Decomposition of air conditioning electricity consumption considering the dependence between the temperature and electricity consumption.

With the continuous increase in air conditioning installations, the proportion of air conditioning electricity consumption to total electricity consumption is growing. Research on the decomposition of air conditioning electricity consumption is of great significance for assessing electricity usage, formulating electricity scheduling plans, and ensuring the stable operation of the power grid. Currently, typical day selection strategies for the decomposition of air conditioning electricity consumption often overlook the corresponding relationship between typical daily electricity consumption and temperature.

Decomposition of air conditioning electricity consumption based on effective duration.

As the share of air conditioning electricity consumption within total grid electricity consumption grows, the decomposition of such consumption becomes increasingly crucial for assessing electricity usage patterns, devising consumption scheduling strategies, and maintaining the stability of the power grid. Although there is a strong correlation between apparent temperature and air conditioning electricity consumption, the literature currently available seldom explores the impact of apparent temperature on this consumption. Moreover, there is a scarcity of effective assessment indices to evaluate the efficacy of air conditioning electricity consumption breakdown.

Chemical and Genetic Diversity of Ligularia hodgsonii in China.

Ligularia hodgsonii was found to be diverse in China. Furanoeremophilanes were isolated from samples collected in Yunnan Province, while such compounds were absent from samples from Sichuan, Gansu, and Chongqing. DNA sequencing showed that the Yunnan samples were also genetically distinct.

Chemical and genetic differentiation of Ligularia hodgsonii in Japan and China.

The chemical composition of the root extract and neutral base sequences of L. hodgsonii samples collected in Japan and China were examined. From the Japanese and the Chinese samples, 6beta-(angeloyloxy)furanoeremophilan-15-oic acid and 3beta-acetoxy-6beta-[(2-methylbutanoyl)oxy]furanoeremophilan-10beta-ol were isolated as the major component, respectively.
