Design And Implementation Of An Intelligent
 Energy Saving System Based On Standby Power 
Reduction For a Future Zero-Energy  Home 
Environment 

  Energy saving has attracted great attention as a global issue 
because of recent environmental problems. As a part of energy 
saving efforts, governments are operating policies that 
encourage the distribution of energy saving systems. Also, 
individual households are voluntarily installing energy saving 
systems to reduce electric power consumption. However, due to 
fixed system architecture, the existing systems have a 
disadvantage, lacking in scalability and usability. In addition, 
the existing systems bring up immense inconvenience as it 
returns to standby mode after automatic standby power cut-off. 
Therefore, we propose an intelligent energy saving system to 
solve these problems. The proposed system controls the power 
based on the hierarchical relationship among home appliances, 
along with the relationship between user activity and home      appliances for standby power reduction. We designed and  implemented the proposed system, deployed it in the test bed, and  measured the total power consumption to verify the system  performance. The proposed system reduces total power  consumption up to 10.5% 1.

Electrical Vehicle Battery Swapping Stations in Distribution System 

Abstract


                   Electric vehicle (EV) is a promising technology for reducing environmental impacts of road transport. In this paper, a framework for optimal design of battery charging/swap stations in distribution systems is presented. The battery charging/swap station models are developed to compare the impacts of rapid-charging stations and battery swap stations. Meanwhile, in order to meet the requirements of increased power provided during the charging period, the distribution network should be reinforced. In order to control this reinforcement cost, stations should be placed at appropriate places and be scaled correctly. The proposed method has been verified on the modified IEEE 15-bus and 43-bus radial distribution systems. The results show that battery swap station is more suitable for public transportation in distribution systems.
