| Summary: | 碩士 === 國立臺灣海洋大學 === 輪機工程學系 === 105 === The rise of environmental protection and the progressive exhaustion of traditional fossil energy sources have increased the interests in integrating renewable energy sources and electric vehicles (EVs) into existing time-of-use (TOU) rate users. However, installation EVs and their charging/discharging systems are costly for a large scale TOU user. Therefore, development of more innovative and sophisticated energy management systems (EMS) to coordinate the EVs charging/discharging load and TOU user’s load, and increase the economic benefits of EVs may become a more important issue in assessing whether the TOU would agree to set up EVs and their charging/discharging systems. The goal in this dissertation is to develop the direct search method (DSM) to solve the operating schedule of a renewable energy based TOU rate industrial user with large EV penetrations and battery energy storage system (BESS). The developed DSM software is a useful tool to evaluate the effects of electric vehicle charging/discharging strategy, operation mode and penetration level on the operating schedule of a renewable energy based TOU rate user. The computer program developed in this research can also be a power tool for TOU rate industrial users to evaluate the economic benefits of EVs. The results may serve as a tool for Taiwan power company and TOU users to assess and set up EVs and may serve as a reference for domestic promotion of smart grid, thereby contributing positively to the promotion of smart grid and EV.
