Triboelectric nanogenerators: the beginning of blue dream

《化学科学与工程前沿（英文）》 2023年第17卷第6期页码 635-678 doi: 10.1007/s11705-022-2271-y

摘要： Wave energy is inexhaustible renewable energy. Making full use of the huge ocean wave energy resources is the dream of mankind for hundreds of years. Nowadays, the utilization of water wave energy is mainly absorbed and transformed by electromagnetic generators (EMGs) in the form of mechanical energy. However, waves usually have low frequency and uncertainty, which means low power generation efficiency for EMGs. Fortunately, in this slow current and random direction wave case, the triboelectric nanogenerator (TENG) has a relatively stable output power, which is suitable for collecting blue energy. This article summarizes the main research results of TENG in harvesting blue energy. Firstly, based on Maxwell’s displacement current, the basic principle of the nanogenerator is expounded. Then, four working modes and three applications of TENG are introduced, especially the application of TENG in blue energy. TENG currently used in blue energy harvesting is divided into four categories and discussed in detail. After TENG harvests water wave energy, it is meaningless if it cannot be used. Therefore, the modular storage of TENG energy is discussed. The output power of a single TENG unit is relatively low, which cannot meet the demand for high power. Thus, the networking strategy of large-scale TENG is further introduced. TENG’s energy comes from water waves, and each TENG’s output has great randomness, which is very unfavorable for the energy storage after large-scale TENG integration. On this basis, this paper discusses the power management methods of TENG. In addition, in order to further prove its economic and environmental advantages, the economic benefits of TENG are also evaluated. Finally, the development potential of TENG in the field of blue energy and some problems that need to be solved urgently are briefly summarized.

Multi-objective optimal allocation strategy for the energy internet in Huangpu District, Guangzhou, China

Pei LI, Guotian CAI, Yuntao ZHANG, Shangjun KE, Peng WANG, Liping GAO

《能源前沿（英文）》 2020年第14卷第2期页码 241-253 doi: 10.1007/s11708-020-0660-9

摘要： To improve the overall efficiency of the energy system, the basic structure for the energy internet of coordination and optimization of “generation-grid-load-storage” of Huangpu District, Guangzhou, China is designed, while the arrangement for the output of centralized and distributed energy module and energy storage are proposed. Taking economic benefit maximization, environmental benefit maximization and energy efficiency maximization as sub-objectives, the mathematical model of multi-objective optimal allocation and operation strategy of the energy internet is established considering supply-demand balance constraints, equipment characteristic constraints, operation mode constraints, and energy conditions constraints. The calculation results show that without considering the outsourced electricity, the balanced strategy, the economic development strategy, the environmental protection strategy, and the energy efficiency strategy are obtained by calculation, which are all superior to the traditional energy supply strategy. Moreover, considering the outsourced electricity, the proportion of outsourced electricity to total electricity is 19.8%, which is the system optimization of the energy internet under certain power demand. Compared with other strategies without outsourced electricity, the outsourced electricity strategy can have a certain emission reduction effect, but at the same time reduce the economic benefit. Furthermore, the huge difference in demand for thermal and cooling load between industrial and commercial areas results in the installed capacity of gas distributed energy stations in industrial areas being nearly twice as large as that in commercial areas. The distributed photovoltaic power generation is allocated according to the proportion of the installed roof areas of photovoltaic power generation system in residential, industrial, and commercial areas.

A genetic algorithm based improved optimal sizing strategy for solar-wind-battery hybrid system usingenergy filter algorithm

Aeidapu MAHESH, Kanwarjit Singh SANDHU

《能源前沿（英文）》 2020年第14卷第1期页码 139-151 doi: 10.1007/s11708-017-0484-4

摘要： In this paper, the genetic algorithm (GA) is applied to optimize a grid connected solar photovoltaic (PV)-wind-battery hybrid system using a novel energy filter algorithm. The main objective of this paper is to minimize the total cost of the hybrid system, while maintaining its reliability. Along with the reliability constraint, some of the important parameters, such as full utilization of complementary nature of PV and wind systems, fluctuations of power injected into the grid and the battery’s state of charge (SOC), have also been considered for the effective sizing of the hybrid system. A novel energy filter algorithm for smoothing the power injected into the grid has been proposed. To validate the proposed method, a detailed case study has been conducted. The results of the case study for different cases, with and without employing the energy filter algorithm, have been presented to demonstrate the effectiveness of the proposed sizing strategy.

PWR-FBR with closed fuel cycle for a sustainable nuclear energy supply in China

XU Mi

《能源前沿（英文）》 2007年第1卷第2期页码 129-134 doi: 10.1007/s11708-007-0016-8

摘要： From the thermal reactor to the fast reactor and then to the fusion reactor; this is the three-step strategy that has been decided for a sustainable nuclear energy supply in China. As the main thermal reactor type, the commercialized development phase of the pressurized water reactor (PWR) has been stepped up. The development of the fast reactor (FBR) is still in the early stage, marked by China experimental fast reactor (CEFR), which is currently under construction. According to the strategy study on the fast reactor development in China, its engineering development will be divided into three steps: the CEFR with a power of 65 MWt/20 MWe; the China prototype fast reactor (CPFR) with a power of 1 500 MWt/600 MWe; and the China demonstration fast reactor (CDFR) with a power of 2 500 3 750 MWt/1 000 1 500 MWe. With regards to the fuel cycle, a 100 t/a PWR spent fuel reprocessing pilot plant and a 500 kg/ a MOX fabrication plant are under construction. A project involving the construction of an industrial reprocessing plant and an MOX fabrication plant are also under application phase.
