In order to build an environment-friendly society and realize the coordinated allocation and effective utilization of resources and finally achieve China's energy supply security, it is imperative to vigorously develop new energy sources. This study establishes a four-level new energy power generation (NEPG) development index system from multiple dimensions. Taking the installed capacity and generating capacity of China's NEPG in 2016 and 2017 as samples, we used the improved entropy method, to analyze the development of different types of NEPG among 31 provinces from three aspects: absolute value, relative value, and incremental value. Finally, we comprehensively evaluated the NEPG development in each province. The empirical analysis shows that the spatial distribution of NEPG development in China is uneven, the growth rate is different, the development gap is obvious, and the development efficiency is quite different.Energies 2019, 12, 4580 2 of 15 China, it is necessary to improve the regional development of new energy, prioritize the development of new energy sources, and promote the sustainable development of resources and the environment as the overall tone of current resource and economic development [8]. Literature ReviewSince the United Nations Conference on New Energy and Renewable Energy was held in 1981, countries around the world have paid more and more attention to new energy [9]. In September 2015, new energy was listed as one of the UN's sustainable development goals [10]. Domestic and foreign researches on the development of NEPG mainly focuses on three aspects: The first is the influencing factors and policy researches on the development of NEPG; as human beings ignore environmental protection while developing the economy [11], improving relevant policies can promote the development of NEPG [12], which can effectively reduce carbon dioxide emissions [13]. The second is the innovation and development of NEPG technology. Technological innovation plays an effective role in the development of NEPG [14], especially in underdeveloped countries and regions [15]. The third is the trend and significance of the development of NEPG. Traditional energy sources are facing problems such as resource depletion and environmental pollution, and new energy sources can be the best alternative [16]. Since 2000, China's power demand has soared, but power generation efficiency is low [17]. The development of NEPG has become the main focus of China's energy policy [18].The assessment of the development of traditional energy power generation and its impact on the environment economy has been the focus of experts at home and abroad. For example, the spatial correlation model of the economy-energy-pollution phase analyzes the effect of river water as a link between production area and urban living space [19]. The socioeconomic status and energy environment of countries are studied through the energy and environment coupling coordination model [20]. In the energy-economy model, advanced technology has played a decisive rol...

“…Due to the fact that the ratio of renewable energy power generation is gradually increasing, the randomness and uncertainty of renewable energy power generation bring a big challenge for power energy supply. To ensure the energy supply sustainable development safety, it is required that the whole power system must reserve a sufficient safe operation margin, including backup power capacity, energy storage capacity, and power transmission capacity [16]. According to the prediction of the Energy Research Institute of National Development and Reform Commission, the installed capacity of thermal power in China will drop to less than 50% by 2050.…”

Flexibility Transformation Decision-Making Evaluation of Coal-Fired Thermal Power Units Deep Peak Shaving in China

et al. 2021

According to China’s economic green ecological sustainability development requirement, the energy reform of China is mainly increasing the proportion of renewable energy, and reducing the proportion of fossil energy. It will continue to force China’s thermal power units, especially coal-fired thermal power units, to carry out the flexibility transformation and upgrading of deep peak shaving ability. Due to the different characteristics of coal-fired thermal power units, it is necessary to make flexible transformation decisions by a scientific and reasonable decision-making evaluation method, so as to provide references for the one machine-one policy flexibility transformation of thermal power units. In this paper, a decision-making evaluation index system for the flexibility transformation of coal-fired thermal power units under the demand of deep peak shaving is established. The index system considers the impact of deep peak shaving on the boilers, steam turbines, and auxiliary equipment of coal-fired thermal power units, as well as the effects of the peak shaving. A hybrid evaluation method combined set-valued iteration and GRA-TOPSIS is employed to obtain the weight of the indexes. Finally, an empirical research was conducted based on the index system and the hybrid evaluation method and targeted “one machine, one policy” recommendations were put forward for the flexibility transformation of the coal-fired thermal power units.
