As a major part of household electricity load in summer, air conditioning (AC) consumption demonstrates enormous demand response (DR) potentials and numerous AC based DR programs are carried out annually. Understanding electricity consumption behaviors is one of the key elements for utilities to design more cost-effective DR programs. So studying on the AC electricity usage habits is of great significance...
The objective of this study was to estimate rice growth parameters (LAI, crop height) in a timely and precise manner with FQ Radarsat-2 images. The proposed approach is based on the water cloud model, five Radarsat-2 images and coincident ground measurements obtained in Chizhou, in the Anhui province of Central China, during a single-cropping rice growth stage in 2014. This study investigated the...
Network-of-Networks (NoN) is the latest developments of Complex Network, which is suitable for researching problem of System-of-Systems(SoS). We put forward a conceptual model of military SoS based on NoN, the model can describe various dynamic and static factors of SoS effectively. The SoS is mapped into physical network, relationship network and interaction network. The interaction network is defined...
The periodic sampling strategy simplifies the analysis and implementation of generator excitation control in power system. However, it may lead to unreasonable distribution of the resources because the sampling frequency has to indicate the worst scenario of the system operation. The paper applies the self-triggered control algorithm to design the generator excitation controller of power system. The...
With the increase of the applications of EHV transmission lines operation, electromagnetic pollutions caused by power lines attract more people's attention. So researching on the electric field intensity at operating frequency of EHV transmission lines is very meaningful for the EHV transmission lines' design and the measurement of the surrounding electromagnetic environment. Firstly, this paper sets...
In view of the difficulty of modeling for complex nonlinear system, a novel one step iterative identification algorithm for the linear part of the system is proposed in this paper, based on Taylor series expansion. The effect of sample on the precision of the model was analyzed by utilizing rigorous mathematical theory, and neuro-fuzzy model was used to identify the Taylor remainder and noise. To...
Now there are many prediction models based on grey theory, however, the precision, adaptability and efficiency may be quietly different, so it is essential to choose a more suitable prediction model for the stability evaluation of tunnel surrounding rock-support system. In the paper, some typical grey prediction models were discussed and compared from aspects of precision, adaptability, computational...
This article used VAR model to analyze and verify the symbiosis between Chinese coal mining machinery enterprises and coal mining enterprises from the perspective of static state and dynamic state, it concluded that: there is a co-integration relationship between the actual output value of Chinese coal mining machinery enterprises and the actual value of Chinese coal mining enterprises, namely, there...
Based on the data collected from 1990 to 2005, this paper explores the short-term and long-term relationship between Henan's Export Pattern and economic growth by applying co-integration analysis, Granger causality test, as well as ECM. The conclusion is: There is a long-term equilibrium relationship between Henan's economic growth, primary products export and manufactured goods export; each of those...
