現今，溫室效應的日趨明顯、智慧電網技術的快速發展、再生能源發電占比的不斷提高，已使「低碳社會」、「非核家園」、「永續能源」等政策不再流於口號，而是可以實現的目標，必須努力踐行的政府永續發展政策宗旨。然而，由於風力發電系統與太陽光電發電系統等之發電受天候、時間、季節變化等的影響甚大，具相當之不確定性。再者，儲能系統將為未來電網多元能源發電系統整合與調度不可或缺的設備，電業若不及早投入電網級儲能系統的研發、裝設、控制、整合管理與協調調度，未來勢將無法供應乾淨、穩定、低價與可靠的電力，更難使電網中各種各類能源資源為平穩之協調與互運。因此，我國電網如何優化及相關法規體系如何規劃等之探討實為當務之急，方利因應我國未來電業自由化、智慧化、低碳化等之發展。本研究除蒐集國內外電網相關技術與法規資料、探討智慧電網技術之發展與趨勢、評估臺灣電網優化之方法與策略外，尚參考國外分散式再生能源系統併網運轉之調度與管理機制，俾博徵廣引，研提出我國妥適之電網優化策略及法規體系規劃建議。

Nowadays, with the obvious tendency of greenhouse effect, the rapid development of smart grids and the constantly growing proportion of renewable energy system, the policies of “Low-carbon Society”, “Nuclear-free Homeland” and “Sustainable Energy” are not merely slogans, but achievable goals and aims of governmental sustainable development policy that people must spare no efforts to accomplish. Due to the limits of weather, time and season changes for the wind power generation system and photovoltaic power generation system, both of them have the considerable uncertainty. Besides, the energy storage system will become the necessary components for the future grids with multiple energy generation system integration and distribution. If the power companies do not put their efforts of development, installation, control and integration management in the grid-scale energy storage system as soon as possible, they will not offer clean, stable, low-price and reliable electricity, which will make the energy resources of grids maintain the steady coordination and interoperability much harder. Therefore, it is the top priority to deal with how to optimize our grids, revise its related laws and design future plans in response to the development of our power industry deregulation, intelligence and low-carbonization. This study not only collects related information of technology and laws of grids internally and abroad, investigates the development and trends of smart grids techniques, evaluates the optimization methods and strategies of Taiwan grids, but also refers to the mechanism of distribution and management from foreign decentralized renewable energy system and grid operation to make this study much more informative and propose appropriate suggestions for our grid optimization strategies and laws.
