To fulfill the Chinese government?s targets for energy conservation and emission reductions, significant efforts to increase efficiency and reduce emissions in the energy system have been made by developing combined heat and power plants, expanding transmission, and incorporating renewables. These elements are not always compatible with each other, however. Renewables in particular face difficulties...
There are 4–6Mt carbon emission resulting from 2,000,000,000 m3 marine sediment. The dredging sediment was removed annually from the waterways around the world. Few efforts have been applied to the evaluation of carbon emission from comparable types of dredger. The carbon emission of four kinds of dredgers which dredged marine sediment was estimated in this paper. Two kinds of representative dredgers...
Due to high risk of unstable supply from fossil energy and growing concern with the preservation of the environment, well-developed Jiangsu province in China is hungering for alternative energy resources to catalyze stupendous economic growth. Assessing the technically available potential of solar energy spatially and temporally over the whole province might be able to improve the unfavorable situation...
This paper investigates the influence on energy consumption by economic structure in China using panel cointegration and Granger causal test with panel vector error correction (VEC) model. The panel cointegration test reveals the long equilibrium relationship between energy consumption and economic structure in China. The Granger causal test with panel VEC model reveals the unidirectional causality...
“China Renewable Energy Law Amendment” has established “renewable energy renewable energy full and security acquisition mechanism”. This mechanism has replaced “renewable energy renewable energy full acquisition mechanism” which can not be effective implemented. This article will analyze the reasons of the new mechanism established from the angle of stakeholders such as government, power grid enterprise,...
By the specific analysis of electricity consumption and water supply in nationwide universities, this paper clearly indicates the level of energy consumption recently in relevant area. Then, according to the different climatic zones, the universities are divided into four groups, such as severe cold, cold, hot summer and cold winter, hot summer and warm winter areas, so that we can analyze and focus...
With seriously lacking resources, coal-fired power still dominates China's power generation today. Not only the low coal utilization but also the low power utilization creates a lot of wastage. During the process of heat release of coal combustion, it produces various atmospheric pollutants, and there is not appropriate treatment for them. Consequently, the environment is facing a serious threat....
Based on a large volume of relevant documents on smart grid, the paper summarized current developing situation of smart grid, including the definition and character description in Europe, America and China. It pointed out that because of different development environment and drive force, different countries' power grid enterprises and organizations comprehend the smart grid concept variously. The...
Aim at cost allocation problem of cogeneration plant products, the paper presents a new heat-electricity product cost allocation method named equivalent allocation method. In the method, the heat-electricity product cost is divided into Fixed Cost and Variable Cost. They are allocated respectively based on the unit type and the equivalent characteristic between heat product and electricity product...
Abstract-Approval standard of electricity price is currently the focus of discussion in the national wind power industry. How to determine an appropriate electricity tariff to promote the sustainable and healthy development of wind power is the urgent problem that wind power company need to solve. In this paper, a generation cost assessment model for wind power is established, taking the cost accounting...
The negative effects of generating power through burning coal on China's ecology are expounded. On the basis of the discussion of the development and application of new type power sources, the paper analyzes the urgency and flexibility of optimizing the structure of the sources of electric power supply and puts forward some countermeasures to the problems.
As a new power distribution logistics means the power industry, power industry has been operating as an important part of the activities. This paper analyzes China's current electricity distribution patterns and defects, then the supply chain model of China's electricity distribution further analysis, given the optimal power distribution planning model.
The energy supply strategy is crucial to promote the application of Battery Electric Vehicles (BEVs). This paper analyzes five decisive elements of the energy supply strategy, which include the characteristics of Chinese urban electric network, the technique of battery and charging, the usage pattern of battery electric vehicles, the effect of energy saving and emission reduction, and the constraint...
In China the intermittence of wind power has become the main difficulties to achievement more wind integration. However most wind measuring data is limited in short period or local areas, which makes it difficult to assess the power fluctuation in a large region. This paper uses the wind speed data obtained from the NASA Goddard Earth Observation System to analyze the fluctuation of wind power in...
On the basis of analyzing the practical significance of developing the straight power purchasing for large power users in China and the advantages and shortcomings of this trade pattern, from the viewpoint of economics and marketing, and combining the electricity market theories and bidding algorithm and so on with straight power purchasing for large power users, the mathematical models are built...
The steady-state stability of UHV demonstration project is low due to large interconnection impedance. In this paper, a DC emergency power control strategy is proposed to improve UHV demonstration project transmission capability by using DC fast adjustment to restrain the tie -line power variation and decrease UHV power oscillation peak value. The simulation results show that the North and Central...
Power sector, as the biggest contributor to the total CO2 emission of China, is faced with tremendous pressure and challenge. The transformation of the whole sector based on the technological innovation and/or introduction appears to be indispensable, which is already recognized by domestic government. Many a measure are taken into practice, such as updating the renewable energies development targets,...
With the concern of possible climate change caused by greenhouse gas emissions from fossil fuel, the world as a community has taken several monumental steps to encourage the development and implementation of renewable technologies and products, mainly wind power, in order to reduce the emission of greenhouse gas. Among countries, the US and China, both with significant wind power capacity, have adopted...
In order to analyze and determine the parameters which influence the pricing strategy of the power company in China, evolutionary game theory and Hawk and Dove game model are used. Given the two types of enterprises in Chinese power market, the large-scale enterprises and the small-scale enterprises, based on the replicator dynamic equations of the pricing strategies of the two types of enterprises...
Building energy consumption refers to various energy used in buildings, including energy consumption in heating, air-conditioning, illumination and hot water supply etc. Based on a comprehensive analysis of all kinds of main factors influencing building energy consumption, this paper simulates the future development tendency of building energy consumption in China through a quantitative analysis so...
