Energy infrastructures face significant challenges with increasing renewable energy adoption. Wind and solar power exhibit dynamic fluctuations spanning multiple timescales that require significant amount of flexibility. Various new technologies provide huge opportunities for shifting flexibility, such as energy storage and modular manufacturing systems. One exceptional source of flexibility arises from the computing infrastructures, where large-scale data centers can be orchestrated to modulate their power loads via computing task migration and scheduling. Despite huge economic incentives, lack of infrastructure coordination makes flexibility provision difficult.In this dissertation, we develop a novel energy market clearing framework that capture shifting flexibility from various resources in a unified manner. Our framework proposes the concept of virtual links to explicitly capture shifting flexibility, which treats shifting of energy loads as a service. Under our framework, such shifting services are remunerated via spatial and temporal price volatility, and in the meantime, capturing flexibility benefits the market by mitigating price volatility overall. Specifically, we show that virtual links can be applied to capture shifting flexibility from data centers and energy storage systems, among others. On the flexibility provision side, we also formulate a receding-horizon resource management model for data centers to study how much flexibility one data center can provide when given the right signal from the power grid/market. Finally, we propose a systematic approach to quantify the amount of flexibility provided in a market with virtual links based on the concept of flexibility index. This approach demonstrates that even adding a small amount of virtual links contributes to significant increases in the grid's ability to tolerate uncertainties posed by renewable generation.
