Research on a Demand Response Interactive Scheduling Model of Home Load Groups
Qingshan Xu,Xiaoquan Jiao 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.3
In order to solve the problem that the potential between electrical appliances and each power supply is not timely in the current scheduling model, which may leads to high energy consumption and poor interaction performance, the research of interactive scheduling model for demand response of home load group is proposed. Four types of household appliances are obtained from the home load group structure diagram: core electrical appliances, electrical appliances capable of providing storing energy, electrical appliances of any use time, and load aggregators. By selecting multiple indicators, a load group response potential index system is constructed to measure the household based on the impacts of electrical and power response potentials; and two load-aggregate demand response models are established by integrating demand response resources through load aggregation. Furthermore, By combining the above two models with home load aggregation, the improved tabu search algorithm is used to determine the objective function and constraints, such that an interactive scheduling model for the family load group demand response is constructed. The experimental results show that the energy consumption of this model can be low after dispatching household load group. It can reduce household electricity consumption, and have good application performance. The model can efectively complete the interactive scheduling of the demand response of the home load group. It solves the problem of electricity wasting so as to save energy. In the meantime, it improves the user’s real-time and convenient experience.

Nonlinear optical properties of silver colloidal solution by in situ synthesis technique
Yan Deng,Youyi Sun,Pei Wang,Douguo Zhang,Xiaojin Jiao,Hai Ming,Qijing Zhang,Yang Jiao,Xiaoquan Sun 한국물리학회 2008 Current Applied Physics Vol.8 No.1
The silver colloidal solutions were prepared by in situ synthesis technique in the presence of the Polymethyl Methacrylate, which was polymerized by reversible addition-fragmentation transfer. The UV–VIS spectra and transmission electron microscopy had shown the formation of sphere silver nanoparticles with average size of 10 nm. Nonlinear optical properties as a function of silver concentration were studied using Z-scan technique with 13 ns pulse duration at 532 nm. The optical nonlinearity enhancement was observed by increasing the concentration. The third-order nonlinear susceptibility v(3) was measured to 1.045 · 1011 esu when the concentration was 2.13 mg/ml. Besides, the sample was founded to exhibit a shift from saturable absorption to reverse saturable absorption at higher incident laser energy. The reverse saturable absorption was observed to be responsible for the optical limiting characteristics in our experiments. 2007 Published by Elsevier B.V.
