Design and Analysis of an Interior Permanent Magnet Synchronous Motor for a Traction Drive Using Multiobjective Optimization

With the development of new energy industries, the demand for the driving range and power quality of electric vehicle (EV) drive systems is growing rapidly. The drive motor is faced with the challenge of continuously improving power density and performance. This paper proposes a multiobjective optimization method for an interior permanent magnet synchronous motor for a traction drive (IPMSMTD). Based on the flat wire winding technology, the multiobjective optimization design of the IPMSMTD is carried out to improve the motor power density and high-efficiency range, reduce the torque ripple, and suppress the electromagnetic vibration and noise. The structure and size equation of the IPMSMTD are described. The mathematical model considering iron losses is established, and the optimization objectives are determined. Based on the genetic algorithm, a multiobjective optimization mechanism of the magnetic pole structure is established. The operation performance of the motor is analyzed by the finite element simulation and efficiency map. In order to ensure the comprehensive operation index of the IPMSMTD, the vibration noise and modal analysis are carried out, which verifies the rationality of the designed motor and the optimization method.

Economic level, environmental regulation, and new energy industry development.

Using panel data of 30 provinces and new energy (NE)-listed enterprises in China from 2011 to 2020, this paper uses basic model to research the impact of various environmental policies in China on NE industry development firstly. Then, using economic level as a threshold variable, a threshold model was constructed to research the impact of economic level on the relationship between environmental regulation and NE industry development. The research results show that firstly, various environmental policies in China have significantly promoted the development of the NE industry. This is mainly manifested in two aspects. One is environmental regulations significantly increased the NE industry output value and profit, the other is environmental regulations enhanced the NE industry growth potential. Secondly, the regional economic level has a significant impact on the relationship between environmental regulations and NE industry development. The promotion effect of environmental regulations on NE industry development depends on the regional economic level. When the regional economic level exceeds the threshold, the promoting effect of environmental regulations on NE industry development significantly increases. The reason is that a weak economic foundation will affect investment in the NE industry. Insufficient capital investment will inevitably seriously hinder the development of the NE industry. Thirdly, residents' education status, financial support, and NE industry agglomeration degree have a positive impact on the development of the NE industry, while population size has no significant impact on NE industry development.

Study on Economic Strategy of Green Finance Promoting the Development of New Energy Industry in Shandong Province

With global climate change and energy security issues becoming increasingly prominent, new energy industry(NEI) has become an important field to promote sustainable development. The purpose of this study is to explore the economic strategy of green finance(GF) in promoting the development of NEI in Shandong Province. Through in-depth research on the policy framework and practical operation of GF, we find that Shandong Province has made remarkable achievements in this field. Green financial policy covers many aspects, such as financial incentives, financial product innovation and policy guidance, which provides strong support for the NEI. On the practical level, the Shandong provincial government has established a close cooperative relationship with financial institutions, and strengthened financial institutions' support for new energy projects through joint loans and risk sharing. Shandong province has made a series of remarkable achievements in the economic strategy of GF promoting the development of NEI, which has laid a solid foundation for future sustainable development. However, it is still necessary to further strengthen supervision and innovate financial products in order to better lead the NEI to the road of high-quality development.

Directly prepared Al-doped FeMoO4 materials from spent hydrogenation catalysts via a low-temperature green process

Environmental-friendly recovery of critical metals from solid wastes directly for new energy materials received lots of concerns. In this paper, the FeMoO4(FMO) materials for new energy storage materials are directly prepared from spent hydrogenation catalysts by “low temperature sodium roasting-water leaching” process. The leaching rates after roasting of main metal element Mo, Al and Ni from wastes are: 91.8 %, 1.7 % and 0.1 %, respectively, then the leachate was directly generated Al-doped FMO materials (Mo/Al = 50:1). As for the application of lithium ion battery anode, the specific capacity is 363.5 mAh/g after 200 cycles, 55 % improvement compared with bare FMO. The tunable phase transformation by roasting temperature regulation is the core to achieve the selective water leaching of Mo, and the intrinsic mechanism have been investigated by calculation and experiments. Finally, the economic evaluation of the whole process shows that for every 1 kg of spent catalyst processed and made into FMO, a profit of $20.8 can be obtained, indicating promising economic benefits. This process provides an environmental technology route for the development of new energy industries under carbon neutrality goals.

