"環保意識的逐漸高漲與傳統石化能源的即將耗竭，促使電力系統有極高的興趣倂入風力能源與智慧電動車，然而當孤立電力系統併入大量的風力能源與電動車時，由於風力能源發電輸出的不確定性以及電動車充放電控制的隨意性，將增加系統操作者在電力調度上的負擔，其中一項相當重要且極具挑戰性的問題即是如何有效地管理風力能源輸出發電量的變動性，另一項重要議題則是如何評估大量電動車倂入電網對於發電端、輸電端及配電端所帶來的衝擊。本研究計畫之目的擬提出分層分區之能源管理系統架構，探討大規模電動車與電網雙向互動之多層多區的調度模式，期能一併解決各區域備轉容量分配、區域間壅塞管理、風力發電不確定性及電動車充電隨意性的問題，進而探討各區域電動車集總儲能系統與風火力發電系統之間的協調問題，以改善孤立電力系統運轉的效率與可靠。本研究計畫擬以三年時間探討大規模電動車與風力發電量併入電網之關鍵議題，分別從(1)底層調度：複合能源時間電價用戶因應設置電動車運輸系統之能源管理系統開發，(2)下層及中層調度：電動車代理商(電動車聚集體)與多個時間電價能源用戶雙向互動之調度模式，及(3)上層調度：臺電系統調度機構與北中南各區域電動車代理商雙向互動之調度模式三個角度，探討大規模電動車併入電網的可行性及效益，進而規劃各區域電動車代理商與能源用戶之最適充放電策略。研究結果可以作為電力公司及時間電價能源用戶設置電動車推動智慧電網的參考，對於臺灣推動智慧電網及電動車會有正面的助益。"
"The rise of environmental protection and the progressive exhaustion of traditional fossil energy sources have increased the interests in integrating wind energy sources and electric vehicles (EVs) into existing power systems. However, it is widely believed that large wind and EV penetrations would put an increased burden on system operations due to the uncertain nature of wind power and uncontrolled charging/discharging procedure of EVs. One of the most important future challenges seems to be the management of the integration of fluctuations in the electricity production from wind energy sources. Another important issue regarding the integration of EVs into an isolated system is to assess the impact on generation, transmission and distribution grid side. A new conceptual framework based on a three-level hierarchy for energy management system (EMS) is developed for achieving optimal utilization of wind energy sources and electric vehicles energy storage system. Several key issues of EV-wind-thermal coordination dispatch in a power system are also investigated and discussed in this research to ensure the security and reliability of the isolated system. This research proposes a three-year project to investigate the key issues of integrating wind energy sources and EVs into existing power systems. The research topics are as follows: (1) bottom level: development of energy management system in a hybrid energy source time-of-use (TOU) rate user with EVs, (2) middle level: development of EV charging strategies between aggregators and TOU rate users, and (3) top level: development of wind-EV dispatch model between aggregators and Taiwan control center. The computer program developed in this research can be a power tool for EV aggregators and TOU rate users to evaluate the charging/discharging systems design and 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."
