During the utilization of PHEV, frequently discharge and charge cycles will inevitably lead to the battery aging, which affects the energy management and further affects the vehicular economy. The main purpose of this paper is to investigate the influence of battery aging on energy management economy for PHEV. Four lithium cells under different SoH are used to represent four different aging conditions...
The work is devoted to solving the urgent problem of developing scientific grounds of modernization and innovation industrial development of the North and the Arctic of the Russian Federation under the conditions of resource restrictions, first of all investment and financial ones. The goal of the research is to elaborate theoretical and methodological grounds for potentialities of modernization and...
Typical working conditions and application scenes of backup batteries for communication base station in China are analyzed in this article. And the mathematical model is established for economic analysis of the application of second-use of electric vehicle batteries in backup power for Chinese communication base station. The cost savings ratio in different remaining cycle life of second-use electric...
The exhaust gas from the ocean going ship produced by the auxiliary diesel generator brings serious pollution to the environment of the ports and cities. Based on the reality and the development trends, the paper studies the safety and economy of utilizing shore power supply system for ocean going ship. Firstly, the stability and reliability of the existing shore power technology are summarized and...
In 2016, South Africa's, steel production was down by 4.5% year-on-year. This was due to both a struggling economy and a world surplus in steel supply. Therefore, in order for South Africa to remain competitive in the global steel market, the current emphasis on cost reduction needs to be maintained. It is thus important for personnel at iron- and steel-manufacturing plants to be aware of the risks...
While the regular optimal power flow model focuses on a single time scan, the optimization of power systems is typically intended for a time duration with respect to a desired objective function. In this paper, a temporal optimal power flow model for a time period is proposed. To reduce the computation burden needed for calculating temporal optimal power flow, a characteristic optimal power flow model...
The main objective of this study is to estimate the relationship between foreign direct investment (FDI), trade openess, and economic growth in Lao PDR. This article uses time series data from 1990 to 2015. To utilizeswith the most advance technique of bounds testing (ARDL) Cointegration Approach. More over, the Vector Error Correction (VECM) has been investigated to study the long run and short run...
With growing attention to energy conservation and emission reduction, solar energy is used in various fields as the basic renewable energy source and the maximum amount of energy that can be exploited in the world today is used in various fields. Therefore, a composite type combined heating operation mode based on solar collector, ground source heat pump and heat storage electric boiler in the integration...
Ghana in the mid-1990s launched a long-term development plan to transforms its low-income country status into an upper middle-income economy by 2020. The plan envisaged accelerating the average annual real GDP growth of about 4.4% in the 1990s to around 8.3% per annum by 2020. The sustainability of the energy required by the economic transformation was investigated by Energy Commission which in 2006...
While forestry is an important economic factor, the common methods used to estimate potential financial gains from undertaking a harvest project in Germany are usually based on heuristics and experience. Experience-based estimation methods focus on utilizing a few general statistical parameters that define the harvest operation, employing an abstract view on wood harvesting. To improve the accuracy...
High uncertainties in day-ahead unit commitment (UC) introduced by the deviation of wind power forecast error require high amount of spinning reserve, which counteracts the cost and fossil energy saving contributed by wind power integration. To mitigate the above problem, a two-level unit commitment coordinated strategy (TLUCCS) is presented based on the characteristic of wind power forecast accuracy...
Alternative economic approaches are gaining importance due to the extreme inequalities caused by the laissez-faire perspective of neoliberal economics. These approaches study the economy with a multidisciplinary view, considering paradigms of social inclusion, justice and sustainability. Geographic information science (GIScience) can be defined as a multidisciplinary and a multiparadigmatic field,...
This research refers to taking the 280kW engine which matches the “6 × 4” semi-trailer towed vehicle as the principal part and conducts the acceleration test and economy test respectively according to the direct gear and overdrive gear of the transmission by assembling the bridge with different ratios. Furthermore, the vehicle matching optimal design is determined by analyzing the obtained dynamic...
This book aims to develop a new conception of creative industries, a term largely associated with the aggregated economic activity of artists. Hartley, Wen, and Li expand the scope of creative industries by defining creativity as newness of any variety and arguing that newness emerges from groups communicating with each other. This wide definition of creative industries invites scholars of entrepreneurship...
Fish poisoning can be life threatening and it is important to detect the causes of fish poisoning, and the type of fish poisoning, reliably and accurately. However, the existing research on fish poisoning has generally focused on statistical methods and specific areas within the fish poisoning field. This review based research also highlights the possibilities of data mining in this area, especially...
In order to reduce the cost of the expensive hybrid HVDC breaker, a H-bridge type HVDC breaker is proposed in this paper, and different fault isolation strategies are studied in the combination of positive and negative poles. The key components and fault isolation principle of the hybrid HVDC breaker are used in the H-bridge type HVDC breaker. According to the characteristic of current flow direction...
With the increasing access number of microgrids in a single district, multiple microgrid gradually form more complex operation mode and control method in the system called Multi-microgrids. Aiming at the PV-ESS Multi-microgrid of higher commercial value, and based on single-three phase Hybrid Multi-microgrids, we propose a day-ahead economic optimization strategy considering fuzzy rectification and...
This paper highlights the Economics of Wind Energy in Pakistan. Pakistan is developing country and is facing energy crisis since past. Pakistan has been blessed with natural resources but they did not utilize these resources. Currently power generation is not enough to meet the power needs and as a result there is huge gap between demand and supply in energy sectors. The demand of energy exceeds the...
A key requirement in preparing for a growing UAS industry and for the integration of unmanned vehicles into the US national airspace, is a method for clear and specific forecasting. We must know what types of operations are being performed, where they will occur, and what types of vehicles will be used. Current demand forecast models are not tightly coupled to the real purpose of the mission requirements...
Combined cooling, heating and power (CCHP) system has been widely used all over the world due to its high efficiency, environmental protection, economy and reliability. The basic meaning and significance of CCHP are presented. The CCHP system for active distribution network is proposed in view of the deficiency in the current CCHP system. In this work, the process and advantage of this system are...
