Mixtures of wood chips and either bentonite or kaolin were co-pyrolysed at temperatures of 350 ☌ and 550 ☌, and the microstructural characteristics and the carbon sequestration potential of the resultant biochar were explored in the study. We argue that reaching the carbon neutrality goal by the end of this century is essential for mitigating the impacts of climate-induced disasters on society, as such goal would help people coping with challenges posed by climatic extremes and drought conditions in a sustainable way.īiochars have been highlighted as a means of carbon sequestration, which is significant for achieving carbon neutrality. By 2100, YRB areas will witness a drier tendency, mainly in upstream and northern region (e.g., Inner Mongolia). Drought conditions under carbon neutrality will be mostly alleviated among all the four warming scenarios. There will be a slight drying trend in YRB for all the three SSPs under four warming scenarios (e.g., 1.5 ☌ and 2.0 ☌ global warming, carbon peak and carbon neutrality) compare with the reference period. When comparing with the reference period (1995–2014), drought conditions after 2040s will markedly be alleviated under the listed three SSPs. From 2015 to 2100, an increasing trend in temperature and precipitation is anticipated in YRB. For this, the monthly climate variables from CMIP6 models are in better agreement with the observation from 1961 to 2014, after (Equidistant Cumulative Distribution Functions) EDCDF Bias Correction method (e.g., the RMSE is reduced by 50% and 25% - 67% for temperature and precipitation, respectively). Based on climate outputs from the Coupled Model Intercomparison Project Phase 6 (CMIP6), we projected future climate conditions and drought characteristics in YRB, especially under the three SSPs (the Shared Socioeconomic Pathways) (e.g., SSP1–2.6, SSP2–4.5, and SSP5–8.5). Yellow River Basin (YRB) in China has been frequently featured as one of the most vulnerable areas to climate change and climatic extremes, mainly due to its fragile arid and semiarid ecosystems.While previous researches mainly focused on the evaluation of historical drought periods, it is also meaningful to understand future drought conditions in YRB, in particular, alleviated drought trends under carbon peak and carbon neutrality periods. The proposed node-related inertia pricing approach can be used to guide properly planning the inertia resources. Case studies on the modified IEEE-39 system and Northwest power grid of China demonstrate the proposed inertia scheduling model can enhance the ability of the system to maintain frequency stability, in the same time with good economy. Accompanied by generation scheduling scheme, the nodal inertia price is also given based on the concept of marginal price according to the duality theory. First, we infer the node-related rate of change of frequency (RoCoF) considering the network constraint according to disturbance power then establish inertia demand constraints of RoCoF for each node and the frequency nadir for the whole system, which are then introduced into establishing the optimal inertia scheduling model. In this paper, we propose an approach on pricing the nodal inertia.

In addition, with increasing importance of inertia and the difference in inertia provision at different nodes by a variety of regulation resources, it is important to analyze nodal inertia economic value and compensate units accordingly.

Therefore, it poses a novel problem how to reasonably schedule the inertia on the premise of the spatial distribution characteristics of dynamic frequency in the power system operation. Large-scale integration of variable renewable resources (such as wind power) not only leads to the reduction of inertia, but also changes the spatial distribution of inertia in the power system, which raises spatial-related dynamic frequency instability risk.
