流域水利规划统计,楠溪江流域共有水电站 96 座,总装机容量 152100 千瓦,占装机容量的 57%。楠溪江水资源的开发利用,可在一定程度上缓解温州电网缺电问题。水电的开发利用与流域径流密切相关。江河径流主要由降雨、下垫面和上游来水决定。河流径流在形成过程中受多种因素影响,因此很难提高其预测精度。为了提高楠溪江干流径流的预测精度,本文引入了粒子群优化自适应模糊推理系统(PSO-ANFIS)的径流预测模型。ANFIS模型具有应用模糊规则和神经网络非线性逼近能力的优点,但ANFIS模型的前置参数容易陷入局部优化。为了提高 ANFIS 模型前置参数的泛化能力,引入了全局优化的 PSO 算法来优化 ANFIS 的前置参数。通过实例应用发现,PSO-ANFIS 模型在模拟阶段的决策系数为 0.987,在预测阶段的决策系数为 0.856。该模型可用于年径流预报。通过与 ANFIS 模型比较,发现 PSO-ANFIS 模型具有更好的预测效果。

Nanxi River is one of the main rivers in Wenzhou City, and its water resources are very rich. According to the statistics of the water conservancy planning of the Nanxi River basin, there are 96 hydropower stations in the Nanxi River basin, with a total installed capacity of 152100 kW, accounting for 57% of the installed capacity. The development and utilization of the Nanxi River water resources can alleviate the power shortage in Wenzhou power grid to a certain extent. The development and utilization of hydropower are closely related to the runoff of the basin. The river runoff is mainly determined by rainfall, underlying surface and upstream inflow. River runoff is affected by many factors in the process of formation, so it is difficult to improve its prediction accuracy. In order to improve the prediction accuracy of the runoff of the main stream of the Nanxi River, this paper introduces the runoff prediction model of particle swarm optimization adaptive fuzzy inference system (PSO-ANFIS). ANFIS model has the advantages of applying fuzzy rules and the nonlinear approximation ability of neural network, but the antecedent parameters of ANFIS model are prone to fall into local optimization. In order to improve the generalization ability of the antecedent parameters of ANFIS model, the PSO algorithm of global optimization is introduced to optimize the antecedent parameters of ANFIS.

Climate change is one of the major challenges currently facing the world. The factors influencing the carbon emission of energy consumption and the future trend are important guidance for proposing scientific carbon reduction strategies to mitigate climate change. In this paper, the Logarithmic Mean Divisia Index (LMDI) model and stochastic impacts by regression population, affluence and technology (STIRPAT) model are established to analyze and predict the carbon emission of energy consumption. The LMDI model is used to factorize the CO2 changes generated by residential domestic energy consumption, and to decompose and analyze the carbon emission factors of residential domestic energy consumption in terms of energy carbon emission intensity, energy consumption structure, energy consumption intensity, economic development, and population to determine the driving factors leading to carbon emission changes; based on the above study, we set up nine different development scenarios and applied the scalable stochastic environmental impact assessment model to project energy carbon emissions in 2035; based on carbon emission prediction and analysis, the CO2 emissions of total energy consumption, total electricity consumption, industrial energy consumption and terminal energy consumption were selected, and the correlation coefficients with relevant climate indicators such as temperature change and humidity change were analyzed, and the stress model of energy consumption on climate change was constructed. The results show that: the correlation coefficients of energy consumption indicators and temperature change indicators all pass the significance test at P = 0.01 level, among which the correlation coefficients with temperature difference are the highest, all of them are greater than 0.9 and pass the significance test at P = 0.001 level; among the indicators of energy consumption, the correlation coefficient between total industrial energy consumption and temperature difference was slightly higher than that of total energy consumption and electricity consumption; the stress relationship between the increase of energy consumption and the temperature difference is consistent with the growth of the third polynomial curve.
气候变化是当前世界面临的重大挑战之一。能源消耗碳排放的影响因素及未来趋势对提出科学的碳减排策略以减缓气候变化具有重要指导意义。本文建立了对数平均指数(LMDI)模型和回归人口、富裕程度和技术的随机影响(STIRPAT)模型来分析和预测能源消耗的碳排放。利用 LMDI 模型对居民生活能源消费产生的二氧化碳变化进行因子化,从能源碳排放强度、能源消费结构、能源消费强度、经济发展、人口等方面对居民生活能源消费的碳排放因子进行分解分析,确定导致碳排放变化的驱动因素;在上述研究的基础上,设定九种不同的发展情景,应用可扩展的随机环境影响评估模型对 2035 年的能源碳排放进行预测;在碳排放预测分析的基础上,选取能源消费总量、电力消费总量、工业能源消费总量和终端能源消费总量的二氧化碳排放量,分析其与气温变化、湿度变化等相关气候指标的相关系数,构建能源消费对气候变化的压力模型。结果表明:能耗指标与温度变化指标的相关系数均在 P = 0.01 水平上通过显著性检验,其中与温差的相关系数最高,均大于 0.9,且在 P = 0.001 水平下通过显著性检验;在能耗指标中,工业总能耗与温差的相关系数略高于总能耗与电耗的相关系数;能耗增加与温差的应力关系符合三次多项式曲线的增长关系。

