| 1 | Heat and power load dispatching considering energy storage of district heating system and electric boilers显示文摘As one of promising clean and low-emission energy, wind power is being rapidly developed in China.However, it faces serious problem of wind curtailment,particularly in northeast China, where combined heat and power(CHP) units cover a large proportion of the district heat supply. Due to the inherent strong coupling between the power and the heat load, the operational flexibility of CHP units is severely restricted in winter to meet the heat supply demand, which imparts considerable stress on the wind power connection to the grid. To promote the integration of wind power and enhance the flexibility of CHP units, this paper presented a method of heat and power load dispatching by exploring the energy storage ability of electric heating boilers and district heating systems. The optimization results indicate that the proposed method can integrate additional wind power into the grid and reduce the coal consumption of CHP units over the optimized period. Furthermore, the thermal inertia of a district heating system is found to contribute more to the reduction of coal consumption, whereas the electric heating boilers contribute to lower wind curtailment. | Xianzheng HUANG Zhaofeng XU Yong SUN Yali XUE Zhe WANG Zhijun LIU Zhenyuan LI Weidou NI | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，5： | 20 |
| 2 | An overview of the development history and technical progress of China's coal-fired power industry显示文摘As the main power source of China, coalfired power industry has achieved a great progress in installed capacity, manufacturing technologies, thermal efficiency, as well as pollutant control during the past century. With the fast development of renewable energies, coal-fired power industry is experiencing a strategic transformation. To specify the development of coal-fired power industry, its development history is reviewed and the technical progresses on aspects of thermal efficiency, pollutants control and peaking shaving capacity are discussed. It is concluded that the role of China's coal-fired power source would be transformed from the dominant position to a base position in power source structure. Considering the sustainable development of coal-fired power industry in energy conservation, emission control, and utilization of renewable energies, it is suggested that the national average thermal efficiency should be improved by continual up-gradation of units by using advanced technologies and eliminating outdated capacity. Moreover, the emission standard of air pollutants should not be stricter any more in coal-fired power industry. Furthermore, the huge amount of combined heat and power (CHP) coal-fired units should be operated in a decoupled way, so as to release more than 350 GW regulation capacity for the grid to accept more renewable energy power. | Weiliang WANG Zheng LI Junfu LYU Hai ZHANG Guangxi YUE Weidou NI | 2019 | Frontiers in Energy2019，13，3： | 6 |

| 8 | Energy conservation in China's coal-fired power industry by installing advanced units and organized phasing out backward production显示文摘Coal-fired power is the main power source and the biggest contributor to energy conservation in the past several decades in China.It is generally believed that advanced technology should be counted on for energy conservation.However,a review of the decline in the national average net coal consumption rate(NCCR)of China's coal-fired power industry along with its development over the past few decades indicates that the upgradation of the national unit capacity structure(including installing advanced production and phasing out backward production)plays a more important role.A quantitative study on the effect of the unit capacity structure upgradation on the decline in the national average NCCR suggests that phasing out backward production is the leading factor for the decline in the NCCR in the past decade,followed by the new installation,whose sum contributes to approximately 80%of the decline in the national average NCCR.The new installation has an effective affecting period of about 8 years,during which it would gradually decline from a relatively high value.Since the effect of phasing out backward production may remain at a certain degree given a continual action of phasing out backward capacity,it is suggested that the organized action of phasing out backward production should be insisted on. | Weiliang WANG Junfu LYU Zheng LI Hai ZHANG Guangxi YUE Weidou NI | 2019 | Frontiers in Energy2019，13，4： | 1 |
| 9 | Eliminating Outdated Capacity to Promote Energy Conservation in China’s Coal-Fired Power Industry显示文摘1. Introduction As China’s main power source, the coal-fired power industry has supplied about 80% of electricity in China over the past several decadesy, while consuming roughly half of the coal generated in China [1]. Given China’s resources endowment [2], it will be difficult to change the dominant status of coal in China’s primary energy structure in the near future [3]. | Weiliang Wang Zheng Li Junfu Lyu Weidou Ni | 2019 | Engineering2019，5，2： | 1 |