Analysis of Business Strategies for the Development of New Energy Industry: A Case Study of BYD Auto Company

Nowadays, global environmental problems have become increasingly serious, in order to deal with climate and environmental problems, China has proposed a dual carbon policy, and actively encouraged the development of a new energy industry, optimizing the energy structure and some methods. This paper adopts the case analysis method, takes the new energy enterprise BYD as an example, studies the development status of new energy enterprises, points out the existing problems, and puts forward relevant countermeasures. This studys discoveries can be summed up into two experiences. The premier test, first and foremost, obstructing BYDs undertaking progress lies in the decreasing benefit of mechanical advancement, dissolving its upper hand. To resolve this issue, it is basic that new energy undertakings focus on development as a foundation of their development technique.Besides, the improvement of these organizations ought to put an uplifted spotlight on developing areas of strength for a culture, putting resources into the ceaseless advancement of their labor force, and upgrading the general information level inside their groups. In addition, the absence of strong foundation supporting the development of new energy ventures. To balance this, it is fundamental for legislatures to expand their help for these ventures, guaranteeing they have the important assets and climate to flourish. By addressing these provokes and offering direction to arising new energy firms, this exploration not just adds to hoisting the business general norms yet additionally holds the possibility to have a huge effect on worldwide natural and biological issues.

Valuation Analysis of Lithium Battery Industry: Evidence from Kedali

In order to solve the problems of energy security and environmental pollution, governments are promoting the development of new energy industries to ensure the sustainable development of the human world. Among the new energy idustries, lithium batteries, as an important part of new energy vehicles, have widely used in recent years with the rise in sales of new energy vehicles. In China, with the increasing competition in the industry, various companies have different performances, and their business conditions affect the development of the entire new energy industry. Therefore, it is very necessary to build a reasonable value evaluation system for lithium battery companies to help related enterprises develop healthily and continue to operate, and market investors better understand the industry situation to make bright investment decisions. Based on the FCFF model, this paper analyzes the valuation of Kedali Company (one of the representative company in China's lithium battery industry), compares the intrinsic value of Kedali with the market value, and comes to the conclusion that the current stock price of Kedali is slightly undervalued. Finally, based on the conclusion, the investment risk analysis is presenetd for market investors, offering them some useful investment decisions.

Impact analysis of mergers and acquisitions on the performance of China's new energy industries

The development of new energy industries is crucial to a nation's energy transition to carbon neutrality, while photovoltaic, wind power, lithium battery, and new energy vehicles industries have been active in the capital markets. We choose mergers and acquisitions (M&A) activities in such industries in China to investigate how they affect firms' short-run market performance and long-run innovation. Using data gathered from 2012 to 2020, we evaluate the degree of stock price volatility with the Carhart four-factor model combined with event study analysis. Changes in innovation after M&A activity has occurred are evaluated using the PSM-DID model. Empirical analysis shows that M&A could have a positive, short-run impact on stock prices of new energy industries, while the impact of technology M&A on sub-industries is not consistent. The cumulative average abnormal returns (CAAR) of the wind power and photovoltaic industries turn from negative to positive, and the correlative new energy vehicles and lithium battery industries reach the highest returns in a window period with similar trend lines. Furthermore, technology M&A positively affects the innovation performance of new energy firms, and this effect lasts three to four years. In contrast to prior industry-wide and conclusion-inconsistent M&A studies, we concentrate on new energy industries and prove the definite positive effect of technology M&A for the firms.

Application of nanotechnology in lithium titanate batteries

With the introduction of dual carbon policy and the development of new energy industry, new energy batteries play a pillar role in the whole industry. However, the new energy batteries made in the context of traditional cathode materials often have many defects and cannot meet the demand. This study introduces nanotechnology, lithium titanate batteries and their integrated applications. Among them, nanofabrication technology, as an emerging technology, can be used to dope new particles to modify the conventional lithium titanate to improve its own shortcomings of insufficient conductivity of a single material. The significance of this thesis is to compare each technique and each material, and to propose new experimental solutions based on the existing research results.

Optimal wind power generation system by honey badger algorithm with differential evolution strategies

