Abstract
Dealing with Renewable Energy Resources (RERs) requires sophisticated design and operation along with state of the art technologies. Among many possible ways for handling RERs, to examine a possibility on Demand Response (DR) of power system, a questionnaire survey of an acceptable condition to electricity power out was conducted. As a result, answers of not accept outage were increased in case of more times and longer duration of power out. In addition, the percentage of accepting outage was clearly higher in women compared to men and higher in persons taking the energy-saving action compared to persons not taking the action. Such findings were considered to be useful for analyzing relationships between quality of electricity and price, and/or studying demand side management under decentralized renewable energy supply system.
