近年來，隨著再生能源與儲能系統廣泛推廣與佈署，分散式能源在現今電力系統中受到越來越多的關注。在許多研究中，微電網被視為聚合所有分散式能源且提供消費者能源服務最有效的方式之一。為了鼓勵微電網營運商投資分散式能源，本文提出基於共享經濟想法的容量共享機制。將微電網營運商所擁有的分散式能源中，把閒置的能源或是容量透過共享經濟的營運方式提供給需求者。透過分散式能源容量共享的想法，微電網營運商可增加利潤。此外，用戶可透過租賃閒置的分散式能源並相對應地調度能源需求使能源成本的支出最小化。
為驗證所提出的共享模型之有效性，本文採用市場供需平衡模擬微電網營運商與用戶之間的競價關係，並採用一年的太陽能與用戶負載實際數據做為驗證。此外，為顯示該模型的經濟效益，我們也對所提出的方法進行靈敏度分析。模擬結果顯示所提出之方法可有效提升電網營運商的利潤而用戶也可減少能源購買的成本。未來再生能源及電池投資成本降低，電網營運商能投資更多容量至微電網中增加獲益，而用戶也可以購買較多的太陽能與儲能系統服務以滿足需求。

Distributed energy resources are gaining more attention in recent years thanks to the high penetration of both renewable energy source and energy storage system embedded tightly in current power system. Microgrid, by integrating those Distributed energy resources to its network, could be a quick start to a promising business. A microgrid operator, the one in charge of the entire microgrid can apply the idea of sharing economy to provide energy to eventual consumers. Capacity is the sharing item in this business. The main target is minimizing consumers energy purchased cost while maximizing grid operator revenue.
To achieve those goals, a smart scheduling process is proposed once a finite number of customers are being engaged to this business by renting a certain amount of capacity. One-year real data have been used in the proposed method evaluation. A sensitivity analysis is done along with interpretations to show the effectiveness of our proposed method illustrating sharing economy benefits. The results show that the proposed method can increase operator’s profit while users reduce their energy cost. Furthermore, operator can invest more capacity of photovoltaic (PV) and energy storage system (ESS) to earn more profit due to the install cost declining in the future, and so users can purchase more service of PV and ESS to meet their energy demand.