The purpose of this study is to build an optimal hybrid wind power system consisting of a permanent magnet direct-drive wind power generation unit, a hybrid energy storage system (HESS), a power electronic converter, and loads. Moreover, a reasonable control method is designed for each part, and a honey badger algorithm (HBA) with differential evolution strategies is employed to realize the coordinated control of each unit and improve the system stability. The real anti-interference capability of wind power system can be improved by the proposed HBA with differential evolution strategies (IHBA). Firstly, the wind hybrid system model is constructed, in which the wind power generation unit adopts the variable step climbing method to achieve the maximum power point tracking control; the HESS designs the power distribution method based on the bus voltage; the converter supplying energy to the AC load introduces the virtual synchronous generator (VSG) control strategy. Secondly, due to the existence of energy exchange in each unit of the system, VSG has more parameters and its control performance is influenced by the system itself, this study proposes HBA with differential evolution strategies for system parameter optimization and constructs an IHBA-VSG model with the objective of minimizing the bus voltage fluctuation value. The IHBA improves original honey badger algorithm by three mechanisms which are time control function, Gaussian variation factor and differential evolution strategy. Finally, the parameters obtained from the HBA with differential evolution strategies optimization search are substituted into the wind hybrid system, and the simulation system is built by MATLAB/Simulink. The simulation results show that when the environment of the system changes or the load on the AC side changes abruptly, the proposed control method can reduce the bus voltage fluctuation by 2.9%− 18.22% compared with the honey badger algorithm Optimized VSG (HBA-VSG), and can reduce the bus voltage fluctuation by 5.09%− 17.98% compared with the traditional droop control without considering the system interaction. This study can effectively improve the stability of wind power generation system and promote the development of new energy industry.

A Quantitative Study on the Impact of China’s Dual Credit Policy on the Development of New Energy Industry Based on Taylor Expansion Description and Cross-Entropy Theory

The Dual Credit Policy is an important policy to promote the development of new energy vehicles unique to China. There is a lack of research that intuitively reflects the impact of the Dual Credit Policy on industrial development through an industry-based factual comparison of this policy. Based on the Taylor expansion and Cross-Entropy description, this article obtains the development regression function by the quantitative analysis of five indicators—the number of new energy vehicle-related patents, sales volume, production volume, the number of newly registered enterprises, infrastructure construction (the number of charging piles) before and after the implementation of the policy, and describes them quantitatively using the Taylor expansion to obtain the CPTI index. The CPCEI index is obtained by calculating the Cross-Entropy of the distribution of each indicator before and after policy implementation. The above two indices were compared for the growth trend and growth quantity, respectively. Finally, the following conclusions were obtained: 1. the Dual Credit Policy is more significantly promoted at the market level than the impact on the technical level; 2. although there is also incentive in infrastructure construction, it cannot fully react to the market demand; 3. the number of start-up’s operating in the new energy field increases, but the overall growth trend gradually slows down and fails to significantly change the existing structure of the market. This study suggests that the government should launch a special incentive policy for charging piles, and new energy manufacturers should expand their production capacity to meet the market demand.

The Impact of International Oil Price Fluctuations on Chinas Stock Performance of Clean Energy Industry: Under the Russia-Ukraine Conflict

Crude oil is an important component of the global energy market, and its price fluctuations have a huge impact on the economy and the environment. As a large oil consumer, China has a great demand for non-renewable resources such as crude oil. With the sustainable and stable development of China's economy, its dependence on imported crude oil is deepening, and the impact of international crude oil price fluctuations on China's energy industry is also gradually deepening. In addition, with the impact of epidemic, geopolitical, environmental crisis and financial crisis in recent years, the international crude oil price has produced drastic fluctuations, so the study of the relationship between the international crude oil futures price fluctuations and the stock prices of clean energy companies is of great significance for the development of new energy industry and domestic energy security. This paper applies the VAR model to examine the links between Brent crude oil index, WTI crude oil index and Chinas Clean Energy Theme Index (CET), and the ARMA-GARCHX model to investigate the impact of international oil price on Chinas clean energy market after the Russia-Ukraine conflict. The empirical results show that international crude oil price fluctuation has a short-term alternating impact on Chinas clean energy theme index yield and provides useful insights to investors.

Lithium-Rich Pegmatite Detection Integrating High-Resolution and Hyperspectral Satellite Data in Zhawulong Area, Western Sichuan, China

Lithium (Li) has grown to be a strategic key metal due to the enormous demand for the development of new energy industries over the world. As one of the most significant sources of Li resources, pegmatite-type Li deposits hold a large share of the mining market. In recent years, several large and super-large spodumene (Spd)-rich pegmatite deposits have been discovered successively in the Hoh-Xil–Songpan-Garzê (HXSG) orogenic belt of the northern Tibetan Plateau, indicative of the great Li prospecting potential of this belt. Hyperspectral remote sensing (HRS), as a rapidly developing exploration technology, is especially sensitive to the identification of alteration minerals, and has made important breakthroughs in porphyry copper deposit exploration. However, due to the small width of the pegmatite dykes and the lack of typical alteration zones, the ability of HRS in the exploration of Li-rich pegmatite deposits remains to be explored. In this study, Li-rich pegmatite anomalies were directly extracted from ZY1-02D hyperspectral imagery in the Zhawulong (ZWL) area of western Sichuan, China, using target detection techniques including Adaptive Cosine Estimator (ACE), Constrained Energy Minimization (CEM), Spectral Angle Mapper (SAM), and SAM with BandMax (SAMBM). Further, the Li-rich anomalies were superimposed with the distribution of pegmatite dykes delineated based on GF-2 high-resolution imagery. Our final results accurately identified the known range of Spd pegmatite dykes and further predicted two new exploration target areas. The approaches used in this study could be easily extended to other potential mineralization areas to discover new rare metal pegmatite deposits on the Tibetan Plateau.

