| Popis: | 100 For energy saving, considerable progress has been achieved to improve the efficiency of home appliances. Many literatures regarding peak load reducing and load shifting from peaking to off-peaking period have been explored, and numerous actual examples have been shown. However, only a few researches regarding the electricity expenditure optimization have been proposed. This study aims at an integrated research on optimization of smart home energy saving management information system. In order to achieve this objective, a multi-objective programming (MOP) with genetic algorithm and an analytic hierarchy process (AHP) approaches are utilized. There are three objectives being considered, i.e., total electricity expenditure, total appliances shift time and total appliances shift frequency, which stands for the multi-objectives of “economy”, “convenience” and “comfort” respectively. Then, we utilized AHP to obtain the weight of each goal from 107 market-survey samples of the household sector in Taiwan, with 92 valid responses. After the weights are obtained, we employees MOP with genetic algorithm to search for the final results. This study applies relevant data from related literature and a typical real-time pricing electric rate of a USA power company to undertake the empirical analysis. The results show that this MOP with genetic algorithm enables decision maker to do better energy management on electricity expense under an acceptable level of “convenience” and “comfort”, i.e., while one saves about 9% of the total household electricity monthly bill. The research results derived from this study could reach the goal of optimal electricity bill management in the household sector without significant change of comfortable and convenient lifestyle of consumers. Therefore, it could create ”win-win-win” situation among the consumers, power company and the whole society. |