In order to investigate the effect of different substrates of constructed wetlands on the purification of polluted water in rivers and their greenhouse gas emissions, this study designed three small-scale constructed wetland experimental systems with traditional gravel (CW-G), volcanic rock (CW-V) and biomass carbon (CW-B) as filler substrates to investigate the effect of different constructed wetland systems on the removal of COD and nitrogen pollutants and to further analyse their effect on greenhouse gas emissions. The results showed that the removal rates of organic matter in all three groups of constructed wetlands reached over 90%. and 49.29% to 58.71%, respectively, with CW-V and CW-B significantly improving the removal of NH4 + -N and NO3− -N compared to CW-G (P < 0.05). A comparison of greenhouse gas emissions reveals that although CW-B resulted in the highest N2O emissions due to its better removal of NO3− -N, its share in nitrogen removal was still the smallest. In addition, the rapid consumption of organic matter in the influent water and the oxidation of some CH4 to CO2 resulted in no detectable CH4 in any of the three groups of constructed wetlands. The results of this study show that the differences in treatment effects and greenhouse gas emissions between the three types of substrate constructed wetlands are significant, and this study can provide some scientific reference for the construction and operation of wetlands for the purification of polluted water bodies in rivers.
为探讨不同基质的构建湿地对河流污染水体净化及其温室气体排放的影响,本研究设计了以传统砾石(CW-G)、火山岩(CW-V)和生物质碳(CW-B)为填充基质的三组小型构建湿地实验系统,考察不同构建湿地系统对COD和氮污染物的去除效果,并进一步分析其对温室气体排放的影响。结果表明,三组构建湿地对有机物的去除率均达到 90% 以上,CW-V 和 CW-B 对 NH4 + -N 和 NO3- -N 的去除率分别为 49.29% 至 58.71%,与 CW-G 相比,CW-V 和 CW-B 对 NH4 + -N 和 NO3- -N 的去除率显著提高(P < 0.05)。温室气体排放量的比较显示,虽然 CW-B 对 NO3- -N 的去除率更高,导致其 N2O 排放量最高,但其脱氮比例仍然最小。此外,由于进水中有机物的快速消耗以及部分 CH4 被氧化为 CO2,三组建造的湿地均未检测到 CH4。研究结果表明,三类基质构建湿地的处理效果和温室气体排放差异显著,该研究可为净化河流污染水体的湿地建设和运行提供一定的科学参考。

The current Chinese electricity market and carbon market are built relatively independently, without coupling and synergy, and the incoherence between the two markets is beginning to emerge. Carbon emissions costs in the carbon trading market will affect the marginal cost of renewable energy and thermal power in the electricity market, limiting market participants’ profitability. In order to simulate and evaluate the changes of LCOE of renewable energy and thermal power in the “electricity-carbon” market environment, this paper presents the calculation method of carbon emission cost of thermal power and CCER benefit of renewable energy based on the relevant regulations in China, and calculates the carbon emission cost transmission rate of thermal power based on Cournot model. In addition, we proposed a method for calculating the LCOE based on the international common calculation method for LCOE, combined with China’s taxation policy and the cost and benefit factors of renewable energy and thermal power in the carbon market, and proposed a method for calculating the LCOE applicable to the “electricity-carbon” market environment in China. The findings indicate that as a result of the influence of the carbon market, the levelized cost of energy (LCOE) cost of thermal power will increase, and the profitability of thermal power in the electricity market will be further reduced. On the other hand, the LCOE cost of renewable energy will further decrease, and its profitability will improve due to the additional CCER benefits in the carbon market.
目前的中国电力市场和碳市场是相对独立构建的,没有耦合和协同,两个市场之间的不连贯性开始显现。碳交易市场中的碳排放成本将影响电力市场中可再生能源和火电的边际成本,限制市场参与者的盈利能力。为了模拟和评估“电碳”市场环境下可再生能源和火电的LCOE变化,本文根据中国的相关规定,提出了火电碳排放成本和可再生能源CCER效益的计算方法,并基于库诺模型计算了火电的碳排放成本传导率。此外,我们在国际通用LCOE计算方法的基础上,结合中国的税收政策以及可再生能源和火电在碳市场中的成本效益因素,提出了一种适用于中国“电碳”市场环境的LCOE的计算方法。研究结果表明,由于碳市场的影响,火电的平准化能源成本(LCOE)将增加,火电在电力市场的盈利能力将进一步降低。另一方面,可再生能源的LCOE成本将进一步降低,其盈利能力将因碳市场中CCER的额外收益而提高。