Research on the Spillover Effect of Different Types of Technological Innovation on New Energy Industry: Taking China’s Solar Photovoltaic as an Example

Technological innovation has always played a very important role in the development of new energy industries. This paper takes the solar photovoltaic industry as an object of study, taking into account the diffusion of technological advances and the different roles of different technological innovations, and uses a spatial econometric SDM model to analyze the spillover effects of different types of technological advances on the solar industry in China. It is found that for the PV industry, efficiency-enhancing technological advances have the most significant impact, with efficiency-enhancing technologies contributing significantly to the annual electricity production of the PV industry; safety-enhancing technological advances having the second highest impact on the industry’s development; and cost-reducing technological advances have no significant impact on the industry. The study also found that due to the positive externalities of technological innovation, the spillover effect of technological innovation between regions has a significant impact on the development of the regional solar PV industry. In the long term, the direct effect of efficiency-enhancing technological innovation on the development of the PV industry is significantly positive, while the direct effect of safety-enhancing technological innovation on the development of the PV industry is significantly negative. Therefore, in the future, China’s solar energy industry should combine the capital investment of different types of science and technology into research and development, fully consider the impact of regional and technological spillover on industrial development, use technological innovation spillover to promote technological exchange and progress, and continuously improve the level of equipment operation safety, output efficiency, and electricity cost.

How can we make an orderly transition away from fossil fuels? A global tour of modern energy

This paper analyzes the economic, social and political three-dimensional driving effects of new energy substitution for fossil energy under the joint action of market, government and international competition from three perspectives: profit motive, mutual benefit and responsibility motive, combined with the relevant data of 78 countries from 1965 to 2021. The results show that fossil energy prices and energy security positively influence the process of new energy substitution, and environmental pollution negatively affects the process of new energy substitution, and the pushback effect of energy security on new energy substitution is more significant in the study interval, indicating that at the beginning of the new energy revolution, global environmental governance and willingness to reduce emissions drive the development of new energy industry, but the “carbon emission reduction” of each country has increased the complexity of new energy substitution, especially in some developed countries in taking responsibility for global environmental governance divergent views. Further heterogeneity analysis reveals that each country’s energy strategy affects the degree of substitution of “quality” and “quantity” of new energy, and the speed, areas and corrective ability of new energy development vary among countries under different strategic choices.

Recovery of lithium from brine with different degrees of mineralization by resorcinol/urea–formaldehyde foam-supported H2TiO3

With the development of new energy industry, the extraction of lithium from liquid minerals has attracted extensive attention. Herein, a novel phenolic resin-supported H2TiO3 foam (RF/UF-HTO) was developed for Li+ recovery from aqueous solutions. It was found that when the thermosetting phenolic resin was modified with urea and then foamed by petroleum ether with boiling points of 60 ∼ 90 °C under the assistance of 1.5% Tween 80 + 3% sodium dodecyl sulfate, the material presented a porous 3D network structure with a high specific surface area and porosity. The maximum adsorption capacity of the material reached 52.41 mg·g−1. The adsorption rate was controlled by the particle diffusion, and the adsorption was proven to be an endothermic process by the microcalorimetry. The material exhibited high adsorption performance for low-concentration Li+ in geothermal water with a low degree of mineralization. The adsorption capacity reached 21.50 mg·g−1 after only 6 h, and the attenuation of adsorption capacity was only 1.96 mg·g−1 after 10 cycles. Because of the high Mg2+ concentration and high degree of mineralization, the adsorption capacity for Li+ in salt lake brine was low. This problem was successfully solved by regeneration with Ba(OH)2, by which the adsorption capacity was enhanced from 0.54 to 20.72 mg·g−1. Even for the fixed-bed adsorption, the adsorption capacity still reached 8.5 mg·g−1. Based on these excellent properties, the material and method developed in this work can be used for Li+ recovery from brine with different degrees of mineralization and composition.

