Idc and energy storage

How much energy do IDCs use?

According to the United States Data Center Energy Usage Report (Ref. ), IDCs in the U.S. consumed an estimated 70 billion kWh in 2014, accounting for about 1.8% of total U.S. electricity consumption. Ref. shows that the energy demand from IDCs in 2019 was around 200 TWh, comprising around 1% of global electricity use.

Should power utilities invest their own IDCs?

With deep integration of cloud computing in industrial systems, there is an emerging trend that power utilities invest their own IDCs (i.e. private IDCs that only provide access to grid stakeholders and other authorized parties) to provide cyber infrastructure support for grid operation.

How do IDCs and grid energy resources relate to cyber-physical entities?

Compared to existing work, the proposed approach treats IDCs and grid energy resources (BESSs, renewable energy sources, etc.) as integrated cyber-physical entities and investigates their coupling impacts. The proposed framework also models and considers different kinds of computation requests and their operational constraints.

What is the computing capacity of an IDC?

The computing capacity of an IDC is defined as the maximum number of requests it can handle in one time slot. For an IDC with m server racks, its computing capacity is mμ. Meanwhile, the maximum number of requests it can buffer is mQ.

How can a networked internet data center improve quality of service?

The numerical case studies show that by properly utilizing the temporal-spatial load shifting flexibility of networked Internet data centers and coordinately planning the data centers’ and battery energy storage systems’ locations and sizes, the system’s quality-of-service, economics, and reliability can be significantly enhanced.

How do IDCs work?

In the framework, the IDC investor plans the location and capacity of IDCs and submits the IDC construction plan to the utility; the utility then checks the grid’s security under the suggested plan. Based on the feedback from the utility, the IDC investor revises the IDC plan until it satisfies the grid’s operation requirements.
