The rapid depletion of fossil fuels and the growing concerns over environmental sustainability call for the exploitation of renewable carbon resources. The past 2 decades have witnessed rapid development of the production of fuels, chemicals, and other products from biomass and organic solid wastes via both thermochemical and biochemical processes. Thermochemical processes, such as combustion, gasification, pyrolysis, hydrothermal processing, and solvent liquefaction, have been developed as promising routes for the green, lowcost, and sustainable utilization of biomass and organic wastes. In the past 20 years, china has made significant progress in research and development (R&D) related to thermochemical processing of biomass and solid wastes, including fundamental reaction mechanisms and kinetics, lab- and demonstrationscale reactor design and operation, complex modeling, and process simulation. Globally, china is one of the most active countries to present cutting-edge research, interdisciplinary and original study, and emerging growth areas related to technologies for processing biomass and solid wastes. This has been the motivation for the publication of the current virtual special issue (VSI) “Recent Research Advances in china: Thermochemical Processing of Biomass and Solid Wastes”. This VSI aims at reporting a summary of the latest advances and trends of R&D on thermochemical processing of biomass and solid wastes in china. It focuses on mostly thermochemical processing of biomass and solid wastes related topics, including (1) experimental studies on thermochemical processes, including but not limited to combustion, gasification, pyrolysis, hydrothermal processing, and solvent liquefaction, (2) computational modeling of thermochemical processes, (3) techno-economic and life cycle assessment of thermochemical processes, and (4) fundamental research and technological development on hybrid processes, including those intersecting with the use of solar energy.

As an essential direction of agricultural development in the future, the energy demand for facility agriculture varies significantly in different seasons. In this paper, an integrated energy network structure for independent facility agriculture with combined heat and power enhanced geothermal system (CHP-EGS) is proposed. Based on the CHPEGS cogeneration model and stochastic optimization method, the optimal analysis model for capacity allocation of independent facility agricultural integrated energy network is established. Taking the energy supply of facility agriculture in the hot dry rock resource-rich area of the Gonghe basin in china as an example, the optimal allocation scheme and operation characteristics of integrated energy networks for facility agriculture are analyzed considering the difference of seasonal energy consumption. The results show that, under the same capacity configuration, facility agriculture has sufficient energy support in summer, and its income can be increased by expanding the area of greenhouse or developing product processing. In winter, if the basic energy supply-demand of facility agriculture is to be ensured, the emergency heating system should be configured according to about 30% of the maximum heating demand. The optimization model and case analysis can provide meaningful guidance for seasonal energy sources planning of facility agriculture. © 2020 IEEE.

Medium and long-term weather sequence forecast becomes unreliable beyond two weeks since the weather is a chaotic system. Using values of same months for electricity prediction of wind power is the usual method. This approach defaults wind power output with annual cycle law. However, the periodic pattern can be very complicated in fact with multiple time scales. This paper proposes an approach with multi-scale periodic pattern considered. The application of parametric estimation on cumulative distribution function avoids the difficulty of predicting the power curve. Meteorological condition is considered to some extent via multi-scale periodic pattern explored basing on historical energy data. This work is an exploration for medium and long-term wind power forecasting that can well adapt to existing conditions. It has better prediction accuracy than the method without multi-scale periodicity considered. © 2020 The Authors, published by EDP Sciences.

55GW distributed photovoltaic have been installed in china, but nearly half are connected to the low voltage level of 380V, without real-time power data acquisition. The sequential power data is needed to be reconstructed based on some related monitoring data. Current researches focus on outliers recovery, but not reconstruction from none. This paper explores the temporal and spatial correlation of power between adjacent centralized photovoltaic stations and proposes a large-scale missing power data reconstructing method based on the time-delay power correlation, the spatial geometric characteristics of stations and the thought of ensemble learning. Finally, we verify the effectiveness of the proposed method by simulation based on the real photovoltaic power data. The proposed method can get the better effect of data reconstructing compared with the traditional method, which only use the power curves of the nearest CP station to reconstruct the power curves of the DP station according the capacity conversion. © 2020 The Authors, published by EDP Sciences.

This paper studies the aging characteristics of Ca-doped ZnO varistors when the accelerated AC aging chargeability is 0.9 (135°C/ 1000h). Ca-doped ZnO varistors not only there are good breakdown voltage and low leakage current, according to the current-voltage and capacitance-voltage characteristic curves of ZnO varistor before and after aging. After the aging, the breakdown voltage and leakage current change rate are small. The ZnO varistor doped with Ca can slow down the aging speed to a certain extent and has good stability under the AC electric field. © 2022, The Authors. All rights reserved.

Journal of Thermal Science 2020年第2期29卷 408-422页

Changchun 130011China

The exergy analysis of an electric vehicle heat pump air conditioning system(HPACS) with battery thermal management system was carried out by studying the exergy loss of each component. The results indicate that the compressor is the main source of system exergy loss in all operation conditions. The exergy loss distribution of HPACS is almost the same when the battery thermal management system integrated into the HPACS in cabin and battery mixed cooling mode and the system exergy loss was linearly related to the compressor speed in cooling modes. The performance of the HPACS is better than that of the positive temperature coefficient(PTC) heater in cabin heating mode. The degree of exergy efficiency improvement of the alternative mode was discussed at all operation conditions in cabin heating mode. The results indicate that the optimization effect using the electric vehicle HPACS to replace the PTC heater is obvious at lower compressor speed, surrounding temperature and internal condenser air flow rate.