How the new energy industry contributes to carbon reduction? —Evidence from China

New energy is an inevitable choice to cope with global climate change. China has invested heavily in new energy, but it still faces enormous pressure to reduce emissions. The effectiveness and path of new energy industry development still need to be solved. This paper studies the relationship between the development of new energy industry and carbon emissions. A theoretical model of new energy firms’ production behaviour was constructed, reflecting that the internal carbon emissions of the new energy industry mainly depend on its cost structure and R&D intensity. Specifically, part of the carbon emission caused by scale effect comes from direct capacity construction, and the other part comes from the production-cost effect of R&D. Based on the provincial panel data in China from 2005 to 2019, empirical tests are carried out from two aspects of scale effect and technology effect. Results show that the scale expansion has an inverted U-shaped relationship with carbon emissions, which is supported by the regression with GDP as the threshold variable. The effect of new energy technologies in reducing emissions is continuous. The threshold for technology to play a role in reducing emissions is smaller than the threshold for scale. The findings explain the expansion of the new energy industry in the early stages may lead to an increase in carbon emissions. Our study provides important insights that the scale and technology are two dimensions that cannot be ignored in the process of energy transformation. It is necessary to act in the reasonable range and pay attention to the accumulation of technology innovation and the orderly expansion of production capacity.

Clean energy-based rural low carbon transformation considering the supply and demand of new energy under government participation: A three-participators game model

Since the 20th century, human society has developed rapidly, and with the continuous development of urbanization, serious environmental pollution problems have followed. Actively studying the development of new energy industry has become an important issue around the world. Rural energy is an important foundation of rural economic and development. Promoting green energy transformation and development in rural areas is an inherent requirement to meet people’s needs for a better life and an important part of building a modern energy system. This study constructs a tripartite evolutionary game model of the government, new energy enterprises and farmers, and analyzes the evolutionary path and stable strategy of the three participants in the process of energy industry transformation. The results show that (1) moderate or high level of government subsidies for farmers use of new energy can promote the development of new energy industry, while low level of subsidies is not conducive to the development of rural new energy industry. (2) When the government’s investment in new energy infrastructure construction is low, farmers will choose to use new energy passively. When the government’s investment in new energy infrastructure construction is moderate or high, farmers will choose to actively use new energy, and new energy enterprises will evolve to actively produce new energy under the circumstance of active use by farmers. (3) Under the current development situation of rural new energy industry, the smaller the proportion coefficient of pollution control costs borne by new energy enterprises formulated by the government, the more conducive the evolution of new energy enterprises to actively produce new energy. Perfect farmers use of new energy countermeasures for the benign development of new energy industry is of great significance. Therefore, from the perspective of evolutionary game, we should promote the transformation of environmental governance to public governance mode. A basic framework for a tripartite coordination mechanism among farmers, the government and enterprises will be established. At the same time, the establishment of specific systems and policies will guide the interests of farmers, the government and new energy enterprises, so as to truly realize the positive development of the new energy industry driven by the participation of three parties.

Empirical analysis of the role of new energy transition in promoting china’s economy

In order to accelerate the development of new energy industry and social economy, this paper presents an empirical analysis of the role of new energy transformation in promoting China’s economy. On the basis of analyzing the concept and types of new energy, the necessity of transformation and upgrading of new energy industry is discussed. The new energy consumption data from 2010 to 2020 and China’s GDP data are selected as the basic data, and the MS-VAR model is used as the base model for the empirical analysis. The model combines the Markov zone transition model and the autoregressive model, which is suitable for analyzing non-linear problems. The results of the empirical analysis show that the new energy transition is an important way to promote new energy consumption, and it plays a role in promoting the balanced development of China’s economic growth. Combining the results of the empirical analysis, this paper gives suggestions related to the new energy transition from the institutional, economic and technological perspectives.

Analysis of the Possibility of Slowing Down the Melting of Arctic Glaciers from the Perspective of the Global Energy Economy

In 2020, Antarctica's surface temperature exceeded 20 degrees Fahrenheit for the first time. This also demonstrates that global warming has become a very significant issue that will cause a number of problems for the planet's species and ecosystem. Many people think that global warming is an old-fashioned problem, but in fact, most people are far from correctly recognizing the terrible consequences caused by global warming. Therefore, this paper studies the problem of glacier melting and analyzes the impact of the development of new energy industry on delaying glacier melting. The results show that the goal of global rise of 1.5 C is difficult to achieve and requires multi-party cooperation. In the future, global temperature rise is inevitable, and more advanced technology can achieve the goal. It should consider that increasing research and development of new energy technologies to essentially replace petrochemical energy. In terms of economic activities, how to change the existing business model, improve efficiency and reduce carbon emissions is a matter of consideration.
