However, China's energy system continues to retain a high-carbon feature where coal dominates energy production and consumption, which has led to the rapid growth of greenhouse gas emissions and associated serious environmental pollution. It has therefore become an important task for China to consider how to promote the low-carbon development of energy system. This paper summarized the basic trends and challenges for development of low-carbon energy system in China and studied the primary energy consumption and carbon emissions in different scenarios at 10-year intervals between 2010 and 2050. The analysis showed that controlling coal consumption will have an important influence on the control of total carbon emissions and of carbon emission peaking; promotion of non-fossil fuel energies will offer a growing contribution to a low-carbon transition in the medium and long term; the development of carbon capture, utilization, and storage will play a key role in realizing a deep decarbonization pathway, particularly after 2030; and the establishment of a low-carbon power system is crucial for the achievement of low-carbon energy transition. Finally, the strategic considerations and policy suggestions on the development of low-carbon energy systems in China are explored.展开更多

However, the traditional model of economic development will lead to human demand for energy continuing to grow, followed by a growth in emissions of carbon dioxide. Obviously we must ensure that there is rapid economic development, but also to protect the human living environment, which is a very sharp contradiction. A good solution to this conflict is to take a new model of development --- a low-carbon economy. The so-called low-carbon economy refers to the reduction of greenhouse gas emissions, the application of new technologies, new materials and new practices, etc., through improvements, optimization or innovative production and business activities, to achieve the maximum degree of reduction of greenhouse gas emissions, and the formation of a new economic development model, the goal is to mitigate climate change and promote sustainable human development. On how to develop a low-carbon economy, domestic and foreign scholars have been studied from many angles, one of which is a consensus to reduce greenhouse gas emissions through the development and use of low-carbon technologies.展开更多

The number of EVs is growing very fast over the years. However, the high adoption of EVs will impose a burden on the power system, especially for neighborhood level network. In this paper, we propose a mixed control framework for EV charging scheduling to mitigate its impact on the power network. A metric for modeling customer＇s satisfaction is also proposed to compare the user satisfaction for different algorithms. The impacts of the proposed algorithms on EV charging cost, EV penetration and peak power reduction are evaluated with real data for a neighborhood level network. The simulation results demonstrate the effectiveness of the proposed algorithms.展开更多
