Optimum Planning of Capacities of DER and Energy Storage Facilities in the Microgrid
摘要
摘要 對於地球溫室效應日益嚴重及能源短缺，世界各國開始重視利用再生能源以解決能源危機、石化燃料成本高漲及氣候變遷的問題。世界各國將再生能源納入微電網相關的研究與建置內，使微電網的技術呈現蓬勃發展的趨勢。 現今微電網主要是利用分散式電源加上儲能系統，搭配適合的控制及通訊技術，以供應微電網內負載之電力需求。具備增加再生能源發電滲透率、提高用戶供電可靠度及供電品質、減少輸電損失等特性。微電網可分為獨立運轉或市電併聯兩種供電模式。本研究是對於獨立運轉型微電網內分散式電源及儲能設備容量之規劃提出適當的方法。由於儲能設備在微電網建置成本中佔有一定的比例，因此，微電網儲能設備容量的規劃，是建置微電網的重要研究議題之一。 本研究參考核能研究所微電網的規模(負載及再生能源資料)，針對獨立運轉情況下微電網內分散式電源及儲能裝置容量進行最佳規劃。本研究對於分散式電源及儲能裝置的成本建立完整的數學模型，在考慮再生能源發電特性及滿足負載需求的條件下，利用整數規劃法求解分散式電源及儲能裝置的最佳容量。並進而探討在其他不同假設情境下的儲能設備容量規劃。研究成果對於降低微電網建置成本和未來微電網的發展有一定的貢獻。

Abstract For global warming and increasing shortage of energy, countries around the world began to pay attention to the use of renewable energy resources to solve the energy crisis, the soaring cost of fossil fuels and climate change issues. Countries around the world incorporate renewable energy into the microgrid related research and implementation, so that the trend of micro-grid technology is booming. Today, microgrid is consisted mainly of distributed generation and energy storage system with proper control and communication technology to supply electricity demand. Microgrid can increase the penetration of renewable energy generation, improve power supply reliability and quality and reduce transmission losses etc. Microgrid can operate under islanding or grid-connected mode. This study proposes a proper method to evaluate the planning of distributed generation and energy storage capacities inside microgrid under islanding operation mode. Due to energy storage system occupies a certain proportion of microgrid installation cost, therefore, the planning of the capacity of energy storage is one of the important research issues of microgrid implementation. In this study, the size of microgrid in Institute of Nuclear Energy Research (load and renewable energy resources data) is referred to proceed the optimum planning for the capacity of distributed generation and energy storage inside microgrid under islanding operation mode. A complete mathematical model of the cost of distributed generation and energy storage system is established in this study. Considering the characteristics of renewable energy generation and the demand of load, integer programming is used to solve the optimum capacity problem of distributed generation and energy storage. Other different assumptions are also investigated. The research results of this study give contribution for reducing implementation cost and promotion of micro-grid.
